ABSTRACT:
Apparatus for treating potable water to remove odorous sulfur compounds therefrom is disclosed. The apparatus comprises a treating tank, a fogging nozzle, means for directing water to be treated through the fogging nozzle and into the treating tank, means for injecting compressed air into the water directed through the fogging nozzle, a filter vessel, and a de-aerating vessel. The compressed air injected into the water that is directed through the fogging nozzle is at a pressure sufficiently high that minus 100 micron water droplets leave the fogging nozzle. Air, most of the sulfur compounds present in the water and some entrained water are ultimately discharged from the treating tank. The means for directing the water to be treated through the fogging nozzle is controlled to maintain a predetermined water level in the treating tank. The filter vessel contains a bed of a filter medium which forms a loose bond with the remaining H.sub.2 S in the filter vessel. The apparatus also includes means for directing water from the treating tank through the filter bed and into the de-aerating vessel, means for injecting air into water withdrawn from the treating tank before it flows through the filter bed, and means for venting gases from the de-aerating tank.
