    Abstract: The polarized electrode flow through capacitor comprises at least one each electrode material, with a pore volume that includes meso and micropores, with contained anionic or cationic groups. The polarized electrodes are in opposite polarity facing pairs, separated by a flow path or flow spacer. Both polarities of the particular attached ionic groups used are ionized at the working pH or composition of the particular feed solution supplied to inlet of the flow through capacitor. The contained groups cause the electrodes to be polarized so that they are selective to anions or cations. The polarized electrode flow through capacitor has better performance compared to identical flow through capacitors made from non-derivitized carbon. The capacitor electrode materials so derivitized provide this polarization function directly without need for a separate charge barrier material.

    Abstract: A point of use irrigation water fertigation system utilizes plasma production of nitrogen-bearing species. Soluble nitrogen-bearing species are generated using an atmospheric air plasma treatment of an irrigation water supply. A plasma is generated by a tube having an air intake. A high frequency generator generates atmospheric plasma. The end of the tube is placed above the surface of the irrigation water supply and the plasma emanating from the tube generates nitrogen species in the water. The non-thermal plasma discharge efficiently produces highly reactive radicals and NOx species that have impact on water chemistry including inactivation of microorganisms with high efficacy and accelerated removal of persistent organic pollutants such as perfluorinated compounds (PFCs) from water samples. Plasma ignition can be initiated with a low flow of helium gas injection. Upon ignition, the gas is transitioned to a helium/room air mix, immediately followed by a transition to ambient room air only.

  • Publication number: 20140008229
    Abstract: There is a method described of treating tailings which are composed of at least some water and clay particles. Within the tailings, at least some water molecules are weakly bond to the clay particles to form a gel like fluid from which water does not readily separate. An alternating current is applied to the tailings to change the electro-chemical properties of the tailings to reduce the weak bonding between the water and the clay particles so that water within the treated tailings is able to separate. Water within the treated tailings is then allowed to separate without further application of electricity. In some embodiments, the treated tailings are allowed to separate through evaporation. Liquid tailings may also be treated with alternating current by applying alternating current to the liquid tailings at a voltage gradient range of 1 to 5 V/cm for a total duration of 24 to 300 hours. The application of alternating current may further comprise applying alternating current at a frequency of 1 to 30 Hz.

  • Patent number: 8616239
    Abstract: There is disclosed apparatus and processes for increasing fluidity of a flowing fluid. The apparatus may have a number of treatment chambers adapted to receive and pass the flowing fluid. In each treatment chamber a field is applied to the fluid. The fields may be parallel to the fluid's direction of flow, and may alternate in sequence. The fluidity of the fluid is increased through exposure to the fields.

  • Patent number: 8580098
    Abstract: Electrostatic filters, systems and methods having separate positively and negatively charged filter elements within electrically isolated filter tanks for electrostatically filtering particles from a fluid flow. Both positive charged connections biased to earth ground and negative charged connections biased to earth ground are made to the respective positive and negative charged filter elements, along with triboelectric induced charge accumulations from the fluid flow, for separating charged particles within the fluid flowing parallel through these oppositely charged filter elements. Variable resistors of a power supply connected to such filters, systems and methods provide for controlling and adjusting for any undesired voltage excesses and/or shortfalls within these filter tanks so that the fluid flowing exiting these filter tanks is unbiased to generate a filtered fluid having balanced electrostatic charges.

  • Patent number: 8524080
    Abstract: An apparatus for removing cyanotoxins and excess ions from contaminated water. Contaminated water passes from a storage tank (200), through a sand filter (210), through a reaction chamber (230), and finally through a carbon filter (270). The sand filter removes particulates and some bacteria. Treatment of the water in the reaction chamber first destroys cyanotoxins, algae, and bacteria through the use of high voltage shocks applied between two groups of electrodes (285, 285?), then the voltage on the electrodes is lowered and electrolysis is used to sequester free ions in the water in the region near the electrodes. Partially treated water is removed from the upper portion of the reaction chamber and passed through a carbon filter (270) to remove radiation, and to improve taste and smell. After passage through the carbon filter, the water is potable. The water remaining in the reaction chamber is discarded into a reservoir (265).
