The operational and safety elements of cooling towers. This is the first of a two-part series. The operating and safety features of cooling towers will be describing here. The control and optimization of these variables will be discussing in the next column. The series will be split into mainly two parts. The functioning and safety of cooling towers are mentioning in this article. The control and optimization of these processes will be discussed in the next column. 

Cooling towers (CT) are water-to-air heat exchangers that we use to release waste heat from industrial processes into the atmosphere.

They range in size from small roof-top units to extremely huge hyperboloid structures. This can be as tall as 200 meters (660 feet) and 100 meters (330 feet) in diameter, or rectangular buildings that are more than 40 meters (130 feet) tall and 80 meters (260 feet) long. When they’re working properly, they keep the plants safe, but when they don’t, overheating can lead to terrible accidents. Their operational costs are the sum of water and air transportation expenses; thus, if these costs can be decrease (optimize), the plant’s running costs will be reducing significantly. 

Terminology and use of cooling towers

The chimney effect, which transports outside air through the tower, is used by all cooling towers. The difference in density between the incoming colder outside air at the bottom and the air inside, which is lighter because it is warmer and more humid, determines the air movement induced by the chimney effect. The humidity of the air rises in the column. This is because water continues to evaporate as long as its temperature is higher than the air’s wet-bulb temperature. This evaporation reduces the density of the inner air and produces some water loss, which necessitates makeup. The lower-density inner air rises as the heat of the water is transmitted to the air, drawing in the fresh air at the foot of the tower. 

Safety of the cooling system

As the number of components in a cooling system is reducing, its safety improves. The availability and good functioning of air and water conveyance equipment are require for the proper operation of traditional industrial cooling tower systems. The most essential element in terms of safety is the availability of the power supply to these components. Backup power supplies can increase safety, but as we’ve seen in countless accidents, backups can also fail. 

A cooling system’s safety decreases as the number of components increases. Cooling systems that use cold water are the least safe in this regard. The process heat is transmitting to chill water first, then to cooling tower water, and eventually to the air. It is the least secure because it is mainly of four components, each of which could fail or lose power.

As a result, the plant’s safety will be enhancing if the process can be modify to function directly with CT water, eliminating the chiller. If the tower’s cold water isn’t cold enough, it must be transferring to a chiller for extra chilling before using it to cool the process. “Optimization of cooling systems” went over the safety and optimization controls of chilled cooling systems in great depth. A cooling system’s reliability can be improved even more by limiting the number of functioning components to just one. This is the situation with no-fan natural-draft cooling towers. 

Bottom Line 

As it is self-actuated and uses the always available natural energy sources of gravity and thermal expansion, the safest and most reliable cooling system is one that does not require any man-made electricity. Such a cooling system is simply a notion (it does not exist), and I detailed it in my article on nuclear safety.

In general, we construct wastewater treatment plants to prevent various types of pollutants from polluting the water environment. As a result, they must meet the required effluent standards. However, in practice, the results are frequently inconsistent with the design parameters expected from the project.

We can take several examples to demonstrate some common causes of malfunction. There may be issues with the sewage system, plant design, technical equipment, hydraulics, and, of course, maintenance due to the under training of personnel. Simple advancements in sewage and plant system technology, as well as adequate personal training, can frequently be used to solve wastewater treatment problems instead of costly reconstruction.

Moreover, water pollution is becoming a serious impediment to any society’s long-term development.

Water quality management is one of the most significant burdens on the weak economies of many transitions or developing countries. 

Stormwater drainage, sewer reconstruction, sludge disposal, and also recipient section regulation are frequently much more complicated and costly too. 

Problems: 

The first issue is that Floc is too small:  

Solutions 

• We can also do jar testing to ensure proper chemical dosage.
• Examine your drawdown and metering for low chemical metering.
• Your chemical feed pump may be set too low. If necessary, increase the feed pump or drawdown rate.
• Examine your pH and control calibration, and make any necessary adjustments. 
• In the flocculators, check the paddle speed. The speed could be too high, resulting in floc shear.
• Make sure you have a good injection point and adjust it if necessary.

The second issue is that Floc is too big:

Solution

• This problem is usually caused by incorrect chemical dosage. Moreover, Jar testing is an excellent way to double-check your dosage.

The third issue is that wastewater settles too quickly:

Solutions

• Examine your drawdown and metering for low chemical metering.
• Make sure you have enough dilution water.
• Inspect the injection points for polymer or coag. We should optimize them to maximize solid’s contact and reaction time.

Floating sludge is the fourth issue:

Solutions

• Your sludge collectors must be operational at all times. Examine the motors, chains, drive belts, and other components.
• Check the operation of your sludge pump. Do the pumps and pipes have debris in them? If necessary, use the standby pump.
• By conducting jar testing, you can look for changes in influent flow, pH, or chemistry.
• Are the polymer and coagulant concentrations correct? To test, run jar testing.

Solids loss over the effluent weir is problem number five:

Solutions

• We can also do jar testing to ensure proper chemical dosage.
• Examine your drawdown and metering for low chemical metering.
• Your chemical feed pump may also be set too low. If necessary, increase the feed pump or drawdown rate.
• Examine your pH and control calibration, and make any necessary adjustments. 
• In the flocculators, check the paddle speed. The speed could be too high, resulting in floc shear.
• Check the alignment of your baffling inlet and outlet and also make any necessary adjustments.

The next problem is thin sludge or a thick sludge blanket:

Solutions

• Check that your cross-collectors are operational. Examine the motors, drives, and also the belts.

