This paper reports on the first phase of an investigation conducted by Antwerp Water Works (AWW) in Belgium to make a long term (12 months) comparison between SBF and high-rate dissolved air flotation (DAF) to determine which process would be optimal. The investigation included construction of a pilot plant consisting of an Actiflo unit (40 m3/hr or 50 - 80 m/hr) and Aquadaf unit (20 m3/hr or 25 - 35 m/hr) with downstream filtration units. The results of this study show that there are important differences with the units effect on water quality and performance of downstream processes. Furthermore it clearly points to the value of this type of demonstration testing can bring to water companies. Includes figures.
