Bench-Scale Testing and Cost Comparisons of UV Disinfection Enhanced by Ozone
Abstract:The objective of this study was to evaluate the use of ozone to enhance ultraviolet (UV) irradiation for providing a high-level disinfection of reclaimed water generated at Tampa's 96-mgd Howard F. Curren Advanced Wastewater Treatment Plant (HFCAWTP), while meeting the limits for chlorinated disinfection byproducts (DBPs) in Florida at an alternative discharge location. To achieve this objective, the following activities were performed: (1) bench-scale testing using HFCAWTP filtered effluent for an ozone plus UV disinfection approach and for the approach of using UV disinfection alone, (2) development of the bases of design for both approaches based on the bench-scale testing results and long term on-site monitoring data, and (3) the comparison of cost for both approaches.
