these units are widely in use today. The designs of these plants were typical of early DAF plants, with surface loading rate below 5-7 m/h and flocculation times as high as 45 min. An in filter DAF process was developed in late 1960s, wherein flotation occurs directly above the filter. This process is known as dissolved air flotation/filtration
