Dissolved air flotation (also known as DAF) clarifies wastewater by removal of remaining fat, oil and grease (also known as FOG) from effluent which has already passed several primary treatment phases.
Wastewater is pumped into a flotation tank or basin and hit with dissolved air causing microscopic bubbles adhere to suspended solids causing them lift to the surface of the water where it may then be removed by a skimming device and drained toward a sludge discharge tank. Not-floating solids sink to the bottom of the DAF tank from where they are discharged by an automatically controlled pneumatic drain valve.
The goal of dissolved air flotation is to create a system which successfully treats a wide range of suspended solids at a high rate of solids removal. Technology of dissolved air flotation includes a range of components like flotation tank (flotator), skimmer, feed distribution well, and back pressure pump, valve, and saturation (the bubbles generation) system.
For dissolved air flotation, FlotLife supplies full set of technological equipment along with system installation, training and support services.
