The treatment train

What actually happens to the water

Every ETP/STP we build follows the same real sequence of physical, biological and chemical stages — sized and tuned to your effluent's characteristics.

01
Screening & Oil Trap
Removes solids, grit and free oil before treatment.
02
Equalization
Balances flow and load so downstream units run steady.
03
Aeration (Biological)
Microbes break down organic load, cutting BOD/COD.
04
Clarification
Settles biomass; clear water moves ahead.
05
Filtration
Pressure sand & carbon filters polish the water.
06
Disinfection & Reuse
Chlorination/UV; water is safe to discharge or reuse.
