Flocculation and Air Requirements for Dissolved Air Flotation

Edzwald, James K. / Walsh, John P. / Kaminski, Gary S. / Dunn, Howard J.

Bench‐scale and pilot‐plant studies were used to investigate the effects of flocculation time and floe size on the performance of dissolved air flotation and to determine air requirements for three different types of water supplies. The results show that long flocculation periods are not needed and suggest that floe particles of 10–30 μm should be prepared for flotation. Two measures of the air supplied were examined: percentage recycle and the bubble volume concentration or the volume of air released per volume of water treated. Bubble volume concentrations of 4,600 ppm or 8 percent recycle were sufficient to effectively treat all the waters tested.