The sludge collector is jerky or does not function is number seven:

Solutions

• Examine the sprocket, chain link, flight, and also shear pin on the collector. These components should be repaired if they are damaged.
• If the sludge blanket is too thick, it may be necessary to pump it out. If necessary, we can do this by hand also.

Solids carryover with effluent is problem number eight, but a good sludge blanket can help.

Solution

• Your sludge blanket is probably too thick. Increase your flight speed or low flow rate to counteract this.

Problem nine is that the float is too thin, but the effluent is satisfactory:

Solution

• Reduce the flight speed or increase the flow rate.

Poor effluent quality and thin sludge are problems number ten.

Solutions

• The air/solids ratio could be too low. Increase the amount of air coming in.
• It is possible that the pressure is too high or too low. Recycle the valve by opening or closing it.
• Is the recycle pump turned on and operating correctly? Examine it for damage and functionality.
• The chemical addition may be insufficient. Chemical dosages can also be checked using jar testing.
• It is possible that the loading is excessive. If this is the case, reduce the flow rate.

Bottom Line

As you can see, it takes a significant amount of time to run a wastewater treatment plant efficiently and also in accordance with local discharge regulations. The problems and potential solutions identified above should give you a better understanding of how to correct them. But ultimately, choosing the right STP at the start of the process goes a long way toward ensuring the plant is easy to maintain and fit for purpose. 

However, selecting the right wastewater treatment plant at the outset of the process goes a long way toward ensuring that the plant is simple to maintain and fit for its purpose. Please contact us now for more information on how to choose the best technology!

The velocity and temperature of the water returning from the process determine the load on a cooling tower. The temperature of the cooling water that is returning to the process is the controllable variable. We then regulate the airflow through the tower, and which can then modify either by modifying the speed of variable-speed fans. We can also alter them by turning on and off a number of variable-speed fans. 

A cooling tower’s work in a power plant is to remove the heat absorbed in the circulating water systems evaporatively. 

The airflow entering the tower’s entrance determines its efficiency to a great extent. The performance of the cooling tower is harmed by turbulent airflow at the air intake. This limits power output, especially during hot summer months. 

The preparation of food and beverages necessitates a wide temperature range. This requires the installation of efficient cooling systems to deal with the extra heat. A cooling tower is necessary to remove surplus heat from the system, but traditional designs require constant maintenance. This article shows how to make cooling towers more efficient. 

How to Optimize Cooling Tower

Traditional fans use induction motors that spin at 1500 rpm and are coupled to a driveshaft, which is connected to a gearbox, which is then connected to the fan. Because there are so many moving parts, the system is prone to malfunctions. Additionally, gearbox maintenance is time demanding, and oil leaks are prevalent owing to the environment. Modern cooling fans require motors that we need to install directly on the fan and can withstand the conditions inside the cooling tower to combat this. We can replace many of these older motors with more energy-efficient permanent magnetic motors. This can be mounting directly on the fan. As a result, the number of parts in the system will be reducing, lowering the risk of failure. They’re also smaller than standard cooling tower motors, which means the system takes up less room.

Furthermore, we may use the fans to prevent freezing during the colder months of the year because the motors are reversible. This helps to enhance cooling towers by minimizing noise pollution. The improved efficiency of permanent magnetic motors, especially at partial loads, together with the drive’s variable speed control, assure quick operation of the fans at the needed speed, saving energy, decreasing CO2 footprint, and minimizing running costs. 

More methods to optimize Cooling Tower

We can use the drives, such as ABB’s ACS880-01 industrial drives with permanent magnetic motors. We can use cooling tower application control programs to make this happen. This enables the industry to match the motor speed to the demand of the process. As a result, cooling towers will be able to operate for extended periods of time while requiring less maintenance. Overall, updating cooling tower systems can save a lot of money and provide a stable production platform that can help your company develop. Traditional cooling technologies, particularly cooling fan motors, are no longer sufficient to meet the system’s demands. The only way to boost output is to optimize processes by implementing new technologies.

Optimized controls

The cooling water temperature (Tctws) rises as the approach increases, as seen in Figure. The temperature differential between the process cooler and the process cooler (Tp – Tctws) is also minimized. The approach controller TDIC-1 throttles the air fan speed to keep the setpoint (SP-1) constant. A valve position controller calculates the optimal pump speed (VPC-4). This serves to minimize the need to add and remove the needed amount of water that is getting cooled inside the water area. This helps to reduce pressure drops at all of the plant’s cooling water valves. We then observe and update the data for the cost curves on a regular basis based on actual fan and pump running costs.

Temperatures of supply and return water that are optimal

The approach controller optimizes the temperature of the supply. When the water is at the most cost-effective temperature, it will be optimum. TDIC-1 regulates the cooling tower’s cooling water supply temperature. TDIC-2 is the range controller, and the optimum setpoint of SP-2 is used to set it. PDIC-3 detects the load and increases the pump speed if its output exceeds that of the range controllers. We require the external reset feedback on all TDIC-2, PDIC-3, and VPC-4 controllers. This guarantees that all users benefit from increased cooling while the system’s pressure loss is kept to a minimum. Increasing the setpoint reduces the safety margin while increasing energy conservation.

The optimization of cooling towers is typically only a small portion of the overall cooling system optimization in most industrial operations. The reason for this is because the cooling tower water temperature is too high. We use chillers in these situations to further lower the water temperature. Furthermore, optimizing the resulting chiller-tower combinations becomes both more difficult and profitable. 

