Effluent Treatment Plant (ETP):
Collection Tank: Commencing part, waste from different section enter here.
Storage Tank: Several blower pipe in this chamber. Mixing properties are different with temp. as well.
Mixing & Cooling: Cooling tower is on paddle mixer used for mixing.
Neutralization: PH is controlled here.
Chemical Coagulation: Fe₂(SO₄)₃, Al₂(SO₄)₃ etc use for coagulation.
Biological Oxidation Tank: Artificially Eco-system established. Blowing air helps to live micro-organism.
Sedimentation & Separation of Sludge: The blanket of precipitations is skimmed off to another tank and remaining solution is removed to pressure filter.
Sludge Thickener: After exceeding the required level of recycling, sludge passed through thickening chamber.
Filtration: Filtration layer consists of sand rock which filter wet sludge to extract water rest in it.
Discharge to Drain: Release to environment with the check of final load of effluent in it.
Industries through waste liquor into rivers, canals etc. Before flowing this liquid to outwards, the plant which treats this effluent to a harmless form for the environment is known as Effluent Treatment Plant (ETP).
