The flotation process was developed on a commercial scale early in the 20th century to

Dissolved Air Flotation - an overview | ScienceDirect Topics

The flotation process is suitable for stop/start operation and has a flow turndown of about 2:1 or greater depending on the design of aeration manifolds. The former is one of its advantages when dealing with a water subject to high algal loadings; a plant can be ‘switched in’ as and when needed and will give a steady quality treated water within 45 minutes ( Rees, 1979 ).

Dissolved Air Flotation Process in Wastewater Treatment

Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water – then releases it at atmospheric pressure.
