What is Dissolved air flotation or DAF? – Toro Equipment

Dissolved air flotation is based on a physico-chemical process which separates solid and liquid particles by the addition of very small air bubbles These bubbles stick on solid particles and give them a high rate of ascent Once in the surface the solids -the sludge- are pulled mechanically to the hopper Get price
