DAF & MEDIA

KaiDAF

The KaiGO DAF is high efficiency two phase separation machine which removes the suspended solids, grease, oil and the non- soluble organics. This is combined process of flocculation and floatation. Wastewater then enters the flotation zone and microbubbles from the white water attach to the particle surface and affect the particle density, causing the suspended solids to float to the surface of the DAF where they are skimmed by a chain and flight and separated into the sludge hopper. The treated wastewater is continuously removed at several points inside the DAF and is discharged through pipe weirs into an effluent chamber.

KaiMBBR

MBBR is used in the Aeration tank to reduce the biological sludge present in the water. Bacteria grows on the surface of MBBR media that eats the biological matter present in the water. To increase the growth of bacteria in the tank we need to maintain the desired level of dissolved oxygen. Dissolved oxygen level is maintained by providing aeration through diffusers. Selection of MBBR media is very important as it has an impact on civil structure, operating cost and sometimes on capital cost as well.

Conventional and KaiMBBR

Conventional KaiMBBR
Shape Flower shaped Disc, Cube, Webbed shaped
MOC PP/PE PVA, HDPE, PU
Life It’s life is less since it breaks under hydraulic pressure It’s life is more as it can withstand hydraulic pressure because of its unique construction
Surface area Usually from 400-500 m2/m3 Up to 100 times more than conventional
Tank size It requires big tank as it needs more media to grow bacteria and reduce biological matter Smaller tank as the media has more surface area to grow bacteria
HRT 10-12 hrs Reduces compared to conventional
Diffuser type Coarse Bubble Fine/Coarse Bubble

PVA, BioCoin and PU foam

PVA BioCoin PU foam
Surface Area 46,000 m2/m3 5500 m2/m3 3000 m2/m3
MOC PVA HDPE PU
Filling ratio 10% 10% 30%
MLSS Up to 10,000 Up to 10,000 Up to 10,000
