Effluent treatment Plant for Chemical Industry
Overview
Chemical industries generate complex wastewater containing high COD, BOD, TDS, suspended solids, acids, alkalis, oils, heavy metals, toxic organics, and color. An Effluent Treatment Plant (ETP) is designed to remove these contaminants and ensure compliance with environmental discharge norms while enabling water reuse and resource recovery.
Treatment Process Flow
Collection & Equalization → pH Correction → Coagulation & Flocculation → Primary Clarification → Biological Treatment (MBBR/FBBR/SBR/ASP) → Secondary Clarification → Pressure Sand Filter → Activated Carbon Filter → UF/RO System (Optional) → Treated Water Reuse/Discharge
