Abstract:
A mediated electrochemical oxidation process is used to treat, oxidize and destroy food waste materials, such as manure, biological residue, hay, straw, animal byproducts, bones, horns, blood, biological items, pathological waste and combined waste. Food waste is introduced into an apparatus for contacting the waste with an electrolyte containing the oxidized form of one or more reversible redox couples, at least one of which is produced by anodic oxidation in an electrochemical cell. The oxidized species of the redox couples oxidize the organic waste molecules and are themselves converted to their reduced form, whereupon they are reoxidized by either of the aforementioned mechanisms and the redox cycle continues until all oxidizable waste species, including intermediate reaction products, have undergone the desired degree of oxidation. The process takes place at temperatures between zero degrees centigrade and below the boiling point of the electrolyte.

An electrodialysis cell (40) suitable for removal of paint solubilizer from electrocoat paint ultrafilter permeate includes a tubular, non-conductive housing (42), a substantially cylindrical, hollow object electrode (48) in the housing, a substantially cylindrical counter electrode (52) situated within the hollow object electrode, and a tubular ion exchange membrane (50) around the counter electrode but spaced from the counter electrode as well as the object electrode. The counter electrode and the tubular membrane together define an annular electrolyte passageway while the object electrode and the tubular membrane together define an annular ultrafilter permeate passageway. The object electrode-to-counter electrode area ratio is at least about 6.
Abstract:
A manufacturing method and apparatus of strongly alkaline ionized water exceeding pH 12.0 by electrolysis of water. As an electrolysis solution supplied to a cathode cell of an electrolytic bath, alkaline ionized water produced in the cathode cell is used, and an operation, in which the alkaline ionized water produced in the cathode cell is circulated and supplied to the cathode cell and is subjected to application of electrolytic voltage, is repeated, so that a cation is accumulated to increase the pH value. As a method for circulating and supplying the alkaline ionized water produced in the cathode cell to the cathode cell, a circulation container bath is used, and the circulation container bath and the cathode cell of the electrolytic bath are connected via a circulating line containing a circulating pump. The circulation container bath has a withdrawing system containing a water collecting device for withdrawing alkaline ionized water having a desired pH value to the outside.
Abstract:
An apparatus for electrolyzing fluids. The resulting electrolyzed fluids are particularly suited for treating physiological materials such as whole blood, plasma, or cell isolates in order to reduce the effect of harmful microorganisms. A container holds the fluid and a power supply provides a source of electrical current to an anode and a cathode positioned within the container. The system is particularly suited for disinfecting and/or sterilizing health care instruments. The instruments are bathed in the electrolyzed saline solution. If the instrument includes internal conduits the system of the present invention also preferably flows the electrolyzed saline solution through such conduits also to provide both cleaning and sterilization. The electrolyzed saline solution is recirculated from the electrodes to the instrument being sterilized. Embodiments of the invention are particularly suited to sterilizing dental drill handpieces without damage to the handpieces.
Abstract:
The invention is a method and apparatus using high cerium concentration in the anolyte of an electrochemical cell to oxidize organic materials. The method and apparatus further use an ultrasonic mixer to enhance the oxidation rate of the organic material in the electrochemical cell. A reaction vessel provides an advantage of independent reaction temperature control and electrochemical cell temperature control. A separate or independent reaction vessel may be used without an ultrasonic mixer to oxidize gaseous phase organic materials.
Abstract:
The specification describes an electrolytic cell for the treatment, particularly the purification and sterilization of water, which comprises a closed container with a lower inlet opening and an upper outlet opening for the water and electrodes which are adapted to be connected with the positive pole and the negative pole of a DC source. In the interior of the electrolytic cell free movable particles are located whose density is higher than that of the water to be treated and which are prevented from leaving the electrolytic cell by suitable means adajcent to the inlet and the outlet.
Abstract:
An electrodialytic cell in which electrochemical corrosion of a ferrous anode electrode is inhibited by including said electrode as a wall portion of an anode electrode chamber, of which another spaced wall portion constitutes a permselective membrane, and by sweeping the anode electrode chamber with a water solution containing a hydroxide of a cation selected from the group consisting of sodium, potassium, lithium, cesium, rubidium and ammonium.

A chemical reactor unit is provided that includes first and second circulation loops and an anode arranged between the first and second circulation loops. A first cathode is located at a beginning of the first circulation loop and a second cathode is located at an end of the second circulation loop. The chemical reactor unit can be used to generate a chlorine dioxide solution. A method for generating a chlorine dioxide solution includes applying a voltage differential between first and second cathodes and an anode arranged therebetween and pumping a fluid mixture comprising sodium chlorite and oxalic acid to sequentially pass the first cathode, the anode, and the second cathode. An apparatus is additional provided that includes a tank configured to hold a fluid mixture, a chemical reactor unit, and a pump configured to circulate the fluid mixture between the tank and the chemical reactor unit.
Abstract:
The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.
