Description:
The pilot plant treatability studies were designed to interact with combined sewer overflow (CSO) monitoring and system modeling efforts for the Rochester Pure Water District with the ultimate objective of evaluating CSO abatement alternatives. The studies covered treatment by the following unit processes: flocculation/sedimentation, swirl degritting and swirl primary separation, microscreening with sonic cleaning, dual-media filtration, activated carbon adsorption, sludge dewatering and high-rate disinfection. Pilot operations covered 19 overflow events during the period of September 1975 through June 1976. The studies evaluated the effects of design loadings and influent quality on system performance. Data were evaluated through application models. These models were used to develop optimum cost/benefit comparisons of systems.
