Wastewater Treatment
Devices

Compared to installing pressure floatation device, our solution requires less cost in terms of facility remodeling as well as reducing the amount of sludge produced

Stable treatment is realized through efficiently biodegrading oils and fats

If untreated inflow water contains a high proportion of oils and fats and is causing the settling properties of activated sludge to deteriorate due to the growth of filamentous bacteria and sludge bulking, which results in unstable treatment…

The application of SKBiO, and using bio carriers for the process before the activated sludge process can improve the biological treatment ability.

Addition in 2011

It can function to immobilize oil and fat degrading bacteria.

In the activated sludge process, there were some concerns about maintaining stable sludge conditions to due to the high amount of oil and fat contained in the drainage.

The combination of SKBiO and ACUACUBE enabled immobilization of oil-degrading microorganisms and consequently realized stable treatment of oil and fat.
