This paper discusses the use of dissolved air flotation (DAF) to cost-effectively remove turbidity, algae (and associated taste and odor), color, organics, metals, as well as Cryptosporidium and Giardia. DAF can easily adjust to rapid changes in raw water temperature and water quality while continually producing consistent effluent for filtration and concentrated sludge solids for further processing. The fundamentals of dissolved air flotation are discussed and examples of pilot plant performance are presented. Includes tables, figures.
