This paper discusses the first phases of an AwwaRF project on evaluation anddevelopment of high-rate SFBW treatment processes. The project objective is to provide utilitieswith the information required to implement high-rate SFBW treatment devices to achieve anoverall lower cost and footprint requirement. The research initiated in October 2005 evaluatesexisting data, complemented by collection and evaluation of new data from bench-, pilot-, andfull-scale studies. The existing data includes data published in the literature and unpublished datafrom drinking water utilities and equipment manufacturers. This research focuses on publishedand unpublished data, plus new data generated during this research, for high-rate SFBWtreatment processes. Several manufacturers provided pilot and full-scale data on high-rateprocesses that have been evaluated. The proposed project also includes an evaluation of existinginnovative full-scale processes through on-site testing and performance evaluation.The pilot phase of the project will take place at two cities that represent very differentSFBW qualities -- Cleveland, Ohio and Central Utah Water Conservancy District (CUWCD). TheSFBW quality of these two cities is representative of the range of conditions identified inprevious research (e.g., Cornwell et al. 2001). The pilot equipment to be tested has beenselected, to target only those processes for which sufficient data does not already exist.The final report will be geared to the development of the Implementation Section thatwill include a discussion of process performance, SFBW quality applicability, design parameters,operations issues, need for site specific pilots, and cost. The report will also include twoexample preliminary design reports. The hardcopy report will be complemented by a web-baseddecision support tool that AwwaRF subscribers can use to interactively review and evaluatetreatment options targeted for their particular site-specific conditions. Includes reference, table.