Bottom Line 

A cooling tower system is one of the most energy-intensive systems. As a result, many industrial companies seek to make their cooling towers chill as much water as possible through evaporative processes while using as little electricity as possible. 

Assess the cooling tower’s energy consumption, which mainly consists of fan and pump horsepower (HP). At the very least, ensure that the cooling tower fulfills ASHRAE 90.1 criteria in terms of HP per cooling tonne. Cooling towers only use a fraction of the horsepower available most of the time since they are mainly design to meet cold water requirements on the hottest, most humid days.

Cooling towers release heat from recirculating water used to cool chillers, air conditioners, and other process equipment into the atmosphere. Evaporation removes heat from cooling towers and discharges it into the environment. As a result, cooling towers consume a substantial amount of water by design. 

Environmental restrictions and pollution prevention are the goals of best management practices of a Cooling Tower. This best management practice includes a set of propound operating procedures and instructions.This aids in the reduction of pollutants released into the JEA Publicly Owned Treatment Works. The goal of developing this BMP is to safeguard the POTW and the environment while not unreasonably burdening cooling tower-using establishments. We use a cooling tower mainly in a variety of businesses, hospitals, institutions, and office buildings. We also use them in open recirculating cooling water systems to reject heat through evaporation. Evaporation from cooling towers dissipates heat from HVAC systems and other operations into the atmosphere. 

The goal is to discover how a cooling tower consumes water and also to develop a set of best practice suggestions to help the tower operator or water treatment service provider reduce total tower water consumption. 

Practices

In open recirculating cooling water systems, mineral salt concentrations rise as evaporation occurs. Fouling and scale formation on heat exchange surfaces can happen when the concentration of mineral salts exceeds their solubility. Cooling systems regulate the amount of dissolved solids in the system by removing a portion of the recirculating water and replacing it with new makeup water. Water in cooling towers can be cycled several times before becoming saturated and needing to be discharged. Blowdown refers to the removal of water from recirculated cooling water in order to reduce pollutant buildup in the tower water. To avoid fouling and make optimal use of the makeup water supply, we need to maintain cooling tower blowdown. We frequently use the sanitary sewage system to dump this water. 

Most recirculating cooling water system maintenance programs also include controlled applications of conditioning chemicals, in addition to blow down. Microbiological control, corrosion prevention, and increasing the solubility of mineral salts are all reasons for chemical additives. However, the scale and bacterial development can reduce the efficiency of heat exchange systems such as cooling towers, condensers, and heat exchangers. Molybdenum is a common ingredient in cooling tower chemicals. We mainly utilize them in cooling tower treatment chemicals as a corrosion inhibitor or as a tracer to determine the treatment chemical concentration. Because of its propensity to passivate cathodic surfaces, molybdenum has been utilized to prevent corrosion in cooling water systems for a long time. 

Required Maintenance Practices

• By automating blowdown and repairing leaks, you can control the concentration of dissolved minerals and compounds in the cooling water. Leaks in the recirculating cooling water pipe and basin should be kept to a minimum. Leaks wastewater and chemicals, reducing the number of possible cycles. Maintaining the proper chemical composition is critical for two reasons: equipment protection and system efficiency. 
• Allow a cooling water treatment firm to examine the makeup water’s chemical composition and suggest a particular water treatment program for your makeup water and usage. Routine analysis of the recirculating cooling water should be part of the procedure, with blowdown and chemical addition rates adjusted accordingly. 
• Schedule and proper routine monitoring and maintenance activities to ensure that cooling water meets the client’s specifications.
• Include specific guidelines in any service contracts or agreements that address chemical substitution options. 
• To keep concentration cycles under control, test cooling tower water on a daily basis. 
• Install totalizing flow meters for the influent and effluent to monitor the cooling tower’s operation.
• Keep tower decks clean to avoid water loss due to overflow.
• To maximize the evaporation rate, keep the tower fan in good working order.
• Clean the sensor on a regular basis with procedures that use automatic bleed equipment.
• Check the meter’s calibration with a probe.
• In compliance with applicable rules, check the discharge water quality on a regular basis.
• Maintain the fill level of the cooling tower to prevent water from dripping or splashing out onto the ground. The basin should collect all of the water that passes through the fill.

Guidance

• We must reduce the blowdown by working closely with your water treatment vendor or contracted service provider. Consider performance-based contracts because decreasing blow down minimizes the amount of chemicals needed.
• Vendors should be required to meet a minimal water efficiency standard.
• Make it clear to your vendor that water conservation is a top issue, and inquire about alternative solutions for reducing blowdown.
• Request that your provider gives a written report for each service call, as well as an explanation of the test results. 

Wrap up

Many air-conditioning and refrigeration systems include cooling towers, which work by evaporating water to remove heat. Wet/evaporative cooling towers are commonly used to offer thermal comfort for significant commercial buildings as well as process cooling for businesses like oil refining, chemical processing, power plants, and a variety of manufacturing processes. However, the quality of the cooling tower’s recirculating water has a direct impact on the cooling tower’s thermal efficiency, good functioning, and lifespan. Therefore, maintaining water balance, maximizing concentration cycles, and optimizing blow down offers the best chance for water efficiency. Moreover, they offer the least amount of environmental effect.

The post Best Practice and Guidance for Cooling Towers appeared first on Blog | Jateentrading Co..

If you’re in charge of a cooling tower, choosing which water treatment procedures are the most effective can be difficult. You have a few options if you’re aware that your water requires chemicals to help your cooling towers perform at their best. A specialist in water treatment can assess your specific water situation. They can moreover advise you on the chemicals that are most necessary.

