NON-STRIPPING BIOREACTOR FOR BIOLOGICAL SULFIDE OXIDATION FROM WASTEWATERS

A method is presented for biological removal of contaminants like sulfide from ground waters and industrial waters. A portion of the bioreactor effluent water is recycled to the bioreactor and the sulfide oxidizing bacteria by biological oxidation oxidizes sulfides in the water to produce soluble su...

Summary:A method is presented for biological removal of contaminants like sulfide from ground waters and industrial waters. A portion of the bioreactor effluent water is recycled to the bioreactor and the sulfide oxidizing bacteria by biological oxidation oxidizes sulfides in the water to produce soluble sulfates. The present invention uses a packed bed bioreactor configuration that uses packing material to maximize the concentration of sulfide oxidizing bacteria.
