  • Patent number: 5531865
    Abstract: A method for removing contaminants from a flow of wastewater using an electrolytic oxidation vessel having a chamber and at least one elongate cathode electrode and a plurality of elongate sacrificial anode electrodes aligned parallel with the cathode electrode in the chamber. The flow of wastewater is directed through the chamber of the electrolytic oxidation vessel in a direction parallel with the cathode and anode electrodes so that the flow of wastewater engages the cathode and anode electrodes. A voltage is applied across the cathode electrode and the sacrificial anode electrodes to create a current having a density ranging from approximately 5-7 ma/sq. cm so as to release ions from the anode electrodes which oxidize and render insoluble contaminants in the flow of wastewater and create insoluble contaminants and substantially cleansed water. The insoluble contaminants are separated from the substantially cleansed water. An apparatus for use with the method is provided.

  • Patent number: 4849115
    Abstract: An apparatus for oxidizing organic residues in an aqueous stream, comprising a chamber having a top, a bottom, an inlet for introducing a liquid thereinto, and an outlet for removing liquid therefrom, a plurality of dividers in the chamber between the inlet and the outlet dividing the chamber into a plurality of subchambers, a plurality of ultraviolet lamps in the subchambers, means for directing liquid flow through the chamber in a serpentine fashion, a plurality of separate subcovers over the subchambers and the lamps, which subcovers may be individually opened and closed, conductors for supplying electrical current to the lamps, and means for interrupting the flow of current to the lamps under each subcover when the subcover is open while simultaneously permitting such current flow to lamps which are not under an open subcover.

  • Patent number: 4496443
    Abstract: A method for infusing substances into liquids through the use of electrolysis allows mixtures having controlled concentrations at predetermined proportions to be produced. The liquids with infused substances may be used as feedstuff for plants and/or animals; e.g., water mixed with magnesium compounds may be used to enrich the diets of plankton and/or cattle. The electrolysis apparatus allows the infusion to occur continuously into a flowing stream of liquid, allows the rate of infusion to be controlled, to a predetermined concentration regardless of the flow rate of the stream and affords means of self-cleaning to the electrodes to maintain the electrolytic reactions at high coulometric efficiency.
