Effluent Treatment Plant

Product Description

An Effluent Treatment Plant (ETP) is a wastewater treatment system designed to remove contaminants from industrial effluents before discharging them into the environment or reusing them. It ensures compliance with pollution control norms and reduces environmental impact. --- Stages of an Effluent Treatment Plant 1. Preliminary Treatment Screening a Removes large solids like plastics, paper, and debris. Oil & Grease Removal a Separates floating oils and fats using skimmers. Equalization Tank a Balances variations in flow and pollutant concentration. 2. Primary Treatment Coagulation & Flocculation a Chemicals like alum or ferric chloride are added to aggregate small particles. Primary Sedimentation a Heavy solids settle at the bottom as sludge, while clarified water moves to the next stage. 3. Secondary (Biological) Treatment Aerobic Treatment (for organic waste): Activated Sludge Process (ASP) Moving Bed Biofilm Reactor (MBBR) Membrane Bioreactor (MBR) Sequential Batch Reactor (SBR) Anaerobic Treatment (for high-strength organic waste): Upflow Anaerobic Sludge Blanket (UASB) Anaerobic Digestion 4. Tertiary Treatment Filtration a Sand filters, activated carbon filters, or ultrafiltration remove fine particles and residual organics. Disinfection a Chlorination, UV treatment, or ozonation to kill pathogens. Reverse Osmosis (RO) a Used in Zero Liquid Discharge (ZLD) plants to recover water. 5. Sludge Treatment & Disposal Dewatering a Using filter presses or centrifuges. Sludge Drying Beds a For volume reduction before disposal or reuse as manure or biofuel. --- Applications of ETPs Textile & Dyeing Industries Food & Beverage Processing Pharmaceutical & Chemical Plants Paper & Pulp Mills Automobile & Metal Processing Units Hotels & Hospitals Would you like help designing an ETP for a specific industry, or are you looking for components like pumps, clarifiers, or filters?
