Every factory's effluent stream is different. We design ETPs from a laboratory characterisation of your actual stream — not a catalogue template — for engineering, food processing, pharmaceutical, textile, and chemical units.
Screening → equalisation and pH correction → physicochemical treatment → biological oxidation → tertiary polishing → sludge handling. Every stage sized from your effluent characterisation.
Screening removes coarse solids, oil and grease separation protects downstream process, and neutralisation brings pH within a workable range before chemical treatment begins.
Coagulation and flocculation destabilise suspended and colloidal matter; a tube settler or dissolved air flotation (DAF) unit removes the resulting floc — the workhorse stage for most industrial streams.
Where the organic load justifies it, a biological stage further reduces BOD/COD before the stream moves to polishing — sized from the effluent characterisation, not a standard template.
Pressure sand and activated carbon filtration polish the final stream; membrane stages are added where reuse or tighter discharge norms demand it. Sludge dewatering and disposal are designed in from the start, not an afterthought.
Start with an effluent characterisation — we'll tell you what treatment train your stream actually needs.
