Dissolved Air Flotation Systems
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 realworld appliion isn''t quite as simple.

The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5. The exact range at any given plant is optimized for the ore at that site. Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite. Particle Size

There are various different types of sedimentation: granular particles will each settle separately and will each be subject to a constant settling speed particles that are more or less flocculated will be of different sizes and, therefore, subject to variable sedimentation rates. At low concentration levels, the settling speed increases as the floc increases in size through collision with
