About the Wastewater
Paint, Resin, Emulsion & Coating manufacturing units generate effluents containing pigments, solvents, polymers, acrylic emulsions, VOC, oil, suspended solids, and high COD/BOD. RRR ENVIRO SYSTEMS designs specialized ETP solutions ensuring compliance with TNPCB / CPCB norms and reuse standards.
Typical Pollutants in Paint Industry Effluent
- High COD & BOD load (2000 – 8000 mg/L)
- Paint sludge, pigments & suspended solids
- Solvents (Toluene, Xylene, MEK, IPA, etc.)
- Resins, emulsions, binders, acrylics
- Heavy metals (Lead, Zinc, Chromium, Titanium)
- Oil & Grease, Surfactants, Additives
- High color & turbidity
- Volatile Organic Compounds (VOC)
ETP Treatment Process Flow
