Abstract:
The present invention provides an ozone generation and delivery system that lends itself to small scale applications and requires very low maintenance. The system includes an anode reservoir and a cathode phase separator each having a hydrophobic membrane to allow phase separation of produced gases from water. The system may be configured to operate passively with no moving parts or in a self-pressurizing manner with the inclusion of a pressure controlling device or valve in the gas outlet of the anode reservoir. The hydrogen gas, ozone gas and water containing ozone may be delivered under pressure.
Abstract:
An ozone generator which operates at constant pressures to produce a continuous flow of ozone in an oxygen stream having from 10% to 18% by weight of ozone. The ozone generator includes one or more electrolytic cells comprising an anode/anode flowfield, a cathode/cathode flowfield, and a proton exchange medium for maintaining the separation of ozone and oxygen from hydrogen. The ozone generator also has an anode reservoir which vents oxygen and ozone and a cathode reservoir which vents hydrogen. The anode reservoir can be filled from the cathode reservoir while continuing to produce ozone. The ozone generator is readily configured for self-control using a system controller programmed to operate the anode reservoir at a constant pressure.
Abstract:
The present invention is directed to a new water treatment device comprising an electrolytic tank to put water in, an electrode provided in the electrolytic tank, a water treating path for pouring water in a pool and returning to the pool the water in the electrolytic tank, a residual chlorine sensor for measuring the residual chlorine concentration of water, and control means for controlling the energization of the electrode on the basis of the measured value by the residual chlorine sensor, and capable of simply and efficiently sterilizing water stored in pools of various sizes from a swimming pool to a home bathtub.
Abstract:
An apparatus for increasing the quantity of dissolved oxygen in water. The apparatus includes an inlet for receiving untreated water. A cell housing having an electrolytic cell therein is coupled to the inlet. A resident time housing is connected to the cell housing for receiving water having oxygen and hydrogen gas therein. The resident time housing is vertically oriented and longitudinally tending for a selected vertical length above the cell housing. This provides sufficient resident time of the water in a quiet zone to permit the generated oxygen gas to transition into the dissolved state prior to reaching the top of the resident time housing. An outlet is provided at the top of the resident time housing. Treated water having a high dissolved oxygen content is delivered out of the outlet. A gas vent is provided at the outlet to permit the escape of hydrogen or other gases which have not been dissolved into the water. Preferably, a chill unit is provided prior to the electrolytic cell to reduce the temperature of the water to make it pleasing for human consumption and also to increase the quantity of dissolved oxygen which can enter the water. Additionally, a light or other artistic display may be provided adjacent to or with the resident time housing for the pleasure of viewers.
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 present invention is directed to a water purification and dispensing apparatus which receives power through induction to eliminate the presence of exposed electrical contacts terminals. The water dispenser includes a motor driven pump, a water storage area, a rechargeable battery and a nozzle, such that water is pumped from the water storage area out through the nozzle. Two electrodes are provided in either the water storage area or a separate tank for purifying water placed therein. When the dispenser and/or purifying tank is mounted on a base, inductors in the base, the dispenser, and the tank connect via mutual inductance such that power supplied by the base is received by the dispenser and tank. Since power transfers magnetically, there are no exposed contact points which could corrode and/or short if water is accidentally spilled thereon.
Abstract:
The method for producing electrolyzed water includes the step of applying a voltage to electrodes disposed in an electrolytic cell containing therein pure water including electrolyte therein. A strength of an electric field generated by applying a voltage to the electrodes is controlled to be variable by means of various techniques. The method makes it possible to produce electrolyzed water with a smaller amount of energy than prior methods.
Abstract:
In the water electrolyzer, an electrolyzing section has electrodes for electrolyzing raw water. The water pressure sensor detects pressure of raw water introduced into the electrolyzing section. A driver circuit adjusts electric power supplied to the electrodes. A microprocessor controls the driver circuit to adjust electric power supplied to the electrodes on the basis of water pressure detected by the water pressure sensor so as to maintain the pH value of the electrolyzed water in a prescribed range. With this structure, the pH value of the electrolyzed water can be maintained in the prescribed range without reference to quantity of water in the electrolyzing section.
Abstract:
This invention provides electrochemical methods for producing hydroxyl free radicals and decomposing by oxidation chemical substances dissolved in water. It utilizes a novel electrode which is capable of operation at sufficiently positive anodic potential to produce hydroxyl radicals. A complete device for oxidizing chemical substances dissolved in water is described, and operating conditions favorable to the method are discussed. Examples of oxidation reactions are presented, including oxidation of an herbicide, an insecticide, toluene, cresol, and a fluoroalkyl surfactant.
