Abstract
A method is presented for biological removal of contaminants like sulfide from ground waters and industrial waters. A fixed film compartmentalized bioreactor or bioreactors are used to convert sulfide to elemental sulfur and the subsequent conversion of the elemental sulfur to sulfates. The present invention uses a packed bed bioreactor configuration that uses packing material to maximize the concentration of sulfide oxidizing bacteria.
