dissolved air flotation daf has been successful in treating industrial wastewaters. in many cases, such as in poultry effluent treatment, daf proves to be an effective pre-
a process for treating waste water from a food processing plant consisting essentially of introducing an effective amount up to 150 ppm of a source of hydrogen peroxide into the waste water discharge from a food processing plant which contains fat, oil or grease, or mixtures thereof, contacting said waste water with said hydrogen peroxide to create a flotation effect through hydrogen peroxide decomposition to fine oxygen bubbles and water and removing said fat, oil or grease or mixtures
flotation cell can be relatively thin or thick. the level of the floatation cell can be either increased or decreased by raising or lowering the effluent weir to allow for the most efficient skimming of either thin or thick sludge blankets. just remember not to set too high so as to create an overflow condition in the daf unit scum chamber. and
manual grease relubrication is probably the single most out-of-control aspect of machinery lubrication, but it doesnt have to be that way. the right amount can be calculated easily with a few measurements and quick formulas or charts from bearing suppliers.
pre-treatment of trade wastewater by a system based on the dissolved air flotation daf principle is a commonly used best practice option, where grease arrestors or other simple passive pre-treatment devices are inadequate. at its heart, micro fine bubbles of air generated in the daf vessel combine with insoluble

flotation cells that have been developed utilizing hydraulic principles only. hydraulic induced gas flotation igf in the oil industry must remove very fine oil droplets 10-50 microns from hypersaline water using methane as the bubble gas.
five minutes conditioning time and 15 minutes flotation time are desired. adding 15% as a volume factor for aeration, the estimated flotation cell volume needed will be 290 cubic meters. if cells of 29,000 liters volume are chosen, n will be 10. similarly calculating for the 5-minute conditioning time at the same pulp density gives see below .
principle of operation. this slurry more properly called the pulp of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles. the hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth.
