Impact of wastewater treatment processes on disinfection byproduct formation potential in treated wastewater

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Three continuously-stirred tank reactors and two sequencing batch reactors were designed to simulate different wastewater treatment processes in the laboratory. For the continuously-stirred tank reactors with different solid retention times and resultant levels of nitrification, haloacetic acid formation potentials decreased as retention time increased and nitrification level improved. Trihalomethane formation potentials, however, showed an opposite trend due to the influence of soluble microbial products. For both sequencing batch reactors with complete nitrification, the oxic-anoxic reactor with better denitrification resulted in lower disinfection byproduct formation potentials compared to the anoxic-oxic reactor. By comparing oxic and anoxic phases in a cycle of their operations, oxic phases were found to have faster removal rates and greater removal efficiencies than anoxic phases. Major reductions of disinfection byproduct formation potentials were accompanied with bulk removal of wastewater organics, and contribution of soluble microbial products became significant thereafter. 2011
