In India, sewage treatment facilities are an essential element. They have greatly expanded their popularity as a result of their excellent service. Water Pollution is a serious part to be taken care of and the sewage plants ensure that they are working towards it. Various types of sewage treatment plants are now operating in the nation to treat the wastewater. Here, in this blog, we will tell you all the types of wastewater treatment facilities and how they operate.
Every kind of sewage treatment facility is designed to accomplish a certain task which is ultimately to provide the city with fresh and clean water. India now has a variety of approaches to deal with the problem of water contamination as a result of technical improvement. We are able to recycle sewage water just because of various treatment procedures, which also contribute to a healthy, toxin-free environment.
What is a Sewage Treatment Plant?
A sewage treatment plant, also known as a wastewater treatment plant, is a place where people’s toilets, washbasins and wastewater are cleaned. They are an essential component of the cleaning procedure that protects every person’s well-being and security in an area.
The majority of the time, sewage treatment facilities manage all of the wastewater from nearby residences and businesses. However, it is most suitable to separate the clean water from the sewer system.
When untreated wastewater enters the facility, it is treated using various tools and procedures. Before releasing the wastewater to an ocean or lake, the treatment facility strives to get rid of as many organisms and pollutants as it can.
Types of Sewage Treatments Plants in India
The wastewater treatment facilities all function in various ways and generate wastewater of different quality. Additionally, each type of sewage treatment plant modifies different quality of wastewater to varying degrees of effectiveness. Some can handle low loads while others don’t perform as well. While some plants are better able to handle heavier loadings, others aren’t prepared to treat large amounts of sewage efficiently. Let’s learn about all the types of wastewater treatment plants.
Rotating Disc System
Wastewater treatment facilities using rotating disc systems provide a dependable, strong alternative that produces an excellent amount of effluent. They can also be retrofitted to already-existing wastewater management systems and are appropriate for every kind of use. They have little environmental impact and cause little noise pollution, making them the perfect choice for populated locations.
Rotating disc systems, in contrast to some other kinds of wastewater treatment facilities, only need to be de-sludged once every twelve to eighteen months. Additionally, they do not need a full-time caretaker to perform any responsibilities. Here are some examples of the Rotating disc system that is used in various treatment plants:
- Tuke and Bell
- Klargester Biodisc
- Clearwater Rotoclear
Activated Sludge Plant – Best Types of Sewage Treatment Plants
An active sludge plant sometimes referred to as an Activated Sewage Plant or ASP, employs a wastewater treatment method that entails providing organic contaminants with oxygen and microbes. These bacteria are utilized in wastewater treatment to oxidize the contaminants, which ultimately results in the formation of a substance resembling sludge.
The sludge is then passed out to more tanks to remove the bacteria contamination in which UV radiations are passed along with the reverse osmosis process. Some common sewage treatment plants that use ASP technology include:
- Vortex
- Bison
- Biodigester
- Biopure

Submerged Aerated Filter (SAF)
SAFs, often referred to as submerged aerated filter systems, are a common sewage treatment option. These systems are easy to use, have few mechanical components and minimal upkeep is required. SAF is a viable alternative for businesses trying to cut costs without sacrificing the quality of their effluent. SAFs can be utilized for both industrial and home wastewater treatment and don’t require an ordinary caretaker to be around. Some common examples of submerged aerated filters used in treatment water plants include:
- Falcom
- Matrix
- Clearwater Aeroclear
Sequencing Batch Reactors
Sequencing batch reactors, commonly referred to as load and draw systems, use a series of processes for handling wastewater. The same tank reactor serves as the setting for each phase of the purification. These systems, which are incredibly adaptable, can handle a variety of sewage kinds, from weak to powerful and provide pure water at the end. Some common examples of wastewater plant that uses Sequencing batch reactors include:
- Argos
- Lakeside
- Fluidyne
Stages of Treating Sewage Water
Now if you have known all the common types of Sewage treatment plants, you must know how they work. Untreated wastewater is normally sanitized in three stages, regardless of the kind of wastewater treatment plant. Again, there may be minor differences from plant to plant, but these are typically the three stages of the wastewater treatment process:
Primary Treatment
This is the initial stage of the wastewater treatment process. Usually, this is accomplished by allowing the sewage to rest in a storage container for a while. As a result, the solid particles fall to the tank’s bottom. The sewage is subsequently moved to the second stage of the procedure, leaving its fragments behind. Most of the treatment facilities fit a motorized scraping in their tank which is able to collect more solid impurities and contaminants from sewage.
Secondary Treatment
Sewage is not given prolonged treatment as its primary treatment. The second phase is when this happens. The plant uses biofiltration, aeration, and oxidation ponds for the wastewater during this stage. As a result, the biological components in sewage naturally decay producing a waste product that is far safer when released into the water.
Tertiary Treatment
It is used to clean the wastewater and help it meet the demands of industry or the norms for discharging wastewater into the seawater. It meets the norms defined by the region where the sewage treatment plant is located. This is the last stage in the purification of water. This stage of sewage treatment includes purging the water so that it is safe to drink.
To Sum Up
All the types of sewage treatment plants work on the 3 basic stages of treatment. All the types can accommodate different extremity of water impurity, have different efficiency, require unique types of care and produce different levels of purified water according to usage. If you are thinking of installing a sewage plant in your locality or industry, it is suggested to take expert advice rather than assuming.
