  • Publication number: 20140138247
    Abstract: An apparatus, method, process, and system for the treatment of a water stream are provided. Such apparatus, method, process, and system characterized by applying a voltage to a pair of electrodes to generate an electric field with such electric field applied across a water stream passing there between the pair of electrodes. At least one of the pair of electrodes comprises a metal, and one or more of a plurality of positively charged ions in the water stream are substituted with one or more positively charged ions of the metal. Additionally, one or more of a plurality of negatively charged ions may react with the one or more positively charge ions of the metal to form an ionic compound. One or more of any remaining of the plurality of positively charged ions may reaction with another one or more of the plurality of negatively charged ions.

  • Patent number: 8716982
    Abstract: A bipolar overvoltage battery pulser and method are provided that apply a positive pulse voltage and a negative pulse voltage alternately across the terminals of a battery. The object of the bipolar overvoltage battery pulser and method is to increase the cycle lifetime and capacity of storage batteries, such as lead acid batteries. The rise times for the leading edges of the positive pulses and for the trailing edges of the negative pulses are short compared to the ionic relaxation time in the electrochemical solution. Alternating between the positive and negative pulses gives each new pulse an equal starting condition without realizing any memory effect that otherwise may result if the last applied pulse was of the same polarity, which reduces the extent of overvoltage that may be applied to the battery and decrease the highest useable pulse cycling frequencies that could be achieved without experiencing pulse overlapping.

  • Publication number: 20040056640
    Abstract: A method of reducing the build-up of lead sulphate in an electric lead/acid accumulator (1) through pulsing an electric current through the accumulator, where one or more pulse generator(s) (10) is/are electrically connected to the individual cells (4a, 4b, 4c, 4d, 4e, 4f) of the accumulator (1) by means of leads (12a, 12b, 12c, 12d, 12e, 12f, 12g). Means at pulse generator (10) for connection to an electric lead/acid accumulator, where one or more pulse generator(s) (10) is/are electrically connected to the individual cells (4a, 4b, 4c, 4d, 4e, 4f) of the accumulator (1) via leads (12a, 12b, 12c, 12d, 12e, 12f, 12g).
