  • Patent number: 8460520
    Abstract: Contaminants are removed from raw water or discharge water from plants, such as sewerage and industrial plants, by applying direct current through an array of spaced, alternately charged electrodes to eliminate or minimize clogging of the electrodes with precipitated contaminants. Polarity may be switched periodically to assist in eliminating or minimizing clogging. In illustrated embodiments, electrode arrays are contained in housings of dielectric material to form modules, To increase processing capacity, the modules are arranged in parallel arrays. Alternatively, a single module is scaled up for large or industrial applications or scaled down for personal use. Instead of housing the electrode arrays in modules through which liquid passes, the electrode arrays for some batch applications are dipped in the water or aqueous solutions.

  • Publication number: 20130032490
    Abstract: A process of electrolyzing water at high temperatures implemented by a cell stack reactor, including: a) simultaneously circulating water vapour at each cathode and at each anode as a leaching gas, temperatures of the water vapour at an inlet of each anode and each cathode being lower than high temperatures at which electrolysis is carried out and the water vapour circulating at the anode being at an overpressure with respect to the cathode; b) upon starting the electrolysis, supplying electrical power having a substantially constant electrical voltage across terminals of the stack and maintaining same. In event of breakage of one or more cells, complete destruction of the stack is avoided and high production efficiency is maintained, and efficiency is maintained during ageing.

  • Patent number: 8303798
    Abstract: The invention is a unit that produces Hydrogen Gas (Browns Gas (HHO)) that can be used as an assist to diesel and gas engines. The gas is produced from distilled water, using our stainless steel plate design. The patent should apply to the internal plate placement and design. The internal design of the unit allows it to produce significantly more hydrogen, drawing significantly less current or electricity from its power source. The internal design is in the placement of positive, negative and neutral plates to produce the gas.
