Design and Sizing of a Dissolved Air Flotation Separator

Design and Sizing of a Dissolved Air Flotation Separator

Flow Rate In general, DAF separators are sized by the flow rate verses the separation chamber's effective surface area or projected surface area in the case of a DAF with enhanced coalescing or parallel plate media. Therefore, the effectiveness of any DAF separator is affected by the flow rate. The slower the flow, the better the results.
