Abstract:
Process and apparatus to remove colloids and nitrogen compounds from contaminated water by coagulating the colloids and separating them from the water. The solids are floated by sparging and then the floating solids are swept from the surface of the water into an exit port using a conveyor from which downwardly depending flaps skim or near the surface, thus sweeping the floating floc into the exit port.
Abstract:
A procedure and apparatus for the concentration of hydrophilic materials through flotation which consists of two devices operating in series. The first device performs the function of feeding the gas and the pulp, generate bubbles and produce contact with the hydrophobic particles to be concentrated. The second device performs the functions of separating and evacuating the froth carrying the hydrophobic materials and the evacuation of the aqueous pulp with the materials with water affinity. The gas-pulp mixing device contains inside it solid mixing means, preferably bead shaped and of a density lower than that of the pulp to be processed. The generation of bubbles and their contact with hydrophobic materials happen when the gas and the pulp transit through the interstices between the mixing media which have discrete freedom to move in the interior. The separation of the froth takes place in a tank without motorized agitation systems volume of which can permit the pulp's residence times within a range of 20 to 60 seconds. This tank has in its upper section overflow ridges and froth collecting troughs. The discharge of the tailings is effected through one or more outgoing pipes placed in the inferior section of the slanted bottom and flow of which is controlled by valves. The selectivity of the concentration is controlled by changing the depth at which the bubbler discharges into the froth separator tank.

Abstract:
The invention relates to a cavitation and electrocoagulation reactor comprising a hollow cylindrical cathode having a cylindrical anode coaxially disposed therein to form an annular interelectrode gap between the contact surfaces. An inlet sleeve and an outlet sleeve disposed in the respective inlet and outlet of the cathode and abutting against opposite ends of the anode seal the interelectrode gap from the respective inlet and outlet of the cathode. A set of channels disposed in the wall of the inlet sleeve connect the inlet to the interelectrode gap. Similarly, a set of openings disposed in the outlet sleeve connect the interelectrode gap to the cathode outlet. An electrical source has first and second terminals respectively connected to the anode and the cathode. The method for removing contaminants from a contaminated fluid flow involves the simultaneous application of hydrodynamic cavitation and electrocoagulation to the contaminated fluid flow.
Abstract:
A hand-held spray device is provided, which includes a tank for holding a supply of liquid to be treated and a functional generator, which is in fluid communication with the tank. The functional generator includes an anode chamber having an anode, a cathode chamber having a cathode and being separated from the anode chamber by an ion exchange membrane, wherein at least one of the anode or cathode comprises a metallic mesh, an inlet coupled to receive liquid supplied from the tank, which is coupled to the anode chamber and the cathode chamber. The functional generator is configured to combine an entire flow of anolyte liquid from the anode chamber with an entire flow of catholyte liquid from the cathode chamber along a single path that passes through an outlet. A pump pumps the liquid from the tank and out the spray output.

Abstract:
A beverage sterilisation device comprises a housing defining an inner space, and having a first and a second end. An electrically insulated fluid path-defining conduit extends through the inner space from the first end to the second end. A first electrode has a first part positioned adjacent to the fluid path and a second part extending perpendicular to the first part. A first counter electrode defines together with the first electrode a first capacitor, and a second electrode having a third part and a fourth part. The third part is positioned adjacent to the fluid path, and the fourth part extends substantially perpendicular to the third part. A second counter electrode defines together with the second electrode a second capacitor. The first counter electrode and the second counter electrode are short-circuited by an electrical connection, and a conductive device is electrically connected between the first electrode and the second electrode. A first trigger point is defined at the second part and remote from the first part, and a second trigger point is defined at the first counter electrode opposite to the first trigger point. The device further comprises an electrical activation circuit for short-circuiting the pair of trigger points and for causing an electric field to propagate from the first trigger point and along the fluid path.
