Dissolved Air Flotation (DAF)

Dissolved Air Flotation (DAF) is a widely used method for separating solids and floatables such as oil and grease out of liquids. DAF is used extensively together with the MBBR technology in industrial applications, typically in two main configurations: Primary DAF before the MBBR, in order to remove solids and reduce the organic load to the biological system; or by applying the DAF process after the MBBR stage, in order to separate bio-solids coming out of the MBBR from the final effluent.

DAF Advantages：

●High efficiency dissolved air system with dissolving efficiency reaches above 95%；

●Liquid level controlling for automatic slagging, slagging scum moisture content below 98%；

●High efficiency non-clogging releaser with particular purpose, easy maintenance, releasing rate above 95%;

●Stable treatment efficiency, automatic control, unattended operation；

●Small footprint, high effluent quality, low investment；
