World Water Works Inc. introduces Ideal S-Select®, a new sludge conditioning technology. The new technology solves the issue of floating or bulking sludge in conventional activated sludge (CAS) wastewater treatment systems.The patent-pending technology is a biological selection process that classifies for denser, faster-settling, bacteria (Phosphate Accumulating Organisms — PAO) to return to the CAS process while wasting the undesirable, hard-to-settle bacteria. The system is applicable to any activated sludge plant, municipal or industrial, with poor or inconsistent performing clarifiers.
