Active Sludge Reduction

This unique technology uses ozone to penetrate the cell wall of bacteria in part of the return sludge to release the lyses out into the water and then consumed by other bacteria in aeration basin. This process increases the self-degradation speed and mortality of bacteria in aerobic process thus to reduce the amount of activated sludge 30~60% and greatly improve the settling performance in second clarifier.
