Full Description

This slide presentation addresses the problem of the simultaneous presence of microorganisms anddisinfectant residuals in distribution systems. Specificgoals include:assess the impact of dynamic water qualityconditions in distribution systems on microorganism inactivation (microorganisms in suspension);benefits of specific disinfectant levels;disinfectant residual as an indicator of microbialintegrity;minimum disinfectant residual to maintain microbialwater quality;concentration of microorganisms that induce ameasurable decrease in disinfectant residualThe 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 microorganismsat the bench scale (2 challenges);evaluate impact of acute and chronic water quality changes ondisinfection efficacy (bench scale, annular reactors); and,evaluate impact of water quality changes ondisinfection efficacy at the pilot scale (pipe loops), andanalytical limitations of secondary disinfectant.
