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