However, going into the conversation with a basic understanding of your options will make the process go more smoothly. We use heat exchange to power cooling towers. Water circulates continuously throughout the system, and when it reaches the cooling tower, which will be heating up by industrial activities. Finally, this will be exposing to the air, results in evaporation. The temperature of the water is then lowered to the point where it can be recirculated. This is done so that we can use them for cooling. This evaporation cycle necessitates the ongoing replenishment of water supplies. The water that we feed into the cooling system, on the other hand, is often contaminated. This can lead to scale and corrosion. These concerns are addressed and prevented by the chemicals used by water treatment firms.

What chemicals we use to Clean Cooling Towers?

Chemicals in the water are beneficial to almost all cooling towers and HVAC systems. We use these compounds, which differ in function and type for a variety of applications.

We use chemicals primarily to extend the life of the cooling tower and prevent concerns such as fouling, corrosion, etc.

Corrosion Inhibitors:

Corrosion and degradation of metal parts in cooling towers are common problems owing to natural breakdown. This can produce rust and other compounds that break down metal. This corrosion weakens the mechanical sections of a water tower over time, causing malfunctions and water contamination. Bicarbonates are the most widely using corrosion inhibitors. By neutralizing the acidity in the water, these compounds protect metal components. Bicarbonates attack corrosive substances like chlorides and sulphates directly, which chip away at the structure and components of a cooling tower over time. 

Algaecides & Biocides:

Another major problem with cooling towers is the accumulation of organic waste. This can range from algae and biofilms to organic impurities introduced into the water as a result of leakage. Because these materials are alive, they can spread quickly and overwhelm a cooling tower. As a result, we treat most cooling towers with a biocide (anti-biotic) to prevent a rapid bloom or burst of biological life that fouls system components and poses health risks. Algaecides are mainly to kill algae and other plant-like organisms in water, as their name suggests. Biocides can help remove any remaining living matter in a cooling tower. They can also enhance the system, and ensure clean and adequate water utilization. When it comes to biocides for your water, bromine is one of the most prevalent solutions.

Scale Inhibitors:

Scaling is one of the concerns that cause the most damage and strain to a water tower’s systems. When an undesired item or contaminant in the water accumulates in a specific region, deposits can form that increase over time. This can result in a variety of problems, including pipe narrowing, total obstructions, and equipment failure. The presence of minerals in the water usually causes scaling, and the alkalinity of the water will influence how much calcium carbonate scale you’ll get. Silica is also renowned for forming massive deposits, which might degrade your system’s performance. You might be able to use phosphoric acid to combat scaling in your cooling tower.

Importance Of Cooling Tower Water Cleaning

You may believe that cooling tower water treatment is unnecessary if your cooling tower is currently performing well. Common problems like corrosion, pollution, and scaling, on the other hand, can cause serious complications, and it’s impossible to predict when or where they’ll happen. Fouling in a cooling tower can result in a complete loss of output, long downtime, and a lot of trouble and money in the form of repairs. This is why working with a qualified water treatment professional who can assess your specific cooling tower water treatment system is vital. They also give you advice on the following actions to take, such as changing your approach or incorporating a water treatment system for the first time. Because of the enhanced longevity, efficiency, and effectiveness in your cooling tower, the initial investment of time and money will more than pay off many times over in the long run.

The post CHEMICALS USED IN COOLING TOWER appeared first on Blog | Jateentrading Co..

Usually, we remove heat from the building via cooling tower. We can accomplish this by using evaporation to cool a stream of water to a lower temperature. We use commonly large cooling towers in sectors such as power plants, oil refineries, and various manufacturing facilities.

Since industrial processes and machines produce too much heat, we need to do continuous dissipation for efficient operation. The heat must be directed at the setting. We can accomplish this by a heat exchange mechanism. That is the fundamental principle behind cooling tower technology.

Categorization of Cooling Towers

After several years of research and development, cooling towers are now available in various shapes and sizes. Each of these applies to a specific load configuration, so it is necessary to detail the options available. Here are some categorizations.

1. Mechanical draft cooling tower
2. Atmospheric cooling tower
3. Hybrid draft cooling tower
4. Air flow-characterized cooling tower
5. Construction-characterized cooling tower
6. Shape characterized cooling tower
7. Cooling tower based on the method of heat transfer

What are the types of cooling towers by build, heat transfer methods, and airflow generation methods?

We categorize the cooling towers commonly according to their build, heat transfer methods, and airflow generation methods. We will look at each kind of cooling tower:

Cooling towers by build:

• Packaged cooling towers: Packaged cooling towers are pre-fabricated. The shell is usually constructed of a corrosion-free, heat-resistant, and long-lasting material such as fiberglass-reinforced polyester. They are readily transportable to a facility of choice since they are pre-assembled. Since they are lightweight, they also favour in facilities with low heat rejection criteria.
• Field erection: We often find these massive units in power plants and extensive industrial facilities. When comparing to package type, these are large structures. We can manufacture or build them according to custom specifications.

