Dissolved Air Flotation systems effectively remove TSS, FOG, and other pollutants from wastewater. Conceptually, the DAF process is simple – tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water – but designing a DAF system for a real-world application isn’t quite as simple.

Deinking - Wikipedia

Froth flotation was adapted from the flotation process used in the mining industry in the 1960s. It is the most common deinking process in Europe used to recover recycled paper.Often most of the collector is added to the inlet of the flotation. The process temperatures are normally in the range 45 - 55 °C.
