Dissolved Air Flotation: Laboratory, Pilot Plant, and Field Investigations

Investigates dissolved air flotation (DAF) as an alternative to gravity settling. In the first phase, relates air requirements to source water quality and pretreatment conditions, and compares DAF performance with conventional treatment on a lab and pilot scale. In the second phase, evaluates performance of DAF facilities in North America and Europe, and develops cost data for this process relative to conventional treatment. Results of first phase published in 1992 as Dissolved Air Flotation: Laboratory and Pilot Plant Investigations. Results of second phase published in 1994 as Dissolved Air Flotation: Field Investigations.
