The polishing stage that makes reuse limits consistently achievable
Secondary treatment alone will not hold BOD, TSS and turbidity within CPCB reuse limits under varying load. The tertiary stage is what converts a compliant-on-paper plant into a consistently compliant one, and it is included as standard on every plant we supply.
Click any vessel to read what it does.
Pressure, media, membrane, and storage stages are separated so the operating sequence and optional UF bypass are easy to understand.
Graded silica sand captures fine suspended solids and reduces turbidity.
Follow the numbered train from inlet to treated-water reuse. Click any stage for its engineering note.
From clarifier or settling tank.
Reduces TSS to below 10 mg/l, meeting the CPCB reuse requirement.
Adsorbs residual colour, odour, dissolved organics and free chlorine.
Delivers odour-free, visually clear water for domestic flushing.
Optional UF removes suspended solids, colloidal matter, bacteria and cysts almost completely.
Backwash water is returned to the collection or equalization tank — no net effluent loss.
Included as standard on every plant we supply for reuse duty.
