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.
