摘要： A method for controlling power supplied to an ozone water generator is disclosed. The ozone water generator includes an electrolytic plate unit. The electrolytic plate unit includes an anode plate assembly composed of a plurality of anode plates, a first cathode plate assembly composed of a plurality of first cathode plates, and a second cathode plate assembly composed of a plurality of second cathode plates. In the process of electrolyzing water, the two cathode plate assemblies alternately obtain a relatively high-level signal at a short time, and the two cathode plate assemblies obtain a relatively low-level signal at other times. During the use of the ozone water generator, the scale formed on the surface of the cathode plate assembly can be removed in time, so as to ensure the electrolysis performance of the ozone water generator, without descaling by chemicals. No maintenance is required.

摘要： An electrochemical cell for wastewater treatment is disclosed comprising a catalyst coated membrane, an open pore mesh placed next to the catalyst coated membrane, on each side of the membrane, and a compression frame placed next to each of the open pore meshes. The open pore meshes and the compression frames are made of a conductive material. Each compression frame has compression arms spread within the area delimited by the perimeter of the frame to apply a uniform compression force across the anode and cathode active areas through fasteners which protrude through the compression arms, the open pore meshes and the catalyst coated membrane. A stack comprising at least one such electrochemical cell is immersed in a reactor tank containing the wastewater to be treated.

摘要： An electrochemical system and method are disclosed for On Site Generation (OSG) of oxidants, such as free available chlorine, mixed oxidants and persulfate. Operation at high current density, using at least a diamond anode, provides for higher current efficiency, extended lifetime operation, and improved cost efficiency. High current density operation, in either a single pass or recycle mode, provides for rapid generation of oxidants, with high current efficiency, which potentially allows for more compact systems. Beneficially, operation in reverse polarity for a short cleaning cycle manages scaling, provides for improved efficiency and electrode lifetime and allows for use of impure feedstocks without requiring water softeners. Systems have application for generation of chlorine or other oxidants, including mixed oxidants providing high disinfection rate per unit of oxidant, e.g. for water treatment to remove microorganisms or for degradation of organics in industrial waste water.
