Dissolved air flotation (DAF) is a secondary wastewater treatment process that utilizes rising air bubbles to float suspended solids and dispersed liquids. The floating particles are then skimmed off the surface with a rotating chain and flight system. There are two main types of DAF systems, DAF thickeners and DAF separators.
Dissolved air flotation systems are designed to remove fats, oils and grease (FOG), suspended solids (TSS), biological oxygen demand (BOD), food/animal production/processing wastes, industrial wastes, hydrocarbon oils/emulsions and many other contaminants. Clarification rates as high as 97% or more can be achieved using these systems.
