Types of Wastewater & Advantages of Treated Water

Types of wastewater

Overview

Wastewater is recycled into drinking water and this blog mention types of wastewater & the advantages of treated water. Since wastewater treatment is so entwining with other water uses, we classify it as water use. If wastewater is not adequately regulating, it can have a detrimental effect on the environment and human health. Water that is safe to drink is a vital life resource. It is necessary for the continued existence of life on this planet. Water contamination, on the other hand, is a significant threat. The fact that not everyone in the world has access to safe drinking water is an unfair reality. Mineral impurities or microbial and bacterial growth are commonly present in water, which can cause a variety of diseases.

Every year, water pollution and the diseases it causes claim the lives of many people around the world. Sewage treatment plants, effluent treatment plants, and wastewater treatment have become essential as a result of this. The primary goal of wastewater treatment is to eliminate as many dissolved solids as possible before releasing the residual water, known as effluent, into the atmosphere.

What is wastewater, exactly? Any used water that has been impacted by domestic, commercial, or industrial activities is referred to as wastewater.

The Four Types of Wastewater Treatment Systems

There are mainly four types of wastewater treatment systems. We’ll go through the various types of sewage treatment systems and other wastewater treatment solutions, as well as how they handle various types of wastewater below:

STP:

Remove the contaminants from wastewater at sewage treatment plants. This type of STP is vital for keeping residents safe and secure. Until discharging their wastewater into the system, they clean it with a mixture of physical, chemical, and biological treatment. When wastewater arrives at a sewage treatment facility, it is first filtered. It passes through screens and into settlement basins, where debris can be sluiced out. Debris is extremely damaging to an STP’s tanks and facilities. As a result, it’s important to extract as much dirt, gravel, and sand as possible from the wastewater. Many STPs are classified as three-stage because they handle wastewater in three stages: primary, secondary, and tertiary. 

ETP:

Sewage treatment plants, as we’ve seen, mainly handle municipal and domestic wastewater as the first step in the treatment process. On the other side, effluent treatment plants normally clean industrial wastewater. They deal with industrial effluent, which is wastewater that is generated as a byproduct of these businesses. We often use ETP in industries where there is a high risk of extensive chemical pollution in wastewater, such as pharmaceutical manufacturing and chemical industries such as textile and dye manufacturing. Plants are unable to release these chemical pollutants into the atmosphere until they have been appropriately treated. ETPs, like STPs, usually handle wastewater in four stages: preliminary, primary, secondary, and tertiary.

ETPs are advantageous for large operations, but they can be challenging to implement for smaller ones. They are massive and costly to construct and maintain, and they often necessitate the use of skilled technicians for operations and maintenance. While more extensive facilities can quickly meet these demands, smaller facilities must search for other options.

Activated sludge plant:

Activates sludge plants that handle activated sludge are similar to sewage treatment plants. They use activated sludge to digest biological pollutants in sewage wastewater. While we can use activated sludge as a secondary treatment in STP, it plays a more prominent role in an ASP. We use dissolved oxygen in activated sludge processes to facilitate the growth of biological flocs, which are clumps of organic matter. After that, the biological flocs assist in the breakdown of toxins in the wastewater. They capture particulates and clean wastewater by converting ammonia to nitrites and nitrates, which will be converting to harmless nitrogen gas. The construction of ASPs differs slightly from that of regular STPs. Most STPs have a primary settlement chamber that we must empty on a regular basis. They are frequently useful in situations where ease, cost-effectiveness, and simplicity are essential.

Common and Combined Effluent Treatment Plants (CETP):

Smaller wastewater generators may use common and combined effluent treatment plants to handle their waste. They lack the financial resources to properly manage and run these massive, complex systems. CETP provides a solution to this issue. CETP enables several wastewater-generating facilities in an industrial cluster to pool their effluent for treatment in a centralized facility. The costs of maintaining and running the CETP are shared by all the small facilities that send their wastewater to it. In exchange, they receive clean, compliant wastewater without having to operate several full-scale plants.

What Are the Different Types of Wastewater?

Any water that has been using is referred to as wastewater. For example, toilet water, industrial water, or rainwater that has run off into sewage. We must treat all of these by a wastewater treatment plant to remove pollutants. Moreover, they allow reusing the water. We can divide wastewater into three categories:

  1. Domestic wastewater: Domestic wastewater is wastewater that will be produced in a home.
  2. Municipal wastewater: Municipal wastewater is wastewater which we collect from homes, offices, shopping malls, restaurants, and other similar establishments in urban areas.
  3. Industrial wastewater: We make industrial wastewater from wastewater generated by industries, manufacturing and processing plants, etc.

What is the Impact of Wastewater Treatment on the Environment?

Protect Marine Life:

Wastewater treatment has a significant environmental benefit. Every year, around 1.2 trillion gallons of waste from homes and other sources will be pumping into its oceans. Contamination of this magnitude is dangerous to both marine life and humans. 

Rejuvenate Ground Water Tables:

Due to groundwater depletion, various parts of the world are experiencing extreme water shortages. If water can be released into these terrains after being pumped by a wastewater treatment plant, the underground water tables can be saturated. In certain places, this could solve the issue of water shortage.

Aquaculture/Fisheries & Tourism:

Aquaculture seriously harms many cases due to the discharge of untreated wastewater into marine environments. This is a danger not only to the aquaculture and fishing industry but also to the people who eat the fish. Untreated wastewater contains toxins that cause odor in water bodies. People are exposed to unsafe water laced with chemicals by tourism industries that operate boats in such bodies of water. The alternative is to use wastewater treatment plants to filter the wastewater. As a result, wastewater management is essential for human life, the atmosphere, and the entire ecosystem.
