Sewage Treatment Plants operate to remove the harmful chemicals or the contaminants from the household wastewater so that the sewage released as a waste do not pose a threat to our already at-risk green planet. It is crucial to understand that these waste water cannot be minimised as they are a result of the normal human bio activities, but these need to be chemically treated to protect ourselves. If you own a sewage treatment plant or looking forward to set up one, consult the leading STP Plants manufacturer India to receive the genuine setup or its various parts. So if you own a sewage treatment plant, check below for all the details.

Origin– Generally the waste water produced from kitchens and bathrooms of both domestic and commercial buildings contribute to the maximum share of waste water. Also, faulty connections, bad weather giving way to overflowing polluted water from drains or canals, underground cracks in pipes are another source of the waste water.

From Sewage to Sewage Treatment Plants – Now, the question is how the sewage travels to the treatment plants! These plants have 3 sets of pipes. First, when the water is flushed or drainage of the waste water happens from domestic or commercial buildings, it reaches the local sewers which are managed by the local sewers team of the town. These local sewers transfer the sewage to interceptor sewers, ranging from 8 inches to 11 feet in diameter. These are then transferred to MWRA sewers. Generally, the sewage water travels through the pipes via gravity however some low or underground sewage and waste water in critical conditions might need pumping.

Functioning – There are generally two phases of treatment – primary and secondary, where the first phase of secondary treatment came to practice in July 1997. Below outlined is the detailed procedure of the treatment and management of waste water:

1. Firstly, the sewage is collected by getting them transferred over the pipes, after segregation of the wastewater. The pumps in the sewage treatment plants actually draw the sewage to the next level, and often they operate underground as required.
2. Now, the Preliminary Treatment takes place, where the mud and sand settle or weigh down in a grit chamber, a tank inside the treatment plant’s second stage. After treatment, this material is dumped safely on a landfill for safe disposal.
3. Now, the Primary Treatment occurs, where the sewage moves to the settling tanks wherein about 60 % of the solid and semi-solid components of the waste water weigh down in the form of a mixture of sludge and water. This stage removes toxic chemicals and contaminants but, not totally.
4. The final stage is the secondary treatment, wherein, oxygen is pumped into the waste water to promote the growth of micro-organisms. These microbes will consume the waste component and finally weigh down at the bottom of the secondary settling tanks. Once this stage is completed, about 80 – 90 % of the human waste and solid components are removed along with the harsh chemicals and contaminants.

The remaining sludge and water concoction is disinfected and processed further to remove the disease causing microbes and bacteria and finally disposed off.
