ETP Manufacturer & Supplier — Kochi (Cochin), Kerala
Turnkey effluent treatment plants for Kochi's seafood processing, chemicals, rubber, food manufacturing, and commercial sectors — KSPCB-compliant ETP, ZLD, and STP systems for Kochi and Kerala's industrial estates and backwater-sensitive environment
Industry Overview
ETP Manufacturer & Supplier — Kochi (Cochin), Kerala
Kochi (Cochin) is Kerala's commercial capital and one of India's most strategically important port cities, home to Cochin Port — one of India's largest natural harbours. The city's industrial base is distinctive — anchored by seafood processing and exports, chemicals and fertilisers, petroleum refining, rubber processing, and a growing hospitality and IT sector. Cochin Fisheries Harbour is one of India's largest seafood export hubs, with hundreds of processing units exporting shrimp, fish, and cephalopods to EU, USA, and Japan. FACT (Fertilisers and Chemicals Travancore) at Udyogamandal is one of India's oldest fertiliser producers. BPCL's Kochi Refinery processes over 15.5 MMTPA of crude, making it one of the largest refineries in India. Cochin Shipyard Limited (CSL) — India's largest shipyard — operates ship repair and new construction in Kochi.
Kerala State Pollution Control Board (KSPCB) enforces environmental compliance across Kochi's diverse industrial base, with particular sensitivity to Kerala's unique ecosystem — the interconnected backwaters, estuaries, and coastal areas that are ecologically rich and culturally significant. Industrial discharge into backwater-connected drainage has serious consequences — KSPCB enforcement is rigorous, particularly for seafood processing, chemicals, and rubber units near water bodies. KSPCB's CTO conditions for Kochi industries often include backwater proximity standards stricter than general CPCB norms. Kerala's high literacy and environmental awareness also means industrial pollution incidents face strong community response.
Spans Envirotech provides turnkey ETP and STP EPC services across South India. Our food processing ETP experience — particularly the high-BOD, high-TSS characteristics of seafood and food processing effluent — combined with multi-sector capability covering chemical, rubber, and commercial STPs makes us well-suited to Kochi's industrial profile. We offer KSPCB consent documentation, process design, equipment supply, commissioning, and AMC for ongoing Kerala compliance.
Industry Challenges
Key Environmental Challenges
Seafood Processing High BOD and Odour
Fish and shrimp processing generates high-BOD wastewater (BOD 500–2,500 mg/L) with blood, fish solids, ice-melt, and cleaning chemicals — plus intense H₂S odour from putrefying organic matter. DAF for protein and fat removal, biological treatment, and dedicated odour control (biofilter or scrubber) are essential. Export units face international food safety standards that include wastewater management.
Backwater and Estuarine Sensitivity
Kochi's industries are often located near backwaters, canals, and estuarine systems. Discharge from ETPs must meet elevated standards to protect these ecologically sensitive areas. KSPCB imposes stricter consent conditions for industries near Vembanad Lake and Periyar river estuary — the primary water bodies around Kochi. Even treated effluent with marginal BOD can visibly affect backwater ecology.
Rubber Processing Effluent — BOD and Sulfide
Natural rubber latex processing generates high-BOD wastewater (BOD 2,000–6,000 mg/L) from latex concentration, acid coagulation, and sheet drying — plus sulfide and ammonia from latex preservation chemicals. Biological treatment (UASB + MBBR) with sulfide control is the standard approach. Kerala's rubber cooperative and small rubber processing units need cost-effective KSPCB-compliant ETPs.
Chemical and Fertiliser Complex Effluent
FACT and other chemical manufacturers in Udyogamandal generate ammonia-rich effluent from fertiliser production, acidic/alkaline process streams, and cooling tower blowdown. Multi-stream treatment with ammonia stripping, neutralisation, biological oxidation, and advanced polishing is required for KSPCB compliance.
STP for Kerala's Hospitality and Real Estate Boom
Kochi's booming hospitality sector — hotels, resorts, serviced apartments, IT parks — creates large STP demand. Kerala's KSPCB mandates STP installation for all hotels, resorts, and large commercial buildings. Treated water reuse for landscaping and flushing reduces freshwater demand in Kerala's premium real estate developments.
Our Solutions
Tailored Wastewater Treatment Solutions
Seafood Processing ETP — Kochi and Kerala
Purpose-designed ETPs for seafood and fish processing units — Dissolved Air Flotation for protein and fat removal, MBBR biological treatment for BOD reduction, dedicated odour control (biofilters or packed tower scrubbers), and sludge dewatering. Systems designed to meet KSPCB CTO conditions and international seafood export standards.
Rubber Processing ETP
ETPs for natural rubber and latex processing units — sulfide removal (chemical oxidation), UASB anaerobic pre-treatment for high-BOD latex effluent, MBBR polishing, and ammonia removal. Biogas recovery from UASB stage offsets processing energy costs.
Chemical and Fertiliser ETP
Multi-stage ETPs for chemical manufacturing and fertiliser production — ammonia stripping, neutralisation, biological oxidation (nitrification/denitrification), and advanced polishing. Designed for KSPCB CTO conditions for chemical and fertiliser effluent near backwaters.
Petroleum Refinery Effluent Treatment
API oil-water separators, Induced Gas Flotation, biological treatment for phenolics and organics, and tertiary polishing for BPCL and refinery-adjacent industries in Kochi. Designed to meet KSPCB and OISD standards for refinery effluent.
STP for Hospitality and Commercial Complexes
Compact MBBR and MBR-based STPs for Kochi's hotels, resorts, IT parks, and residential developments — designed for KSPCB STP norms and treated water reuse for landscaping, cooling, and flushing. Supporting LEED and IGBC green building certifications.
Odour Control Systems for Seafood and Food Processing
Dedicated H₂S and organic odour control systems for Kochi's seafood and food processing units — biofilters, packed tower scrubbers, and chemical dosing systems to manage odour from processing operations and ETP sludge handling areas.
