Description:
This research summary presents the results of a pilot-scale disinfection study performed for the New York City Department of Environmental Protection and the U.S. Environmental Protection Agency (US EPA) under a contract to Camp Dresser & McKee of Woodbury, New York. The main objective of the pilot study was to demonstrate alternatives to hypochlorite disinfection for application to the Spring creek facility and potentially to other combined sewer overflow (CSO) facilities. The pilot testing was divided into two phases. Phase I evaluated treatment performance of five technologies: ultraviolet (UV) irradiation; ozonation (O3); chlorine dioxide (C1O2) disinfection; chlorination/dechlorination (C12)/deC12); and electron beam, irradiation (E-Beam). The fifth technology, E-Beam was evaluated during supplemental Phase I pilot testing sponsored by the New York Power Authority and the Electric Power Research Institute. Based on the results from Phase I, Phase II provided additional evaluation of technologies that had shown potential for CSO applications. These were UV, C1O2), and (C12)/deC12). This Research Summary concentrates on these three technologies, but the overall results of both phases for each technology along with the cost are also discussed.
