Effluent treatment Plant for Dairy Industry
Overview
Dairy industries generate wastewater from milk processing, equipment washing, pasteurization, CIP systems, packaging operations, and floor cleaning activities. The effluent typically contains high levels of organic matter, fats, oils & grease (FOG), proteins, lactose, suspended solids, and nutrients. An Effluent Treatment Plant (ETP) is designed to efficiently reduce pollution load, enable water reuse, and ensure compliance with environmental regulations.
Treatment Process Flow
Collection Tank → Equalization Tank → Oil & Grease Trap → pH Correction → DAF System → Biological Treatment (MBBR/FBBR/SBR) → Secondary Clarifier → Pressure Sand Filter → Activated Carbon Filter → UF/RO System (Optional) → Water Reuse / Discharge
