The development of dissolved air flotation (DAF) for drinking water treatment has come a long way. After its pioneering application to water treatment in the 1920s, it was seemingly forgotten until renewed interest in the 1960s in Sweden, Finland, southern Africa and the United Kingdom brought it to attention once more.
The dissolved air flotation process was demonstrated to be a suitable method for efficient tertiary treatment of wastewater, as well as for the elimination of peak pollution loads or by‐pass wastewaters during the treatment plant overloading situations. ABSTRACT Tertiary treatment of municipal wastewater by dissolved air flotation was studied on a pilot‐scale. …
