Effluent Treatment Plant (ETP)

Effluent Treatment Plant (ETP)

An ETP is used to treat industrial wastewater (from factories like textile, pharma, chemical plants). It removes harmful chemicals, oils, heavy metals, etc., before discharge or reuse. 
⚙️ ETP Process Flow (Steps)
Typical stages:
Collection Tank – collects wastewater
Equalization Tank – balances flow and concentration
pH Adjustment – neutralizes acidic/alkaline water
Coagulation & Flocculation – chemicals added to form particles
Primary Clarifier – solids settle
Biological Treatment (Aeration) – bacteria break organic matter
Secondary Clarifier – sludge separation
Filtration & Disinfection – final cleaning
Sludge Drying – waste sludge treatment
