dissolved air flotation design

Dissolved Air Flotation Separator Design -Flow Diagram The Impact of TSS & FOG Ratios on DAF Design There are many factors that impact the overall design of a dissolved air flotation system, but the most important by far is the combined TSS & FOG (in parts per million) content of the wastewater. For example, look at the following spreadsheets.

    Dissolved Air FlotationSystems

    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.
