Industrial Effluent Treatment Plant (ETP) Manufacturer in Pune
High-Performance Effluent Treatment Plant (ETP) Manufacturer in Pune
Industrial manufacturing facilities operating across Maharashtra’s heavy engineering belts—including Chakan MIDC, Bhosari, Ranjangaon, Talegaon, and Kurkumbh—handle some of the most aggressive and chemically challenging industrial effluents in India. Electroplating rinses, automotive phosphating baths, chemical synthesis mother liquors, and textile dyes generate wastewater laden with toxic heavy metals (hexavalent chromium, nickel, zinc), extreme pH swings (pH 1.0 to 13.0), emulsified cutting fluids, and refractory Chemical Oxygen Demand (COD) often exceeding 10,000 to 50,000 mg/L.
When industrial plants rely on sub-standard or undersized ETP systems, the results are catastrophic. Heavy metals pass straight through unprecipitated, biological aeration systems are poisoned and killed instantly by toxic chemical shocks, and clarifiers spew black, turbid effluent.
The regulatory consequences are swift and severe: the Maharashtra Pollution Control Board (MPCB) actively monitors industrial zones through surprise vigilance visits and online continuous effluent monitoring systems (OCEMS). Non-compliance results in immediate Section 33A closure directions, mandatory bank guarantee forfeiture, disconnection of water and electricity supplies, and prosecution under environmental protection statutes.

Frequently Asked Questions (High-Value Technical & Commercial Answers)
The most common reasons for ETP failure include: (1) improper chemical dosing due to reliance on manual estimation rather than automated pH/ORP sensors; (2) biological sludge poisoning caused by unsegregated toxic heavy metals or solvent dumps; (3) undersized clarifiers leading to solid carryover; and (4) poor maintenance of filter presses resulting in sludge accumulation inside settling tanks. TMS eliminates these issues through automated sensor-driven dosing, stream segregation, and fail-safe clariflocculation engineering.
We deploy dedicated chemical segregation and reduction circuits. For hexavalent chromium (Cr6+), effluent is acidified to pH 2.0–2.5, where sodium metabisulfite (SMBS) reduces it to trivalent chromium (Cr3+). The stream is then neutralized with lime/caustic to pH 8.5–9.2, precipitating chromium, nickel, zinc, and copper as dense, insoluble metal hydroxide sludges that are filtered through high-pressure plate-and-frame filter presses, leaving clear supernatant with heavy metal concentrations < 0.1 mg/L.
An ETP Adequacy Report is a comprehensive technical evaluation certified by a recognized environmental engineering institution or consultant confirming that your ETP design, hydraulic capacity, reaction retention times, and equipment sizing are technically capable of treating your factory's effluent to prescribed MPCB standards. TMS provides certified adequacy assessments backed by AISSMS engineering credentials, streamlining Consent to Establish (CTE) and Consent to Operate (CTO) renewals.
By utilizing high-rate lamella plate clarifiers and compact multi-disc dewatering presses rather than conventional civil settling tanks, TMS reduces the physical footprint of industrial ETPs by 50% to 65%. A 50 KLD heavy-duty physico-chemical ETP skid can be installed within a compact footprint of just 450 to 750 square feet.
Yes. By coupling your primary and secondary ETP with our tertiary filtration, ultrafiltration (UF), and Reverse Osmosis (RO) systems, we can recover 70% to 85% of industrial effluent as demineralized permeate water suitable for rinse baths, cooling towers, and boiler feed, significantly cutting freshwater consumption.
