Growing urbanization and strict wastewater discharge regulations have made installing a Sewage Treatment Plant (STP Plant) essential for residential, commercial, and industrial projects. According to environmental norms issued by the Central Pollution Control Board, untreated sewage cannot be discharged into the environment.
Koshish India delivers high-performance, energy-efficient, and customized STP plant solutions in India designed to meet regulatory standards and support water reuse. If you are searching for “STP plant manufacturer in India,” “STP plant cost in India,” “commercial sewage treatment plant,” “industrial STP plant installation,” or “apartment STP plant supplier,” this detailed guide will provide complete information.
What is a Sewage Treatment Plant?
A Sewage Treatment Plant is a system designed to treat wastewater generated from households, offices, industries, and institutions. It removes:
Organic pollutants
Suspended solids
Oil and grease
Harmful microorganisms
Odor and color
After treatment, the water can be reused for:
Toilet flushing
Gardening
Cooling towers
Construction work
Industrial applications
The primary objective is to reduce BOD, COD, TSS, and pathogens to permissible limits.
STP Plant Working Process
The STP plant working system involves three main stages:
Primary Treatment
Removal of large solids through screening
Grit removal for sand and heavy particles
Sludge settling in clarifiers
Secondary Treatment
Aeration process for biological treatment
Microorganisms break down organic matter
Separation of treated water and sludge
Tertiary Treatment
Sand filtration
Carbon filtration
UV or chlorination disinfection
The treated water meets discharge norms and can be safely reused.