Heart transfer methods: 

• Dry cooling towers work by transmitting heat across a surface that separates the working fluid from the surrounding air. This works on the theory of heat transfer through a heat exchanger with extended fins. The fan is driven by an electric motor. As a result, dry cooling towers use no water. 
• Wet cooling towers or open-circuit cooling towers: These are the most common cooling towers due to their low cost and sustainable nature. They use water to cool the plant, and we can determine heat transfer by a decrease in process temperature and a rise in the moisture content and wet bulb temperature of the air flowing through the cooling tower.    
• Drift pollutants are common in wet cooling towers: We use multiple drift eliminators to mitigate cooling tower drift, even though they are not environmentally harmful. As compared to other forms of cooling towers such as dry or fluid, the evaporation of water in a wet-mechanical draft is inherently more energy efficient.
• Closed-circuit cooling towers or fluid cooling towers: In closed circuit cooling towers, we often combine water with glycol to create a fluid. This fluid circulates in the tower in a coil that is not in direct contact with the air. We usually use them where the soil must be sterile and free of pollutants. The benefit is that there is no scale formation, resulting in higher efficiency and reduced downtime.

Airflow generation methods: 

• Natural draft cooling towers use the tower’s form and shape to transfer air up the tower using fans naturally. They employ the rule of varying densities between the ambient air and the warm air in the tower. As a result, these towers are tall in order to induce airflow, and it looks as a hyperbole.
• Mechanical Draft towers usually use a fan to move air into the structure. We pump the air inside the tank using a propeller or centrifugal fans. Regular draft towers have a much narrower design. Since the fan speed can be controlled, capacity management is simple in these towers.
• We design Cross Flow cooling towers, so that air flows horizontally and water flows vertically. We can accomplish this using open trough systems equipped with nozzles in the fan deck. Since the airflow contact time is shorter, more air is available for heat transfer. This cooling tower style has many drawbacks, including higher power consumption due to the requisite airflow.
• Counterflow employs hot water that arrives at the top and leaves at the bottom, while air is added at the bottom and exits at the top. They use both forced and induced draft fans. The water distributes through a channel of lateral pipes outfitted with splash spray nozzles. Their power demand is smaller than that of cross-flow units, and they are easier to maintain.

Maintenance of cooling towers

It is essential to perform routine structural maintenance on your cooling towers in order to ensure reliable throughput. We at Jateen Trading Co. provide both good repair manuals and maintenance plans that will help you save both time and money on your operating expenses. Our procedures and high-quality products can avoid heat transfer segment quality loss by ensuring sufficient water flow and airflow and preventing cooling tower corrosion. Check out our website to know more about our services and products. You can contact us if you have any questions regarding your cooling towers and our service.

We can determine the level of maintenance by the form of the tower, its height, and external factors such as your building’s geographical position. 

The following are some of the activities that you can do:

1. Using strainer devices as filters to collect waste and eliminate interaction between airborne and waterborne pollutants.
2. Wash the nozzles daily to avoid clogging. Since nozzles increase even water delivery, they should be mounted in places where they can be quickly viewed, tested, washed, or removed.
3. Water treatment options such as water simulation, green chemical use, filtration, and softening ensure that the cooling tower system works optimally and satisfies the necessary cooling specifications. This is recommended to do monthly for increasing your cooling towers life span.
4. Deep cleaning of cooling towers entails using a cleaning chemical that circulates and flushes through the structure. We use both both pressure washing and vacuuming in the deep cleaning process.
5. Mechanical components such as fans, engines, and belts must be tested, washed, and modified appropriately.
6. Electrical devices such as capacitors and wiring should be tested and, if possible, removed.

Bottom Line 

Finally, cooling towers are a critical part of any type of industry. It varies in scale, form, and style based on the needs of the building. The routine or regular servicing of cooling towers is crucial in order to increase their utilization. If you find this blog helpful, then please do check our rest blogs too.

The post cooling Tower: Types and its maintenance appeared first on Blog | Jateentrading Co..

Cooling towers are potent heat exchangers for a range of industrial processes which regulate temperature. If you find some issue with your cooling tower system, then you have to visit a company that provides good and quality cooling tower service for your system. If installation quality is supreme, then you will not experience such a maintenance problem. The cooling tower’s consistency affects operating performance, operating costs, equipment expense, and the reliability of the cooling system. Longevity depends upon maintenance even when quality machinery and equipment are built. You have to take care of the cooling tower from an experienced company even though you have it built. We at Jateen Trading Co. offer the best and top-notch services for our customer’s cooling tower system. 

Here, we need to consider a few factors in order to keep your cooling system efficient. We need to do periodical inspection or routine check. The experts must carry out the repair and maintenance. This would not only boost the life of the system but also minimize costs and avoid significant problems in the system. This is the only way to reduce considerable maintenance costs.

What are the cooling tower treatment problems, and how to solve them?

High amount of blowdown: 

Since cooling towers extract heat by the evaporation process, it is no wonder that they can, in turn, make the difference using a lot of water. Large quantities of solids will remain after evaporation, depending on the quality of makeup water added to the cooling tower and the device’s operating efficiency. This can contribute to an increased in need to “blow down” or remove solid waste and dissolved material from the flowing water before equipment can be scale or corrode.

Blowdown also contributes to water movement and chemicals and solid wastes, so it’s essential to keep a close eye on it. If you want too much blowdown in your cooling tower, the water treatment system can not operate as effectively as it should. An efficient water treatment system for the cooling tower would maintain a controllable blowdown. In turn, this helps to retain the quantity of any water or chemical composite material required and resulting in greater solid waste.

How to solve this issue:

Consult a cooling tower water management specialist if you need higher than usual blowdowns. Depending on the causes of the problem, some solutions to reduce cold tower blowdown can include:

• Enhanced water filtration feed.
• Filtration with high-quality side stream.
• An increased cycle of concentration.
• You need to maintain improved makeup water chemistry by eliminating impurities causing the formation and corrosion of the scale.
• Change or control the feed chemistry program for the cooling tower closely.

