  • Patent number: 10227243
    Abstract: The present invention provides a system for prevention of adhesion of organisms in water to a substrate in contact with the water, wherein the substrate and the water flowing around the substrate form together a treated region, comprising a generator for producing electromagnetic wave having a time varying frequency, in electrical connection with a first excitation site of the treated region and with an avalanche current suppressor having its another terminal connected with a second excitation site of the treated region. A selected voltage is applied to the generator such that the generator is triggered to produce the electromagnetic wave capable of inducing an avalanche current to shock or kill the organisms. The invention also provides a method for prevention of adhesion of organisms in water to a substrate in contact with the water.

  • Patent number: 9951437
    Abstract: Among other things, one or more systems and techniques for promoting metal plating uniformity are provided. An insulator plate is positioned relative to a semiconductor wafer that is to be electroplated with metal during a metal plating process. The insulator plate comprises an insulator ring that provides a resistance to electrical plating current passing through the insulator ring to the semiconductor wafer. The insulator plate comprises one or more porous regions, such as holes, that introduce little to no additional resistance to electrical plating current passing through such porous regions to the semiconductor wafer. The insulator plate influences electrical plating current so that edge plating current has a current value similar to a center plating current. The similarity in plating current promotes metal plating uniformity for the semiconductor wafer.

    Abstract: An apparatus and method for removing contaminant species from water by electrocoagulation are described. Alternating grounded, rotating, planar circular electrodes and stationary planar electrodes function as a Tesla fluid pump when placed in contact with the contaminated water, causing the water to flow between the rotating and stationary electrodes. An insoluble abrasive material introduced into the water removes scale from the electrodes while the water is pumped thereby. A direct electric current is caused to flow between each pair of rotating and stationary electrodes, thereby producing electrocoagulation of the contaminants in the water flowing therebetween. The electrocoagulated materials may be separated from the treated water by filtration or by permitting the treated water to stand for a chosen period.

  • Publication number: 20130134046
    Abstract: A device and method is provided for increasing production of hydrogen during electrolysis. Initially, one of the vibrational modes of an electrolytic fluid is determined. A laser is then tuned to a wavelength near the selected vibrational mode. The tuned laser is then applied to the electrolytic fluid during electrolysis. The application of the laser with a wavelength near the wavelength of a specific vibrational mode of the electrolytic fluid causes an increase in the rate of production of hydrogen, when compared to electrolysis alone. The specific vibrational mode may correspond to a mode that stretches the inter-atomic bonds of hydrogen in the electrolytic fluid.

  • Publication number: 20130118994
    Abstract: Systems and methods have been developed for treating waste water and produced water, so as to remove contaminants therefrom. The systems and methods allow specifically for the removal of contaminants from produced water from oil and gas wells, fracturing flow-back water, and water- or brine-based drilling fluids. The water is treated by contacting the contaminated fluid with ozone after contacting the fluid with a diffused air system to generate small bubbles for entrainment of some contaminants. Thereafter, the water is contacted with an electro-coagulation system in order to remove flocculants and adjust the pH and the total dissolved solids levels of the fluid.

  • Publication number: 20130032486
    Abstract: An apparatus and method for smelting has a smelting pot for containing electrolyte, alumina and a layer of liquid aluminum. A wall in the form of one or more TiB2 or alumina plates extends from the bottom of the pot to a height exceeding the height of the liquid aluminum layer formed in the bottom of the smelting pot during smelting. The wall partitions the bottom of the pot and impedes movement of the aluminum under the influence of MHD forces, diminishing the maximum crest height of waves in the aluminum and allowing a reduction in the ACD to reduce electrical resistance and power consumption. The wall may equal or exceed the height of the anode and may, when conductive, act as a cathode, drawing a horizontal current. The wall may be composed of alumina, e.g., in the form of blocks, undergoing electrolytic reduction and being replaced periodically.

  • Publication number: 20120121491
    Abstract: A system for forming metal hydroxide from a metal carbonate utilizes a water electrolysis cell having an acid-producing anode and a hydroxyl-producing cathode immersed in a water solution of sufficient ionic content to allow an electric current to pass between the hydroxyl-producing cathode and the acid-producing anode. A metal carbonate is placed in close proximity to the acid-producing anode. A direct current electrical voltage is provided across the acid-producing anode and the hydroxyl-producing cathode sufficient to generate acid at the acid-producing anode and hydroxyl ions at the hydroxyl-producing cathode. The acid dissolves at least part of the metal carbonate into metal and carbonate ions allowing the metal ions to travel toward the hydroxyl-producing cathode and to combine with the hydroxyl ions to form the metal hydroxide. The carbonate ions travel toward the acid-producing anode and form carbonic acid and/or water and carbon dioxide.
