How a Sewage Treatment Plant (STP) Works and Its Benefits

A Sewage Treatment Plant (STP) is a system that cleans wastewater from homes, buildings, and industries. It removes harmful germs and impurities from sewage so water can be safely reused or released into the environment.

This system is designed by analysing several factors such as daily water consumption, wastewater generation, site conditions, treatment capacity, and local environmental regulations.

In this blog, we will discuss STP plant working process, the importance of the Wastewater treatment plant, and more that help to design STP plant.
What Is Sewage Treatment Plant?
For cleaning the wastewater that is generated from homes and commercial buildings, STP (Sewage Treatment Plant) is a good option.

An STP Plant treats sewage and domestic wastewater from toilets, sinks, and washing machines. It removes harmful germs and impurities from the water, which make it safe for reuse in non-drinking purposes.
STP Plant Working Process for Wastewater Treatment
The STP wastewater treatment process cleans and recycles wastewater for safe reuse.
Wastewater first passes through bar screens to remove large solid waste.
An oil and grease trap removes floating oils and grease.
Air is added in the equalization tank to mix sewage properly and prevent sludge from settling.
Wastewater then enters MBBR tanks, where bacteria break down organic waste based on the BOD load.
The tube settler tank helps solid particles settle quickly, making the water clearer.
Clean water is stored in a filter feed tank for filtration.
Filters remove remaining solids, colour, and odour from the water.
Chlorination is done in the final stage to disinfect the treated water.
After disinfection, the water is safe for reuse in gardening, flushing, and other non-drinking purposes.
Benefits of Sewage Treatment Plants
There are many benefits of Sewage Treatment Plants, such as reducing fresh water demand, protecting the environment, control smells and more.
