No two industries send us the same water.

Municipal & Government

Green Enviro delivers decentralized sewage treatment plant solutions for municipal bodies, urban local bodies and government institutions, engineered for reliable public sanitation.

Power

Cooling towers alone can account for around 90% of a power facility's total water demand, and the water quality feeding a boiler has to be nearly mineral-free.

Paper & Pulp

Chlorine bleaching reacts with lignin to form AOX, adsorbable organic halides, a class of toxic, persistent compounds. Generic effluent treatment falls short here.

Automobile & Engineering

Even a few parts per million of oil can cause a treatment plant to fail if it is not removed at the right stage. Automotive and engineering wastewater rarely carries free-floating oil alone, most of it arrives emulsified, which changes what actually has to happen first.

Cement

Cement wastewater is largely inorganic and homogeneous. Kiln dust slurry and cooling blowdown carry real pH and suspended solids that need treating.

Chemical Industry

Green Enviro engineers ETP and ZLD systems for chemical manufacturers, handling variable pH, heavy metals and toxic compounds to meet CPCB and SPCB norms.

Schools & Educational Institutions

Green Enviro designs compact sewage treatment plants for schools, colleges and campuses, sized for academic-calendar occupancy swings and reuse in landscaping.

Food & Beverage

Green Enviro engineers anaerobic and aerobic treatment systems for food processing and beverage units, handling high-BOD organic load and FOG for compliant discharge.

Glass Manufacturing

Glass wastewater carries fine, abrasive glass particulate that keeps grinding equipment even after it leaves the production floor.

Hospitals & Healthcare

Green Enviro engineers STP and ETP systems for hospitals, addressing pathogen control, pharmaceutical residue and biomedical wastewater compliance requirements.

Hotels & Hospitality

Green Enviro engineers silent, odor-controlled sewage treatment plants for hotels and resorts, built for guest comfort alongside compliance and water reuse.

Mining

When sulfide-bearing rock meets air and water, it produces sulfuric acid on its own. Acid mine drainage is a naturally occurring problem that mining operations have to engineer around every single day.

Paint

Paint solids do not settle out politely like most suspended matter. Solvent-based paint residue is genuinely sticky and must be chemically detackified before filtration.

Paper & Pulp

Petrochemical

Unlike oil refining, petrochemical wastewater usually arrives largely free of oil and suspended solids. What makes it harder is a far wider range of biologically recalcitrant compounds.

Pharmaceutical

Green Enviro engineers advanced oxidation and ZLD-integrated treatment systems for pharmaceutical and API manufacturers, handling high-COD, solvent-heavy wastewater.

Residential Societies & Townships

Green Enviro designs sewage treatment plants for residential societies and townships, sized for occupancy surges and built for reliable RWA-managed operation.

Refinery

Oil in refinery wastewater shows up in three distinct forms, free, emulsified and dissolved, and each one needs a completely different removal method.

Rubber

Processing one ton of natural rubber generates 20 to 35 cubic meters of wastewater, and ammonia added to stabilize latex creates high nitrogen levels.

Solar Energy

94% of India's installed solar capacity sits in medium to high water-risk zones, and every panel still needs 3 to 5 liters of clean water for a proper weekly wash.

Steel

Steel manufacturing can consume anywhere from 2 to 20 cubic meters of water per ton of steel produced, and what comes back out carries heavy metals, oil, scale and acid residue that each need a different removal approach.

Sugar & Distillery

Distillery spent wash carries BOD as high as 45,000 to 60,000 mg/L, roughly a thousand times stronger than typical domestic sewage, and CPCB classifies alcohol distilleries as a Red category industry as a direct result.

Textile & Dyeing

Green Enviro engineers color removal, ZLD and water recycling systems for textile and dyeing mills, built around the specific chemistry of dye house effluent.

Thermal Power

Indian coal carries 30 to 45% ash content, far above international grades. Flue Gas Desulphurisation (FGD) systems add a completely new wastewater stream requiring dedicated treatment.
