This slide presentation addresses the problem of the simultaneous presence of microorganisms and
disinfectant residuals in distribution systems. Specific
goals include:
assess the impact of dynamic water quality
conditions in distribution systems on microorganism inactivation (microorganisms in suspension);
benefits of specific disinfectant levels;
disinfectant residual as an indicator of microbial
integrity;
minimum disinfectant residual to maintain microbial
water quality;
concentration of microorganisms that induce a
measurable decrease in disinfectant residual
The research approach consists of four phases:
revisit existing information including
literature review,
modeling effort,
utility survey, and,
historical water quality data analysis;
determine inactivation potential of microorganisms
at the bench scale (2 challenges);
evaluate impact of acute and chronic water quality changes on
disinfection efficacy (bench scale, annular reactors); and,
evaluate impact of water quality changes on
disinfection efficacy at the pilot scale (pipe loops), and
analytical limitations of secondary disinfectant.
