Electroplating & Steel Industry Wastewater Treatment Solutions
Protecting people, plants, and the planet — advanced effluent treatment engineered for the unique demands of electroplating and steel processing units.
Engineered for One of Industry's Toughest Effluents
Electroplating and steel processing units generate some of the most complex and regulated wastewater streams in Indian manufacturing. From heavy metal-laden rinse water to acidic pickling liquors and oil-bearing cooling discharge, these effluents demand precision-engineered treatment — not off-the-shelf solutions.
At CH Four Energy Solutions, we design, install, and maintain Effluent Treatment Plants (ETPs) purpose-built for electroplating and steel facilities, helping units in and around Pune meet Maharashtra Pollution Control Board (MPCB) and CPCB discharge norms while safeguarding equipment, workers, and downstream water bodies.

Why Electroplating & Steel Effluent Needs Specialized Treatment
Electroplating and steel operations bring together a mix of contaminants that general-purpose treatment systems aren’t built to handle:
Heavy metals — chromium (hexavalent & trivalent), nickel, zinc, copper, cadmium, and iron from plating baths and rinse tanks
Cyanide compounds — from cyanide-based plating processes, requiring dedicated destruction before further treatment
Highly acidic or alkaline streams — from pickling, degreasing, and surface preparation stages
Oil & grease — from rolling, forging, and lubrication processes in steel units
High TDS & dissolved solids — from rinse water and process bleed streams
Suspended solids & scale — from descaling and mechanical processing
Left untreated, these contaminants pose serious environmental, regulatory, and operational risks — including corrosion of infrastructure, soil and groundwater contamination, and heavy penalties for non-compliance.
CH Four Approach to Electroplating & Steel Wastewater
We build treatment systems around the specific chemistry of your effluent stream, combining proven processes with continuous monitoring for consistent compliance.
Chromium & Heavy Metal Reduction
Chemical reduction of hexavalent chromium (Cr⁶⁺) to trivalent chromium (Cr³⁺), followed by precipitation and separation of nickel, zinc, copper, and other dissolved metals — recovering value where possible and ensuring safe discharge or reuse.
Cyanide Destruction
Controlled oxidation processes to safely break down cyanide compounds before the effluent proceeds to further treatment stages, protecting both plant safety and receiving water bodies.
Neutralization & pH Correction
Dedicated neutralization systems to handle the sharp pH swings typical of pickling baths, acid dips, and alkaline cleaning stages.
Physico-Chemical & Clarification Systems
Coagulation, flocculation, and clarification stages to remove suspended solids, oil, grease, and precipitated metal sludge efficiently.
Advanced Filtration & Membrane Systems
Ultrafiltration (UF) and Reverse Osmosis (RO) systems for polishing treated effluent, enabling water recovery and reuse within the plant — reducing freshwater intake and discharge volumes.
Cyanide Destruction
For units targeting zero effluent discharge, we design ZLD systems that recover usable water and concentrate residual salts for safe disposal — ideal for water-stressed industrial zones and units under strict MPCB norms.
Zero Liquid Discharge (ZLD)
Dewatering and safe handling of metal hydroxide sludge generated during treatment, in line with hazardous waste handling guidelines.
