Abstract
A system and method for the ozone treatment of wastewater is disclosed. The disclosed wastewater treatment system includes a high selectivity reactor coupled to an activated sludge treatment basin. The high selectivity reactor is adapted to receive a stream containing sludge diverted directly or indirectly from the activated sludge treatment basin. The disclosed wastewater treatment system and method is adapted to inject a chemical agent, such as ozone-enriched gas, into the diverted stream for treatment within the high selectivity reactor for purposes of sludge reduction, foam control, or bulking control. The treated stream is then returned to the activated sludge treatment basin.
