  • Patent number: 10087091
    Abstract: In a submerged discharge device, a pair of electrodes is arranged in a liquid in a reservoir to receive an alternating voltage from an alternating power source, thereby generating a submerged discharge using a discharger arranged in the liquid between the pair of electrodes. A surface of this pair of electrodes has a coating that ensures the submerged discharge generated by the discharger. This may reduce the area of contact between the surface of the pair of electrodes and the liquid in the treatment vessel to reduce the consumption of the pair of electrodes.

    Abstract: There is a method of facilitating the consolidation of fine tailings through the application of an electrical current. The fine tailings include a combination of at least some water and some clay particles. Electrodes are placed into contact with the fine tailings. An AC voltage with a DC offset is applied to the electrodes to separate water from the clay particles and to induce movement of the separated water to a collection area. The separated clay particles can consolidate more readily than unseparated clay particles. In an embodiment, the fine tailings are mixed fine oil sands extraction tailings which include residual hydrocarbons. In an embodiment, the application of an AC voltage with a DC offset across the electrodes includes applying an AC voltage of about 1 V/cm and a DC offset of about ½ V/cm.

    Abstract: A method of improving natural gas release from a well via an enhanced hydraulic fracturing operation. The method includes capturing or retrieving the flow back from the well following the fracturing operation. The flow back or other source water is introduced to an electrocoagulation (“EC”) treatment process. EC treatment separates the water from other fracturing fluid components in the flow back and also removes bacteria and other contaminants. Thereafter, the EC-treated fluid is recycled for subsequent fracturing operations. The process may also be used to treat all source water, including fresh water delivered to the well before it is used as a fracturing fluid.

  • Patent number: 8771499
    Abstract: Axially fed fluid is sheared during long residence time in a radial workspace between counter-rotating coaxial disk-shaped centrifugal impellers. Gases evolve in the fractal turbulence of a shear layer, which is forced between laminar boundary layers, and an axial suction pump axially extracts evolved noncondensables and volatiles through cores of radial vortices in the shear layer. Cavitation due to shear between the impellers kills pathogens by shock waves, microjets, OH radicals, and nearby UV light pulses. Oppositely charged electrodes bounding the workspace cause electroporesis and electrohydraulic cavitation. The electrodes are counter-rotating ridged armatures of disk dynamos, forming a dynamic capacitor having audio frequency pulsed electric fields. Electrode erosion by arcing is prevented by shear between the electrodes.

    Abstract: A deionization apparatus for regenerating electrodes using vibration and a method of controlling the same. The deionization apparatus includes electrodes to which ions contained in a fluid are absorbed, and a piezoelectric element to separate the ions absorbed to the electrodes by vibration. Since the ions absorbed to the electrodes are separated using mechanical energy generated by the piezoelectric element, it may be possible to more rapidly perform regeneration of the electrodes.

  • Patent number: 8691097
    Abstract: The system and method is directed to improved separation or clarification of solids from a solids-laden liquid and removal of entrained gasses. A liquid to be treated is introduced into the inlet of a solid-liquid separator modified to include one or more sources of vibrational energy. The liquid is directed through a conduit within the separator. This conduit can be configured into a tortuous flow path to assist in the separation of solids from the liquid. Vibrational energy is applied to the flow path, preferably through the flow path conduit. As solids fall out of solution, they are collected. The clarified liquid is also collected. A vacuum can be applied to the system to assist in moving the solid-liquid mixture through the system and to provide vacuum clarification. Electrocoagulation electrodes and gas sparging can also be employed along with height adjustable weirs and an oil accumulator.

  • Patent number: 8679515
    Abstract: Contaminants are filtered from a fluid flow stream and the filter is regenerated by a process including steps of: providing a filter material comprising both carbon and potassium iodide; passing a contaminated fluid stream in contact with the filter material; adsorbing contaminants from the fluid stream onto surfaces in the filter material; passing an electric current through the filter material with adsorbed contaminant thereon; disassociating contaminant from the surfaces of the filter material; and removing disassociated contaminant from the filter material by carrying away the disassociated contaminant in a fluid flow mass. Separately, a stable, active iodine solution is also provided for numerous deodorizing and disinfecting applications.

  • Publication number: 20140076804
    Abstract: A method precipitating struvite in wastewater uses a magnesium sacrificial anode as the only source of magnesium. A high-purity magnesium alloy cast anode was found to be very effective in recovery of high-quality struvite from water solutions and from supernatant of fermented waste activated sludge (WAS) from a high-purity oxygen wastewater treatment plant. Struvite purity was strongly dependent on the pH and the electric current density. Optimum pH of the solution was in the broad range between 7.5 and 9.3, with struvite purities exceeding 90%. The precipitated struvite accumulated in bulk liquid with significant portions attached to the anode surface from which regular detachment occurred.

  • Patent number: 8663444
    Abstract: Prolongation of the lifetime for reduced water is attempted. Production water that presents alkalinity is produced by utilizing raw water with ionized metallic minerals being dissolved therein and hydrogen gas H2. When inpouring the hydrogen gas together with the raw water into an electromagnetic portion in the apparatus, the hydrogen gas is bubbled and ionized to produce ions. The gas bubbles of the ionized hydrogen-ions are miniaturized. By making a metallic mineral as a core, hydrides (H?), which are negative ions in the hydrogen ions, coordinate on the periphery of that core. The metallic minerals which are complex-ionized (complex-ionized metallic minerals) based on a fact that the hydrides coordinate are dissolved in the water stably for long period of time, so that production water which presents alkalinity, that is, reduced water can be obtained. The reduced water can be utilized as drinking water. A metal container is preferable for a refilling container.

  • Patent number: 8658014
    Abstract: A method of reducing naphthenic acids in a wastewater stream. The method begins by processing the wastewater stream to produce a treated wastewater stream with an electrocoagulation device to induce flocculation of the naphthenic acids. The reduction of the naphthenic acids in the wastewater stream occurs from separating flocculated naphthenic acids to produce the treated wastewater stream.
