Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release to the environment. A by-product of sewage treatment is a semi-solid waste or slurry, called sewage sludge. The sludge has to undergo further treatment before being suitable for disposal or application to land.

Various technologies of sewage treatment:

• 1. Activated Sludge Process.
• 2. Sequential Batch Reactor.
• 3. Moving Bed Bio-Reactor.
• 4. Membrane Bio-reactor.
• 5. Ultra Filtration. Etc

How many sewage treatment plants are there in India?

According to the studies conducted by Central Pollution Control Board (CPCB), there are 269 sewage treatment plants (STPs) of which 231 are operational in India. These 231 sewage treatment plants treat just 21% of the total sewage generated. The sewage treatment plant manufacturer are also developing more effective techniques to treat a large quantity of sewage.

Is there any code for STP design in India?

Yes, there is an Indian standard code of practice for the installation of septic tanks given by the Bureau of Indian Standards (1986). The code is designed to ensure that the sewage is treated in a way that maintains and hygiene of the community and its surrounding area. All sewage treatment plant manufacturer should follow the code.

The code has two parts

• 1. To meet design and construction criteria
• 2. To ensure safe treatment and disposal of septic tank effluent.

Genex is one of the leading sewage treatment plant manufacturer in Bangalore, we provide the plants of the above technologies ranging from KLD – MLD. Modular types of treatment plants can also provide for buildings having space concerns with SBR/MBBR/MBR technologies.

Effluent treatment plants helps in solving the environmental pollution problem created by the waste material of a company without exposing the same to the environment. The effluent treatment plants are designed to treat the effluent coming from different process of the plant. The treatment of different effluents varies with the type of effluent. The technologies used are same as the sewage treatment plants with the addition of the various chemicals for the effluent chemical retrieval.
