Patent ID: 7033495

Claim:
A self-contained dissolved air flotation system for purifying influent water, said system comprising: a flocculation tank; a flotation tank having an upstream end and a downstream end; an influent water supply port in fluid communication with the flocculation tank and a flocculation tank output communicating downstream to the upstream end of the flotation tank; a skimmer disposed above the flotation tank, said skimmer extending transversely across the flotation tank; means for driving the skimmer from the upstream end of the flotation tank to the downstream end of the flotation tank, thereby pushing float out of the downstream end the flotation tank; a float collection tank disposed downstream of the flotation tank, in position to receive float from the downstream end of the flotation tank; an output manifold disposed in the lower portion of the downstream end of the flotation tank for drawing clean water from the flotation tank; a standard shipping container, wherein the flocculation tank, flotation tank, and float collection tank are positioned in-line along the length of the shipping container; and a control system operable to operate the skimmer to translate along the length of the flotation tank and correspondingly operate a conveyor belt to convey float deposited thereon into the float collection tank at predetermined intervals.
