ETP Manufacturer & Supplier — Visakhapatnam (Vizag), Andhra Pradesh
Turnkey effluent treatment plants for Visakhapatnam's pharmaceutical, steel, refinery, and chemical manufacturers — APPCB-compliant ETP, ZLD, and pre-treatment systems for Parawada Pharma City, VSEZ, and Vizag's industrial corridors
Industry Overview
ETP Manufacturer & Supplier — Visakhapatnam (Vizag), Andhra Pradesh
Visakhapatnam (Vizag) is Andhra Pradesh's largest city and one of India's most important industrial and port cities, with a unique concentration of heavy industry, petrochemicals, pharmaceuticals, and port-based manufacturing. RINL/Vizag Steel — one of India's largest integrated steel plants — dominates the northern industrial zone. HPCL's Visakh Refinery processes over 8.33 MMTPA of crude oil, making it one of India's significant refineries. The Parawada area, 25 km from the city, hosts Jawaharlal Nehru Pharma City — one of India's largest pharmaceutical SEZs with over 200 API and formulation manufacturers. The Visakhapatnam Special Economic Zone (VSEZ) adds chemicals, electronics, and manufacturing to the city's industrial profile.
Andhra Pradesh Pollution Control Board (APPCB) enforces strict environmental compliance across Visakhapatnam's diverse industrial base. Proximity to the Bay of Bengal coastline and ecologically sensitive areas heightens the importance of treated effluent quality — marine environment standards are stricter than inland discharge norms in many respects. The Parawada Pharma City CETP handles combined pharmaceutical effluent, but individual unit pre-treatment is mandatory. APPCB has been particularly active in enforcing OCEMS requirements for Vizag's heavy industry — steel, refinery, and chemical units face continuous monitoring obligations under CPCB directives for red-category industries.
Spans Envirotech delivers industrial ETP and ZLD EPC projects across India. Our pharmaceutical ETP expertise — handling API residues, solvents, and bioactive compounds — combined with experience in heavy industrial effluent treatment makes us well-suited to Visakhapatnam's industrial profile. We provide APPCB consent documentation support, process design, equipment supply, civil coordination, commissioning, and post-commissioning AMC for ETP and ZLD projects across Vizag and Andhra Pradesh.
Industry Challenges
Key Environmental Challenges
Pharmaceutical API Effluent — Parawada Pharma City
Parawada's API and bulk drug manufacturers discharge highly variable, complex organic effluent with pharmaceutical intermediates, solvents, and antibiotic residues that inhibit conventional biological systems. Pre-treatment (solvent stripping, chemical oxidation) is essential before CETP connection, and units with incompatible streams require standalone ETPs. APPCB CTO conditions for pharma units include API-specific parameters and ZLD requirements for certain categories.
Steel Plant Effluent — Complex Multi-Stream
Integrated steel plant effluent includes coke oven gas wash water (with phenols, cyanide, ammonia, and PAHs), blast furnace cooling water, pickling acid effluent with heavy metals, and scale pit water with suspended solids and oil. Multi-stream pre-treatment before combined biological treatment is required — a highly complex ETP design challenge.
Refinery and Petrochemical Effluent
HPCL and ONGC refinery operations generate oily process water, desalter effluent with salt and emulsified oil, spent caustic, and cooling tower blowdown. API oil-water separators, DAF, biological treatment (bio-trickling filters or MBBR), and advanced polishing are required. Phenol and ammonia from refinery effluent require specific treatment stages.
Bay of Bengal Coastal Discharge Sensitivity
Visakhapatnam's coastal location means some industrial units discharge treated effluent to marine environment — where BOD, TSS, and oil standards are stringent. Coastal and port-based industries must meet marine discharge standards in addition to general APPCB limits. Any treated effluent to the Bay of Bengal requires highest-quality tertiary treatment.
OCEMS Requirements for Heavy Industry
CPCB mandates Online Continuous Effluent Monitoring Systems (OCEMS) for Vizag's red-category heavy industries — steel, refinery, chemicals. OCEMS systems must transmit pH, flow, BOD, COD, TSS, and other parameters to CPCB servers continuously. ETP systems must be instrumented and automation-ready to support OCEMS compliance.
Our Solutions
Tailored Wastewater Treatment Solutions
Pharmaceutical ETP and CETP Pre-Treatment — Parawada
Multi-stage ETPs and CETP-compatible pre-treatment systems for Parawada pharma manufacturers — solvent stripping, chemical oxidation, biological oxidation, activated carbon polishing. Standalone ZLD systems for units with high-solvent or incompatible effluent streams that cannot connect to CETP.
Steel Industry ETP — Multi-Stream Treatment
Integrated multi-stream ETPs for steel plant effluent — coke oven effluent treatment (phenol and cyanide removal, ammonia stripping, biological oxidation), acid pickling neutralisation and heavy metal removal, and combined effluent polishing. Designed to APPCB and CPCB standards for integrated steel plants.
Refinery and Petrochemical ETP
API oil-water separators, induced gas flotation (IGF/DAF), biological treatment for phenolics and organics, and advanced polishing (activated carbon, ozonation) for refinery and petrochemical effluent. Designed for APPCB and HPCL-OISD standards.
ZLD for Pharma and Mandated Industries
End-to-end ZLD systems for APPCB-mandated pharmaceutical and chemical units in Vizag — RO-based water recovery and MEE/MVR thermal evaporation for zero liquid discharge. Compliant with APPCB ZLD CTO conditions.
OCEMS Installation for Red-Category Industries
Online Continuous Effluent Monitoring System installation for Vizag's heavy industry — flow meters, multi-parameter sensors, data loggers, and CPCB server connectivity. Reduces compliance risk from continuous monitoring gaps.
Port and Harbour ETP Solutions
Bilge water treatment, ship repair effluent treatment, and marine environment-compliant ETPs for port and harbour operations in Visakhapatnam. Systems designed to meet coastal and marine discharge standards.
