By the continuous addition of the IPT bacterial suspension to a wastewater stream, one is able to repopulate the collection system with bacteria that are incapable of producing external H2S or converting H2S to H2SO4, are more flexible in their oxygen requirements, and are better adapted to the wastewater environment than SRBs are introduced at every flush to the wastewater treatment systems and thrive under anaerobic untreated environments or thiobacilli that thrive in aerobic low pH environments in the presence of dissolved H2S. IPT treatment decreases odor in a wastewater collection system by preventing the proliferation of the organisms causing the odors and decreases corrosion by greatly reducing an essential part of the metabolism of thiobacilli. A continuous addition of the IPT suspension allows gradual repopulation of the biofilm that lines the collection system by non sulfate- reducing bacteria and prevents the proliferation of H2S oxidizing bacteria.
