    Dissolved Air Flotation and Membranes

    In the 1960s to 1980s Dissolved Air Flotation (DAF) designs for Water treatment plants were based on 5 to 10 M /hour. This is why DAF became so popular. In the 1990s the design rate became 10 to 15 M / hour In the last 10 years there are some new designs called High Rate DAF where the design loading rate is 20 to 30 M / hour.

    WATER CLARIFICATION BY FLOTATION 1

    variation of temperature, and dissolved air flotation techniques are all based on the release of air from solution by pressure reduction. Air dissolved in the water under atmospheric pressure can be liberated by reducing the surface pressure; this is known as vacuum flotation. Alternatively, air dissolved

    Review Article DAF dissolved air flotation: Potential ...

    versely, in mineral flotation or dispersed air flotation systems, about 10 m3 of air are dispersed into 1 m3 of water (pulp) or 500 times more than that used in DAF. Thus, DAF microbubbles are used to capture only the small, light solids and metal ion hydroxide flocs, bacteria, etc., having specific weights close to that of water.
