OZONE IN WASTEWATER: THE CITY OF PHOENIX EXPERIENCE
Abstract:The City of Phoenix is investigating various disinfection technologies for its 91st Avenue wastewater treatment facility: (1) ultraviolet light (UV), (2) ozone, (3) UV/hydrogen peroxide, (4) ozone/hydrogen peroxide, (5) and UV/ozone. In addition to providing disinfection, the City would like to consider the removal of EDC's and PPCP's in the treatment technology evaluation. In order to identify the most economical disinfection system, the evaluation included bench-scale testing of the technologies considered and a year-long water quality monitoring study. This paper presents the results of the bench-scale analyses and estimated capital and O&M costs.