A low cycle of concentration:

In cooling towers, the cycle of concentration is a ratio of condensed solids to measuring the conductivity in blower water in the cooling tower process water. A facility should have a concentration interval of at least three to six cycles of concentration. The higher your concentration cycle, the less water and blowdown you need to make up and save water, toxic substances, and costs. Water consumption and chemical consumption can be substantially high for systems operating at low concentration cycles, contributing to over cost.

How can you solve them? 

The best solution is to visit the best cooling tower service, expert. However, several ways to improve your focus cycles will usually include:

• Better tower management by minimizing the conductivity of blowdown monitoring.
• Regulation of pH/alkalinity to reduce the formation size.
• Reduce the hardness of feed, iron, and silica.
• Microbial growth control.

Not accounting for secondary waste treatment:

Any discharge produced by your device must fulfill all local regulatory requirements. Feedwater contaminants affect secondary waste volume and processing requirements. We also need to process and discharge these secondary waste.

How to solve them?

You can get a copy of the permit specifications, study them carefully and plan your secondary treatment and downtime procedures. This will therefore fulfill the effluent release. This ensures that the plant meets or discharges the effluent targets.

Water scarcity/ supply:

These water scarcity facilities are already being faced, and hence, local restrictions on how much water you can collect and release will become tighter. You may have higher sewage link fees if your facility draws your water from or drains into a municipal source. If a cooling tower works ineffectively, there may be a surplus of makeup water and an unnecessary blowdown. Also, if your waste is returned to the area, the disposal of your cooling tower bleed would comply with the local municipal discharge law. So, in order to avoid being fined, it’s necessary to fix these problems directly.

How can you solve this?

Few more problems of cooling tower:

There are various problems that can occur during the cooling tower treatment process for companies that use cooling towers to eliminate heating from a manufacturing process or cool large buildings.

Since these problems always arise, it is useful to know what you should look for to save your time and money. Besides the problems mentioned above, the following can also cause:

• Corrosion: In cooling systems, corrosion is very common. Many industries, particularly in old cooling towers, accept corrosion as an unavoidable process. We keep cooling towers in open place, and thus, causing environmental effects by corrosion in the cooling tower. This problem becomes worse as the water’s pH levels become more unstable. 
• Scaling: Calcium phosphate, calcium carbonate, magnesium silicate, and silica in the water are insoluble in heated water. The insoluble compounds cause hard deposits to form on the heat exchange surface of the system. These developments are scaling. They damage the piping and inner cooling system surface.
• Fouling: If unnecessary materials are present in the cooling towers, then it is fouling. Fouling of the cooling systems is not only the result of the formation of dust, dirt, and derbies, but it also includes other materials such as slitting, microbiological growth, migratory corrosion products, sand, etc.
• Foaming: While not as frequent as the other principal causes of problems in cooling towers, the cascade of water in the tower can produce foaming. The cooling tower will either overflow, or the fans can blast moisture from the top of the tower.

You may not think much about the smaller and medium-sized industrial cooling towers that allow your plant to work. But that doesn’t mean you can neglect them. These towers are as important as any piece of equipment on your property that you have. In your water cooling towers, you can increase water quality and then maintain energy and save your money. The efficiency of cooling towers plays a vital role in maximizing commercial and industrial cooling systems’ overall efficiency. The industrial cooling tower, intended for an industrial one, is an integral element of the system. It would therefore be very beneficial and further necessary to sustain and moreover to increase its performance.

But how do you ensure that your cooling tower is in the most effective way possible?

Cooling towers consist of multiple components with different functions. The excellent performance correlates to the overall cooling process performance. In addition to tower component conditions, the cooling tower’s performance will depend on climatic conditions. Some considerations are considered when a cooling tower is built. These considerations include the temperature of the wet bulb, the cooling range, the approach to the temperature of the wet bulb, the rate of water circulation, the air velocity through the air passageway of the tower, and, of course, the height of the tower. These design parameters play a significant role in the cooling tower’s efficiency. 

industrial Cooling Tower

Cooling towers are typically some of the most cost-effective cooling mechanisms relative to other cooling technologies. It is still necessary to monitor your industrial cooling tower’s efficiency and operate it as smoothly as possible. This will guarantee that this facility can:

• Save energy.
• Decrease the volume of water consumed.
• Decrease the number of chemicals needed to treat water.
• Extend the service life of the equipment
• Reduce net operating expenditures.

Understanding the type of industrial cooling tower system:

Knowing the type of industrial cooling tower you have and how it operates is the first step in ensuring that your cooling tower runs efficiently. Different types of cooling towers are exposed to various pollutants, and specific types of treatment are needed for them.

Some of the common types are mentioned below:

Once through cooling tower system: To absorb heat from steam condenser draw water from a source and circulate the water through pipes. It then discharges the warmed water into the atmosphere. Generally, these systems are the simplest and most cost-effective choice for setting up and using cooling towers. Some facilities opt for other cooling solutions. For two purposes, one of which is local regulations, and the second, finding a facility in a region with enough water to draw from can be challenging.

Open recirculating cooling tower system: If your facility uses an open recirculating industrial cooling system, the same water is used and recirculated continuously during the process, eliminating heat by evaporation. Water reuse helps decrease the amount of water needed to operate the tower. However, this increases the risk of corrosion and deposition as the solids become more concentrated after evaporation occurs in the system. The heat can also promote bacterial growth in combination with open-air conditions and extract pollutants from the air.

Closed recirculating cooling tower: They work similarly to open recirculating systems, except the transfer of released heat to a heat exchanger without open-air exposure to any part of the process. When proper water chemistry is reached, this prevents pollution. Moreover, if there is a leak, the only time there has to be added make-up water to the device.

