  • Publication number: 20150065339
    Abstract: Catalysts prepared from abundant, cost effective metals, such as cobalt, nickel, chromium, manganese, iron, and copper, and containing one or more neutrally charged ligands (e.g., monodentate, bidentate, and/or polydentate ligands) and methods of making and using thereof are described herein. Exemplary ligands include, but are not limited to, phosphine ligands, nitrogen-based ligands, sulfur-based ligands, and/or arsenic-based ligands. In some embodiments, the catalyst is a cobalt-based catalyst or a nickel-based catalyst. The catalysts described herein are stable and active at neutral pH and in a wide range of buffers that are both weak and strong proton acceptors. While its activity is slightly lower than state of the art cobalt-based water oxidation catalysts under some conditions, it is capable of sustaining electrolysis at high applied potentials without a significant degradation in catalytic current. This enhanced robustness gives it an advantage in industrial and large-scale water electrolysis schemes.

    Abstract: To remove a contaminant from a liquid, a pulsed electrical arc discharge is effected between two electrodes immersed in the liquid, thereby creating a plurality of particles within the liquid. One or both of the electrodes is metallic, for example iron or titanium. Before the pulsed electrical arc discharge is terminated, another step that promotes destruction of the contaminant by particles, such as removing the particles from the liquid or adding an oxidizer to the liquid, is performed. In the case of the extra step being adding an oxidizer to the liquid, preferably the termination of the pulsed electrical arc discharge is followed by allowing the liquid and the particles therein to age.

    Abstract: The invention relates to the treatment of a medium, particularly to the purification of water, air, or surfaces. A photo-active layer (120) is disposed on an energy-transfer surface (111) of a substrate (110). Thus light energy transfer from said substrate (110) to the photoactive layer (120) is directly achieved without an intermediate passage through the medium. The substrate (110) may preferably be a waveguide from which light energy is transferred into the photoactive layer (120) via evanescent waves. Moreover, the optical coupling between the substrate (110) and the photoactive layer (120) may spatially vary.

The cavitation generating chamber is operable to generate cavitation bubbles. A method of treating a liquid comprises directing a fluid from a supply chamber into a cavitation generating chamber by constricting the fluid through an orifice, wherein the orifice has a cross dimension that is substantially less than a cross dimension of the supply chamber, such that a fluid jet is formed. The method further includes allowing the fluid jet to expand downstream of the orifice such that the velocity of the fluid is reduced so that the jet axial velocity head at the chamber outlet is less than the difference between the static pressure within the discharge chamber and the vapor pressure of the fluid. The method also includes discharging the fluid into a discharge chamber via a chamber outlet.

The invention discloses a cost efficient and environmentally friendly process and apparatus for cleaning and recycling of flowback, or frac water, which has been used to stimulate gas production from shale formations. The apparatus is mobile and containerized and suitable for installation at the well site.

  • Patent number: 8273249
    Abstract: A new method that integrates electrochemical oxidation and flocculation processes for removing ammonia nitrogen in coking wastewater is disclosed in this invention. It comprises steps as follow: first, adjusting the PH of coking wastewater and adding Fe2+ into the wastewater; then leading the wastewater containing Fe2+ through such 5 areas as pulsed high-voltage discharge oxidation area, pulsed high-frequency DC electrolytic oxidation area, microbubble oxidation area, flocculation area and precipitation area in succession. High-voltage pulse and high-frequency pulse are two different mechanisms for achieving strong oxidation. With help of both solid and liquid catalysts, these two oxidations can work synergistically. The recalcitrant organic chemicals are effectively destroyed and satisfactorily removed out of wastewater. The high-concentration coking waster pretreated with this method will meet Chinese highest discharge standard as long as the routine biochemical treatment is applied thereafter.

  • Publication number: 20120138545
    Abstract: Provided herein are systems and methods for the treatment and purification of fluids (e.g., water) using a light-emitting diode (LED) light source. In one embodiment, for example, there is provided a fluid flow conduit having an LED light source and a photo-catalytic material disposed therein. The LED light source emits ultraviolet light with a peak wavelength between about 265 nm and about 400 nm. In operation, the photo-catalytic material absorbs the ultraviolet light from the LED light source, and releases free radicals into the fluid. The free radicals then degrade organic substances (e.g., bacteria) in the fluid.

  • Patent number: 8119008
    Abstract: Disclosed is a method of purifying fluid, typically an aqueous fluid steam, with the method involving at least two reverse osmosis stages with retentate from a first reverse osmosis stage being subjected to the second reverse osmosis stage, and with intermediate treatment of retentate from the first reverse osmosis stage by exposure to an electric field. The intermediate treatment may involve electrocoagulation to remove sparingly-soluble compounds and permit enhanced reverse osmosis recovery. Additional treatment may be performed prior to the first reverse osmosis stage, between the first reverse osmosis stage and the intermediate treatment with an electric field, between such intermediate treatment and the second reverse osmosis stage, or after the second reverse osmosis stage.
