Patent ID: 8753508

Claim:
A flotation water treatment system for treating water, comprising: an inlet zone for receiving the water to be treated; a mixing zone for receiving water from the inlet zone; a flotation zone for receiving water from the mixing zone; a clarified water collection area for receiving water clarified in the flotation zone; one or more spray nozzles disposed in the mixing zone for injecting pressurized water into the mixing zone and generating air bubbles in the mixing zone such that the air bubbles are mixed with the water to be treated; a perforated panel separating the inlet zone and mixing zone and including an array of openings through which water to be treated passes as the water to be treated moves from the inlet zone to the mixing zone; wherein the openings in the perforated panel give rise to a homogenous mixture of the water to be treated and the air bubbles that result from the pressurized water being injected into the mixing zone by the one or more spray nozzles; and a network for directing pressurized water to the one or more spray nozzles, and where the network includes a first distribution network for directing pressurized water to the one or more spray nozzles at a first flow rate, and a second distribution network for directing pressurized water to the one or more spray nozzles at a second flow rate.
