Abstract:
An apparatus is provided, which includes a mobile body configured to travel over a surface, a source of a liquid, a liquid dispenser and a flow path from the liquid source to the liquid dispenser. A functional generator is coupled in the flow path, which comprises an anode chamber and a cathode chamber separated by an ion exchange membrane and which electrochemically activates the liquid from the liquid source which is passed through the functional generator.
Abstract:
A device includes a first electrode and a second electrode spaced from the first electrode to define a volume. An anion exchange membrane and a cation exchange membrane are disposed within the volume. A controller controls a supply of electrical current from an electrical source to the first electrode and to the second electrode. The electrical current supply is controlled to switch from a first mode of operation to a second mode of operation providing electrical current having a reverse polarity during each cycle. The electrical current is supplied at a controlled cycle rate and for a controlled duration. The cycle rate is greater than about 100 hertz and less than about 10 kilohertz.
Abstract:
Methods, apparatus and systems for treating wastewater onboard small marine vessels. A pre-determined volume of wastewater generated onboard the vessel is mixed with a larger volume of seawater. This mixture is disinfected and subjected to further oxidation. The excess oxidants are neutralized and the treated effluent is discharged overboard the vessel.
Abstract:
A hand-held spray apparatus is provided, which includes a tank for holding a supply of liquid to be treated and a functional generator carried by the hand-held spray apparatus. The functional generator receives the liquid from the tank and has an anode chamber and a cathode chamber separated by an ion exchange membrane and electrochemically activates the liquid that is passed through the functional generator. A spray output is coupled to an output of the functional generator and dispenses the electrochemically activated liquid as an output spray.
Abstract:
A method of reducing naphthenic acids in a wastewater stream. The method begins by processing the wastewater stream to produce a treated wastewater stream with an electrocoagulation device to induce flocculation of the naphthenic acids. The reduction of the naphthenic acids in the wastewater stream occurs from separating flocculated naphthenic acids to produce the treated wastewater stream.
Abstract:
An electrolytic method and apparatus for treating liquids using a flow cell with widely spaced electrodes and polarity reversing power designed to prevent electrode fouling and provide for long continuous liquid treatment running times.
Abstract:
The present invention pertains to an effective system and method for reducing or eliminating the formation of scale in desalination systems. The system utilizes at least one pair of electrodes in direct contact with a liquid to induce an oscillating electric field directly in a portion of the liquid or a liquid stream of the desalination system. The electric field is capable of inducing bulk precipitation of ions, minerals, salts, particulates, contaminants or a combination thereof from the liquid stream.
Abstract:
The invention relates to a reactor for the electrochemical treatment of biomass, including at least two flat surface electrodes positioned equidistantly over the entire surface and separated by less than 1 mm, the space between said electrodes being occupied by a electrolytic solution. Preferably, at least one of the electrodes is an anode and at least one of the electrodes is a cathode. The anode is preferably made from a material selected from among vanadium, selenium, gold, silver, nickel, graphite, graphite galvanised with platinum and graphite galvanised with palladium. The invention also relates to the use of said reactor in electrooxidation reactions involving biomass, particularly polysaccharides, in the production of organic compounds, water electrolysis, hydrogen production or the production of electrochemical cells.
Abstract:
An ion elution unit generates metal ions by applying a voltage between electrodes. Terminals are formed integrally to the electrodes. An interval between the electrodes becomes narrower from an upstream side to a downstream side with respect to a water current flowing through an inside of a casing of the ion elution unit. Terminals that are so laid as to run from the electrodes out of a casing of the ion elution unit are disposed on an upstream side with respect to a water current flowing through an inside of the casing.
Abstract:
An oxidizer generating apparatus having a housing with a fluid inlet at a first end, the inlet leading to a chamber, and a lid attachable to a second end of the housing for closing the chamber. First and second pairs of electrodes are attached to the lid so as to suspend them within the chamber in position to generate chlorine and/or other oxidants from fluid pumped through the housing.
