                                            Process description

Effluent from various sections shall be drained under gravity to a screen chamber for

removal of floating materials . Effluent is further taken to underground basin called

equalization tank equipped with oil free air stripping/ purging system. A twin lobe

blower is provided with air diffusion system for equalization for effluent in the

equalization tank.

The air induced effluent is pumped to the two stage isolated reactor where in dosing of selective flocculants is imparted. The flocculated effluent is let into primary tube settler for separation of flocks. The primary tube settler is provided with special type of media, which helps in faster settling of flocks. Standard rate of settling in conventional clarifiers with scrapper mechanism is 18m3/m2/day whereas rate of setting with special media is m3/m2/hr. The supernatant from the primary tube settler is taken to MBBR reactor tank. MBBR reactor tank is provided with silicon rubber Tubular diffusers for diffused aeration & MBBR media for extended surface aeration

The water with activated sludge from MBBRreactor tank is taken to secondary tube

Settler for separation of activated sludge from the treated effluent. The activated sludge from the secondary tube settler is partially recycled back to the MBBR tank

and rest of the sludge is taken to the sludge drying beds. The clarified water from the secondary tube settler is collected in a sump & further passed through pressure sand filter & activated carbon filter for separation of refractory elements & suspended impurities.

Treated water then pump to UF to enhance more water quality.

Ultra filtration (UF) is a pressure – driven barrier to suspended solids , bacteria ,viruses,

endotoxins, and other pathogens to produce water with very high purity and low silt density.

Ultra filtration (UF) is a variety of membrane filtration, in which hydrostatic pressure forces

a liquid against a semi permeable membrane.

UF treated water then pump to R O plant to achieve water quality for reuse in origin  source. R O is also a pressure driven  barrier  to dissolve solids and salt after RO treatment

is very high purity with less TDS and hardness. RO is a variety of membrane filtration in which reverse osmosis forces a liquid against a semi permeable membrane

AND Sludge from tube settlers is withdrawn on sludge drying beds. Sludge on drying

disposed off by way of land filing. The treated effluent is with aforesaid characteristics may be partially reused for dyeing after mixing a part of fresh water.
