Abstract:
The present invention intends to provide a water purification apparatus that is small and easy-to-use, yet being capable of efficiently creating flocs of impurities and removing the impurities from the wastewater in a single pass. To achieve this objective, an inner tubular anode 12 made of stainless steel or carbon is inserted into an outer tubular cathode 11 made of aluminum, leaving a predetermined intermediate space 13 between them, and electrolysis is carried out to produce aluminum hydroxide. The aluminum hydroxide thus produced serves as the medium for flocculating the impurities in the wastewater ascending the intermediate space 13. The wastewater containing the flocs of impurities is filtrated with a filter 18 within a filtering and settling tank 17. As a result, the impurities are completely removed from the wastewater.
Abstract:
An apparatus for concentration and deactivation of actinide nuclear materials having a pair of spaced apart electrodes made of a composite material including at least one oxide, at least one carbon-containing material and lead, a nuclear waste water stream flowing between the electrodes, and a DC power supply operably connected with the electrodes. When a voltage is applied to the spaced apart electrodes, nuclear cations in the nuclear waste water stream are attracted to one of the electrodes and anions in the nuclear waste water stream are attracted to the other of the electrodes, forming a substantially deionized water stream and a concentrated nuclear waste stream.
Abstract:
Process and apparatus to remove colloids and nitrogen compounds from contaminated water by coagulating the colloids and separating them from the water. The water is then continuously oxidized with chlorine electrolytically to destroy the nitrogen compounds.
Abstract:
A process to purify wastewater that comprises the steps of passing the wastewater through an electrocoagulation cell which comprises a plurality of reaction plates or electrodes (6) disposed within said cell and spaced apart from each other, whereby said wastewater is treated by passing an electric current through the wastewater to thereby produce purified water (8); re-using said purified water for cleaning or other purposes to produce wastewater; and recycling (3) the wastewater back to the electrocoagulation cell. The wastewater may be obtained public or household showers, sinks, basins, baths, washing machines, dishwashers, kitchens or car washes.
Abstract:
An apparatus for sanitizing water, comprising a pump, a plurality of cells, a conduit system connecting the plurality of the cells with each other and with the pump; and a valve system at the conduit system for directing the flow of water through the conduit system. Each cell comprises an inlet and an outlet for a flow of water, an electrically-conductive tubing housed in the cell and connecting with the inlet with the outlet; and an electromagnetic pulsing device connected to the tubing.
Abstract:
A system and method for dewatering particulate materials employs an improved dewatering probe generally including a single non-conducting pipe having a plurality of holes or slots, an anode mounted on the pipe adjacent one end of the pipe, and a cathode mounted on the pipe adjacent the opposite end of the pipe. The pipe serves as both a sonde for mounting the anode and cathode and as a well for extracting water that collects around the outside of the pipe and flows into the interior of the pipe through the holes or slots via gravitational and electro-osmotic forces. A pump may be used to extract both collected water and accumulated electrolytic gases from the pipe's interior. In embodiments, an array of guide electrodes is mounted on the pipe in addition to the anode and the cathode in order to deflect the major current flow out into the body of surrounding particulate materials. The guide electrodes also facilitate rapid depolarization of the probe. An array of probes according to the present invention may be employed as a system to dewater a volume of particulate.

Abstract:
A water treatment reactor adapted to simultaneously carry out electrocoagulation and advanced oxidation processes is disclosed, which includes an upright sealed tank having a metal body, or a metal mounted on an inner wall thereof, used as a cathode; a sacrificial electrode used as an anode, which is disposed in the tank and non-electrically connected to the cathode; a mixing device disposed in the bottom of the tank for enabling mixing of influent water and an air or oxygen-containing gas introduced into the tank; a gas-liquid separator which is in fluid communication with the tank at the top for expelling a gas from the tank without expelling water; and a direct current supply having a positive electrode electrically connected to the anode and a negative electrode electrically connected to the cathode.
Abstract:
A method and apparatus for the generation and collection of an aqueous peracid solution at the cathode of a PEM electrolyzer. The electrochemical process introduces carboxylic acid (such as distilled table vinegar, lactic acid, citric acid or combinations) to the anode and a source of oxygen to the cathode. The PEM electrolyzer has a gas diffusion cathode having a cathodic electrocatalyst that is capable of hydrogen peroxide generation. The peracid solution is generated at the gas diffusion cathode and the solution is very pure and may be used for disinfecting or sterilizing various items or solutions. In a second embodiment, the carboxylic acid may be provided directly to the cathode, such as in the form of an acid vapor.
Abstract:
A water treating apparatus is provided which is capable of producing a hypochlorous acid-containing electrolytic water having a satisfactory sterilizing ability in a household. The water treating apparatus is an apparatus for producing hypochlorous acid in for-treatment water containing a salt by use of an electrochemical reaction which occurs in the for-treatment water when a direct current voltage is applied to at least a pair of electrodes oppositely disposed in the for-treatment water, wherein the direct current voltage to be applied to the electrodes is obtained by smoothing an alternating voltage of domestic use power supply into direct current power of a predetermined voltage, an electrode having titanium covered with a coating containing at least palladium or ruthenium is used as an anode, and at most 90% of the salt added to the for-treatment water is converted into hypochlorous acid by the electrochemical reaction.
