Abstract:
A self-powered self-contained electrolysis device, for placement into a reservoir of a contaminated electrolytic solution, such as water, containing halide ion, such as chloride ion, to electrolyze the water, thereby disinfecting or sterilizing the contaminated reservoir of water. Contaminated reservoirs of water can be water containers filled with river water and other outdoor sources, or can be contaminated municipal water held in kitchen containers, cooling systems, water tanks, cisterns, etc. The self-contained body allows the electrolysis device to float on or remain self-contained in the reservoir water. Preferred devices are small and portable, and comprise reliably productive electrolysis cells that are powered by batteries. A means for propulsion of the device can also be provided, and is preferably a pump that pumps the water through the electrolysis cell.
Abstract:
An improved chlorination system for pools, spas, potable water supplies, and the like, provides a vertically oriented electrolytic cell connected between a pump and a lightly salinated pool. The cell preferably contains a metallic electrode, such as copper, and a precious metal coated titanium electrode, and has means for passing an electric current through the cell. The present invention further provides a novel electrode stack design, conducive for forming an efficient chlorinator comprising a plurality of interconnecting electrode stacks of separate electrical cells.
Abstract:
Dielectric rails (112) support an electrode stack (109) that is compressed between end pressure plates (118). The stack is composed of a dielectric spacer (46, 103) forming a central spacer opening, separating a pair of electrode plates (101,102) that each have a different configuration of openings. A first electrode plate (101) of the pair has a central aperture, while the second electrode plate (102) of the pair has peripheral apertures. A compression device such as a hydraulic cylinder (124) compresses the stack, sliding the plates and spacers together to form a pressure-tight reaction chamber (108). When the cylinder is released, any plate or spacer is readily removed from the stack for replacement or maintenance merely by lifting it off the rails. An electric potential can be applied to each electrode plate at a connecting ear (116), which may be a one of the rail guides (116).

Abstract:
A method and apparatus for contaminant separation utilizes an interleaved array of oppositely charged electrode plates for fluid treatment. Spacing between the parallel electrode plates is graduated so that the volume of the cavities between the opposing electrodes provides varying levels of treatment of a broad range of contaminants from a variety of fluid columns. A fluid flow path extending substantially orthogonal to the direction of the electrical field established between opposing electrode plates provides a feed stream with exposure to the varying levels of electrical charges between the electrode plates. The method and apparatus provides an effective means of contaminant separation by a device having a small footprint and requiring low amounts of electrical energy.
Abstract:
Purified water is obtained from tap water. NaCl is added to the purified water so that the conductivity thereof is at least 100 &mgr;S/cm. Then, electrolysis is applied. The obtained cathode water is output and neutralized. The obtained cathode water includes dissolved hydrogen (H+, H., H2) of at least 0.1 ppm. This dissolved hydrogen prevents or suppresses DNA damage.
Abstract:
An alkaline electrolyte solution is electrolyzed by a diaphragm-less electrolyzer to provide electrolytic water as purging and disinfecting water. The alkaline electrolyte solution is a mixture of at least one alkaline electrolyte selected from caustic sodium carbonate, caustic potassium carbonate, phosphorous sodium carbonate and sodium hypochlorite, and at least one neutral salt selected from sodium chloride, potassium chloride, sodium bromide and potassium bromide. The purging and disinfecting water is added to a water circulatory system. The result is that contaminants and noxious chemicals in the circulatory system are oxidation decomposed to thereby purge the circulating water, and noxious microorganisms such as germs, yeasts, fungi, and viruses, growing in the water circulatory system and causing degradation of water or development of slime are disinfected and thereby purged from the water circulatory system. The purging and infecting method can be carried out in a simple manner with minimum cost.
Abstract:
Deionizers using the electrode configurations of electrochemical capacitors are described, wherein the deionizing process is called capacitive deionization (CDI). During deionization, a DC electric field is applied to the cells and ions are adsorbed on the electrodes with a potential being developed across the electrodes. As electrosorption reaches a maximum or the cell voltage is built up to the applied voltage, the CDI electrodes are regenerated quickly and quantitatively by energy discharge to storage devices such as supercapacitors. In conjunction with a carousel or Ferris wheel design, the CDI electrodes can simultaneously and continuously undergo deionization and regeneration. By the responsive regeneration, the CDI electrodes can perform direct purification on solutions with salt content higher than seawater. More importantly, electrodes are restored, energy is recovered and contaminants are retained at regeneration, while regeneration requires no chemicals and produces no pollution.
