ABSTRACT:
The present invention is a gas scrubbing system for removing hydrogen sulfide gas from a wastewater system. Pumps draw wastewater from a wastewater source within the system for injection through aerators which aerats aspirate hydrogen sulfide gas and oxygen from the wastewater source. The aerators mix the wastewater with the hydrogen sulfide gas and oxygen which is returned to the system as oxygenated wastewater containing elemental sulfur. The water and sulphur are then delivered to the treatment plant for final treatment.
