  • Patent number: 11548798
    Abstract: A foam electrode comprising surface treatment by the steps of: 1) impregnating soft compressible polymeric foams with a conductive coating via sequential infiltration synthesis and 2) functionalizing the chemically altered voids with an ultrathin redox coating to enhance capacitive deionization (CDI). The redox coating will allow treated foam to absorb ions under the application of a bias, and mechanical compression/decompression. The CDI apparatus uses the void volume of the foam in the uncompressed state to flow liquids through it while the compressed state is used to enhance desalination by limiting the diffusion pathways for the ions to find an adsorption surface.

  • Patent number: 11530143
    Abstract: This disclosure provides techniques for treatment of aqueous matrices using electrolysis to produce soluble metals. An aqueous matrix of interest is passed through an electrolysis device with at least one consumable electrode, which dissolves under applied current, transferring a desired reagent to the aqueous matrix of interest. In one embodiment, the electrolysis device is used in a water delivery network to passivate hexavalent chromium (Cr6) and/or convert it to trivalent chromium; the electrode can be made of food-grade metal tin, which is electrolyzed to form a stannous reagent, which then reacts with the Cr6. The disclosed techniques provide for Cr6 passivation without requiring the use of concentrated acids or other harmful substances. Long term reagent generation efficiency can be enhanced through the use of cleaning processes which maintain a fresh electrode surface in contact with the aqueous matrix of interest.

  • Patent number: 10843147
    Abstract: A method and apparatus are provided for mixing highly viscous fluids to form a mixture. The mixture is created rapidly and has a high level of uniformity. The mixture is created by utilizing induced viscous fluid folding under the influence of an electric field. The electric field is introduced by connecting a nozzle dispensing the fluids in parallel to a voltage supply and grounding a collection plate located below the nozzle. When a certain voltage is applied the co-flow viscous fluids start to fold because the electric field exerts stress on the surface of the fluids, which results in changes of the geometry and dynamics of the viscous fluids. Control of the electric field provides great control over the mixture.

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: 20140262788
    Abstract: A method and apparatus for conditioning water is disclosed. Water is flowed past a probe, wherein the water may include impurities. The probe is energized to excite the water and a presence of electrons in the excited water is reduced to produce positively charged water downstream of the probe that causes the impurities to dissociate from the water. The excited water may be deposited on a soil for crop production. The excited water may be further deposited on the soil to flush impurities in the soil to a depth away from a root of a crop planted in the soil to reclaim the soil for crop production. The excited water may further be used to descale pipes, such as used in irrigation, heat exchangers, cooling systems, etc. In yet another embodiment, the probe may be energized at a frequency selected to destroy organism, thereby protecting ecosystems.

  • Patent number: 8808433
    Abstract: A novel method and system of separating carbon dioxide from flue gas is introduced. Instead of relying on large temperature or pressure changes to remove carbon dioxide from a solvent used to absorb it from flue gas, the ion pump method, as disclosed herein, dramatically increases the concentration of dissolved carbonate ion in solution. This increases the overlying vapor pressure of carbon dioxide gas, permitting carbon dioxide to be removed from the downstream side of the ion pump as a pure gas. The ion pumping may be obtained from reverse osmosis, electrodialysis, thermal desalination methods, or an ion pump system having an oscillating flow in synchronization with an induced electric field.

    Abstract: The present invention is directed to a novel method for cleaning a filter surface using a plasma discharge self-cleaning filtration system. The method involves utilizing plasma discharges to induce short electric pulses of nanoseconds duration at high voltages. These electrical pulses generate strong Shockwaves that disintegrate and dislodge particulate matter located on the surface of the filter.

The devices and systems can include an electrode configured to generate an electric field gradient in proximity to an intersection formed by the divergence of two microfluidic channels from an inlet channel. Under an applied bias and in the presence of a pressure driven flow of saltwater, the electric field gradient can preferentially direct ions in saltwater into one of the diverging microfluidic channels, while desalted water flows into second diverging channel. Also provided are methods of using the devices and systems described herein to decrease the salinity of water.

  • Patent number: 8740600
    Abstract: An apparatus for charging particles in non-conductive liquids, so they agglomerate and can be removed by filtering, is comprised of a housing which contains a non-conductive insert having a multiplicity of channels. The incoming stream is divided into two halves, each of which is flowed through a set of charging channels which contain electrodes, preferably metal brush-like electrodes. One set of electrodes is charged to a high positive voltage; the other set is charged to a high negative voltage. The liquid streams are then merged and flowed trough a set of mixing channels, along the path of which are one or more reversals in flow direction. The mixing channel path length is substantially longer than the charging channel path length.
