An ETP treats process effluent from manufacturing operations — pharma, automotive, food & beverage, chemicals, electroplating — before discharge or reuse. Our ETPs are designed to clear CPCB / SPCB consent norms with margin, and to keep clearing them after the first chemistry change, the second operator turnover, and the third audit.
Industrial effluent is rarely a single thing. It's a fluctuating cocktail of organic load (BOD/COD), suspended solids, dissolved salts, oils, surfactants, heavy metals and trace contaminants — each requiring different treatment chemistry.
An ETP processes that mixture through a deliberate sequence of physical, chemical and biological steps — each stage handing the next a slightly cleaner stream — until the output meets the discharge standard your consent stipulates, or the reuse target your closed loop demands.
The difference between a good ETP and a bad one is rarely visible at commissioning. It shows up at year three, when load profiles drift, monsoon flow surges through, and the operator who tuned the chemistry has moved on. Our ETPs are designed for that year-three test, not the day-one ribbon-cutting.
Bar screens, grit removal, oil & grease separation, equalisation tank — buffers flow and load variations across shifts and product changes.
Chemical dosing, flocculation, primary clarification or DAF — removes coarse suspended solids, FOG and the easy fraction of organics.
Biological treatment — ASP, MBBR, MBR or SBR — for BOD/COD reduction. The heart of any ETP and where most failures hide.
Polishing — sand filtration, ACF, UF, disinfection. Output meets discharge consent or reuse specification.
From compact pre-fabricated units for SMEs to large custom-engineered plants for production facilities. Skid-mounted or civil-built.
We pick the biological technology that suits your effluent, footprint, capex/opex and operator availability — not the one that gives us best margin.
Designed to meet, with margin, the discharge norms applicable to your industry vertical, zone classification and consent conditions.
Solvent-laden, high-COD effluent. Sectoral ZLD mandates apply across most of the corridor; FDA-grade documentation expected.
Oily runoff, paint shop effluent, ED-bath waste. Each stream typically has dedicated pre-treatment before joining the main ETP.
High-COD, FOG-laden. Biological-heavy treatment with DAF / UASB / MBBR cores; CIP shocks must be absorbed.
Variable batch chemistry. Equalisation, biology buffering and ZLD redundancy are essential — not optional.
Heavy metals, cyanides. Chemical destruction and metal precipitation come before any biological treatment can begin.
Salinity-rich and colour-bearing. Often paired with ZLD recovery for compliance and salt recovery economics.