Understand the quality of source water needed to run the system:

Your precise water treatment specifications can differ, depending on the type of industrial cooling tower you run and how it works.

Feedwater to the cooling tower: You may or may not need treatment here, depending on the cooling water feed tower’s efficiency. In this cooling tower water process, if a water treatment system is essential, then the technology removes hardness and silica adjusts the pH.

Circulatory water in the tower: Usually, in the second phase, the cooling tower would require for the tower’s flowing water. This helps keep particles free from your cooling tower to build up and foul the cooling tower. A cooling tower’s chemical treatment will usually occur inside the tower at this phase. Proper chemical treatment minimizes the formation of scales, critical equipment corrosion. It also helps to disperse suspended solids so that settling in low-flow areas can be reduced.

Cooling tower bleed to drain: Blowdown or bleeding from the tower is the last part of the treatment for the cooling of tower water. This makes it possible to concentrate and remove liquid and solid waste, while processed water can be quickly returned and reused to the tower.

How to improve the performance of industrial cooling towers?

Piping change:

You can better manage your energy consumption with easy repairs, such as modifying the water piping. Changing one pipe to discharge blowdown water to return hot water will increase the cooling system’s total energy efficiency by up to 2%. However, it’s necessary to manage the equipment carefully. Consult with experts who knows about cooling towers or the replacement of pipes.

Focus on recycling:

Ensure the cooling tower is working and recycled correctly. It is essential for the management of water, preservation of energy, and saving money. Cooling towers of high quality are manufactured and engineered to recover at least 98 percent of all wastewater in the system. Recycling a large volume of water will contribute to substantial energy and water reductions. This will save money for your company and also boost the water quality.

Periodically inspect all equipment:

Inspections are an essential part of ensuring that cooling systems are functioning correctly. You will end up wasting even more energy and resources if you neglect them. In order to run and maintain an industry, it is essential to conduct daily maintenance and repair checks on your cooling system. You have to check for heat transfer areas, corrosion, biological growth, and any deposits of particle contamination. These damages and issues will reduce energy efficiency by at least 5% and maybe even more for the entire cooling system.

Increase cooling cycles:

It is also essential to know the number of processes your cooling tower uses. We can reduce make-up water up to 20% by rising water-cooling cycles. This can also reduce the blowdown of the cooling tower by up to half. Most individuals do not rely on cooling towers because they do not have the equipment high on their priority list. In order to conserve energy, save money, and run a smooth plant, it is necessary to improve water efficiency in all your cooling towers. 

Bottom Line 

For the effectiveness and reliability of your system’s operation, it is essential to be aware of possible cooling tower water treatment problems and know how to solve them. Consulting a water treatment expert is extremely necessary for determining the correct solutions for your cooling tower water treatment. The proper management of your system would be based on the individual needs of your plant. We also assist with adequate pretreatment of the cooling tower make-up water.

Industrial water treatment is a method used to manage different water purification and separation requirements, which is used for various applications. Since industry use water in production processes, impurities may directly impact the quality of the product. If we use unclean water in the production process, the undesirable contaminants can have a detrimental effect on the product’s quality. Industrial water treatment is, therefore, necessary. Industrial wastewater treatment uses the methods and processes to treat water that has been contaminated in some way. These processes treat the contaminated water and allow to reuse it. 

The primary purpose of industrial water treatment is to prevent scaling, biological pollution, and corrosion. They also ensure that all the standards are met for water disposal. Industrial process equipment such as boiler feeds, piping, and cooling towers must be secured. We must also protect that equipment from hazardous mineral salts, which can lead to system failure.

An industrial water treatment system will include different methods for various industries to achieve specific water quality. Other techniques commonly used in the industrial water treatment industry include the following:

• Ion Exchange 
• Media Filtration
• Degasification
• Ozonation 
• A chemical feeding system, and many more.

Advantages of Industrial Water Treatment?

Water plays a significant and important role in the lives of all. For processing and other processes, industries and factories use tons of water every day. Industry use water treatment to treat water, rendering it reusable for consumption, processing, or disposal. The main advantages of industrial water treatment are:

• Treating corrosion, scaling, and fouling: If the water used in a system is not adequately treated, then unnecessary corrosion, scaling, and fouling occurs, causing an adverse effect to the water system, plant, and equipment.
• Provides Clean and Reusable water: Using an industrial water treatment for treating wastewater will give clean water for reuse. If required, it can further be purified for human consumption. 
• Protect Environment: Many waste products, including chemical components, are present in the wastewater. It contains a toxic chemical that is discharge from the manufacturing industry, which is released to nature. The treatment of industrial water would eliminate harmful additives and chemical elements from the water. This helps you reuse the water and can also minimize environmental pollution.
• Keep disease away: It minimizes many diseases if the water is pure.
• They are furthermore saving water, additives, electricity & energy. They also decrease labor expenses.

Different water treatment systems

Boiler feedwater treatment systems:

Industries use boiler feedwater treatment systems to avoid damage to the boiler unit and piping components. They safeguard equipment from pollutants in the boiler and make up feeds. Boiler feedwater may cause scaling, corrosion, and fouling of the boiler and downstream equipment without proper treatment. This can result in costly maintenance, increased consumption of fuel, and failure of the boiler. Before entering the boiler, an efficient boiler feedwater treatment system works to eliminate harmful impurities. Furthermore, they regulate the water’s acidity and conductivity.

