Abstract
A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream direction, and deposits the float in a collection tank. Clean water may be drawn from the flotation tank continuously, while float may be removed periodically.
Claims11
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, and a corresponding upstream end wall and downstream end wall;
- 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 conveyor belt disposed downstream of the downstream end of the flotation tank, positioned relative to the flotation tank to receive float pushed from the flotation tank, said conveyor belt being operable to convey float away from the flotation tank, in the downstream direction;
- a float collection tank disposed relative to the conveyor belt to receive float from the conveyor belt;
- output manifolds disposed in the lower portion of the downstream end of the flotation tank for drawing clean water from the flotation tank.
