Effluent treatment Plant for Electroplating Industry
Overview
Electroplating industries generate wastewater containing heavy metals, cyanides, acids, alkalis, oil & grease, suspended solids, and toxic chemicals. A specialized Effluent Treatment Plant (ETP) is designed to remove these contaminants, recover valuable metals, and ensure compliance with environmental regulations before discharge or reuse.
Treatment Process Flow
Collection Tank → Equalization Tank → pH Correction → Chrome Reduction System → Cyanide Oxidation System → Coagulation & Flocculation → Primary Clarifier → Pressure Sand Filter → Activated Carbon Filter → UF/RO System (Optional) → Treated Water Reuse/Discharge
