Dissolved air flotation (DAF) is a primary pre-treatment step for wastewater including drinking water and was used as early as the 1920s [81]. DAF removes constituents from water such as: impurities already present (TSS); coagulants/flocculants that were added prior; organic matter; turbidity; algae; Giardia and Cryptosporidium [81] .
DAF Wastewater Treatment System. Dissolved air flotation [DAF] is a treatment process which removes suspended solids, oil and grease from wastewater. Many applications use the DAF process but it is particularly useful for industrial wastewater treatment as it can reduce COD by up to 90%. Dissolved air flotation involves the creation of tiny air ...
Since 2003, a full-scale dissolved air flotation (DAF) process has been operated by the Korea Water Resources Corporation (K-Water) in the Songjeon drinking water treatment plant (SWTP).
