What We Do
Industrial Wastewater Treatment in India
Industrial wastewater treatment is the engineered process of removing contaminants — biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids, heavy metals, oils, and hazardous substances — from manufacturing process effluent before discharge or reuse.
India's Central Pollution Control Board (CPCB) and State PCBs mandate all Red, Orange, and Green Category industries to treat effluent to prescribed discharge standards. With increasing water scarcity and ESG compliance expectations from investors and buyers, effective wastewater treatment is now both a regulatory necessity and a competitive advantage.
Spans Envirotech has been designing, building, and commissioning industrial wastewater treatment plants since 1993 — across food & beverage, pharmaceuticals, textiles, sugar & distilleries, chemicals, dairy, and municipal sectors.
Regulatory Compliance
CPCB & SPCB discharge standards, Zero Liquid Discharge mandates for Red Category industries in water-stressed states.
Water Scarcity & Reuse
With groundwater depleting across India, treated effluent reuse can reduce freshwater consumption by 30–70%.
ESG & Sustainability
Global supply chains, export buyers, and institutional investors now audit environmental performance — treatment systems are essential.
Resource Recovery
High-strength effluent (sugar, dairy, food) can yield biogas for captive energy, reducing operational costs.

FAQ
Frequently Asked Questions
What is industrial wastewater treatment?
Industrial wastewater treatment removes contaminants — BOD, COD, TSS, heavy metals, oils, and hazardous chemicals — from process effluent generated by manufacturing facilities before discharge or reuse. It involves primary (physical), secondary (biological), and tertiary (advanced) treatment stages tailored to the specific industry.
Which industries need an ETP in India?
Under CPCB norms, all Red, Orange, and Green Category manufacturing industries must treat effluent. Key sectors include food & beverage, pharmaceuticals, textiles, sugar & distilleries, chemicals, dairy, paper, and steel. Red Category industries in 17 water-stressed states must achieve Zero Liquid Discharge.
What are the CPCB standards for industrial discharge?
CPCB General Standards require: pH 5.5–9.0, BOD ≤30 mg/L, COD ≤250 mg/L, TSS ≤100 mg/L, Oil & Grease ≤10 mg/L for discharge to inland surface waters. State PCBs may impose stricter limits. ZLD is mandated for certain industries.
What is the difference between ETP and STP?
ETP (Effluent Treatment Plant) treats high-strength industrial process wastewater with complex contaminants. STP (Sewage Treatment Plant) treats domestic sewage with lower, predictable organic strength. Large industrial sites need both.
What does a full industrial wastewater treatment project include?
Spans Envirotech provides: effluent characterisation & treatability study; process design & technology selection; detailed engineering; equipment procurement; civil & mechanical construction; commissioning & performance testing; operator training; and optional annual maintenance contracts.
