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.
