Effluent treatment Plant for Recycling Plastic Industry
Overview
Plastic recycling industries generate wastewater from washing, shredding, cleaning, separation, and recycling processes. The effluent typically contains suspended solids, plastic fines, oils & grease, detergents, organic contaminants, color, and high COD. An Effluent Treatment Plant (ETP) is designed to effectively treat and recycle wastewater, reduce freshwater consumption, and comply with environmental regulations.
Treatment Process Flow
Collection Tank → Equalization Tank → Oil & Grease Trap → Coagulation & Flocculation → Primary Clarifier / DAF System → Biological Treatment (MBBR/FBBR) → Secondary Clarifier → Pressure Sand Filter → Activated Carbon Filter → UF/RO System (Optional) → Water Reuse / Discharge
