Abstract:
1. A dissolved gas floatation mixer comprising: a housing having a wall; a movable member disposed in said housing and having a surface spaced from the wall of the housing; an array of irregularities on the surface of the movable member configured to generate cavitation in a fluid within the housing when the movable member is moved at a predetermined rate; at least a portion of said housing being electrically isolated and at least a portion of said movable member being electrically isolated; a motor for moving said movable member in said housing; a source of DC power electrically coupled to said portion of said housing and said portion of said movable member to establish an electrical potential difference therebetween; the positive pole of the source of DC power being electrically coupled to one of said portion of said housing and said portion of said movable member to form an anode thereof; the negative pole of the source of DC power being electrically coupled to the other one of said portion of said housing and said portion of said movable member to form a cathode thereof; at least the surface of the anode comprising a material that is resistant to oxidation to promote the formation of oxygen bubbles on the surface of the anode as a result of electrolysis when a fluid is present within the housing and DC power is supplied by the source of DC power to the anode and the cathode; and an inlet conduit and an outlet conduit coupled to said housing for delivering fluid to said housing and extracting fluid from said housing.