A cooling tower water system

In order to protect cooling tower components from damage, industries use cooling tower water treatment systems. They protect pollutants in the feed water, circulation water, or blow-down water that are present. By eliminating harmful impurities, an efficient cooling tower water treatment system works.

Wastewater treatment

Wastewater treatment is a method that transforms wastewater into effluent from its unusable state. This can either go back to the water cycle or can be reused for another purpose with minimal environmental problems. Wastewater treatment efficiently filters the water that goes down our drains before releasing it back into the atmosphere. They are ideal for modifying toxic streams into filtered water that can be released adequately into treatment facilities or the environment.

A raw water treatment system

Raw water treatment systems are built around particular objectives and applications for treatment. Therefore, from one installation to the next, the procedure can differ. Industries use it during pre-treatment and optimized for feed water. This is to increase manufacturing performance and process efficiency. Raw water treatment is a system composed of many individual technologies. They address your particular needs for the treatment of raw water.

Conclusion

There is a strong need for such water treatment in industries. This is because a lack of adequate water treatment can lead to a wide range of problems. In order to meet tight quality requirements, raw water entering an industrial plant also needs treatment. In order to make it safe for reusing or disposal, the used water often requires treatment. Some of the benefits of industrial water treatment are:

• Reduced cost 
• Operation excellence
• Reducing waste 
• Increased savings

So, from the above all points, it’s clear that industrial water requirement is much needed. As minerals can also build up in industrial equipment, causing scaling. This decreases their energy efficiency and performance, contributing to the cost of operations.

Cooling tower water treatment is a method to drain out harmful contaminants from your cooling tower feed water. In industrial processes, cooling is accomplished by means of various mechanisms requiring different equipment. The most widely used industrial cooling system is the use of a cooling tower. The specific configuration of your system depends on the following:

• What sort of cooling tower you have
• Manufacture-recommended standard criteria for cooling towers and equipment
• Chemistry in the circulatory water
• Regulatory criteria for discharge
• If blowdown is treated for reuse in the cooling tower
• The heat exchanger form
• Concentration period

Cooling tower operating conditions, including temperature, scale, flow, construction metals, and process variation, are different for each customer. We are leading the industry in developing the most robust and reliable solutions for cooling tower water treatment.

How is the Cooling Tower used in industries?

Cooling towers dissipate heat from recirculating water to ambient air. Heat is releasing out from cooling towers to the atmosphere via the evaporation process. As a consequence, the cooling towers also use large quantities of water by design. Water treatment for cooling towers is an integral part of process operations in many industries. However, it is to reduce water loss and eliminate zinc, chromates, and carbonate from the water used in the cooling towers.

Industries use cooling towers to preserve heat transfer surfaces and also to enable process heat removal and product throughput. Cooling towers are for comfort cooling in industrial or building applications. Water from cooling tower systems collects and consumes airborne pollutants continuously. It also leads to the excessive generation of deposits. These deposits contribute to a decrease in the efficiency of heat transfer and an increase in operational and maintenance costs. To ensure effective operation and long life, we also provide a wide range of filtration solutions to eliminate suspended solids and pollutants.

How is the cooling tower water treatment system working?

The proper treatment of cooling tower water is necessary to keep output running smoothly and prevent costly damage to cooling tower equipment. Standard cooling tower water treatment systems will typically include the following steps:

Cooling tower makeup water intake: 

Makeup water from the cooling tower is drawn from its source, raw water, city water, or other surface water source. Treatment is executing, depending on the quality of this water. If required, it would generally remove hardness and silica or stabilize and change the pH. The proper treatment optimizes the evaporation period of the tower and moreover minimizes the bleed rate of the water.

Filtration and Ultrafiltration:

In the next step, we run the cooling tower water through a different type of filtration process to eliminate any suspended particles. Removal of suspended solids upstream can also help protect membranes and ion exchange resins from polluting in the pre-treatment process. Depending on the filtration method, the suspended particles may be removed to less than one micron.

Ion exchange or water softening

If your makeup water has a high hardness, treatment can be used to remove the hardness. A softening resin with an extreme acid cation exchange process may be used. The resin is imposing with a sodium ion and has a higher affinity to calcium, magnesium, and iron as the hardness moves through it. So they will catch the molecule and release the sodium molecule into the water. These contaminants cause scale and also rust if it’s present.

Chemical addition:

Usually, this method requires the use of chemicals, such as:

• Corrosion inhibitors designed to neutralize acidity and protect metal components
• Algaecides and biocide to reduce microbial and biofilm growth
• Scaling inhibitors to prevent pollutants from forming scale deposits.

By treatment before this stage will help to reduce the number of chemicals required to treat water.

Side-stream filtering:

If cooling tower water is recirculating in the system, use a side-stream filtering unit to eliminate any pollutants entered by drift contamination. If the cooling tower water treatment system needs side-stream filtration, approximately 10% of the flowing water would be filtered through. It usually consists of high-quality multimedia filtration devices.

Blowdown Treatment:

The last phase of treatment needed for cooling tower water is blowing or bleeding from the tower. Blowdown is the flushing of a part of the high mineral content of cooling tower system water into the drain and replacing it with fresh water. This method dilutes the system’s mineral water concentrations, which are gradually rising due to water evaporation.

Depending on the quantity of water needed, the cooling plant also requires to circulate for proper cooling power; the plants will want to recycle and recover their water. Some post-treatment achieves this in the form of reverse osmosis or ion exchange. This helps liquids and solid waste concentrate and dispose of, while the processed water will be flowing back to the tower and is reused.
