  • Patent number: 11018345
    Abstract: A method and/or electrochemical cell for utilising one or more gas diffusion electrodes (GDEs) in an electrochemical cell, the one or more gas diffusion electrodes have a wetting pressure and/or a bubble point exceeding 0.2 bar. The one or more gas diffusion electrodes can be subjected to a pressure differential between a liquid side and a gas side. A pressure on the liquid side of the GDE over the gas side does not exceed the wetting pressure of the GDE during operation (in cases where a liquid electrolyte side has higher pressure), and/or a pressure on the gas side of the GDE over the liquid side, does not exceeds the bubble point of the GDE (in cases where the gas side has the higher pressure).

  • Patent number: 10297834
    Abstract: A method and/or electrochemical cell for utilizing one or more gas diffusion 5 electrodes (GDEs) in an electrochemical cell, the one or more gas diffusion electrodes have a wetting pressure and/or a bubble point exceeding 0.2 bar. The one or more gas diffusion electrodes can be subjected to a pressure differential between a liquid side and a gas side. A pressure on the liquid side of the GDE over the gas side does not exceed the wetting pressure of the GDE during 10 operation (in cases where a liquid electrolyte side has higher pressure), and/or a pressure on the gas side of the GDE over the liquid side, does not exceeds the bubble point of the GDE (in cases where the gas side has the higher pressure).

  • Patent number: 10026967
    Abstract: Disclosed are gas permeable 3D electrodes, preferably that have practical utility in, particularly, electro-energy and electro-synthetic applications. Gas permeable materials, such as non-conductive porous polymer membranes, are attached to one or more porous conductive materials. In another aspect there is provided a method for the fabrication of gas permeable 3D electrodes, for example gas diffusion electrodes (GDEs). The 3D electrodes can be utilized in electrochemical cells or devices.

  • Publication number: 20120255903
    Abstract: Disclosed is a method for biological treatment of wastewater in a non-woven membrane bioreactor (MBR) system. The mixed liquor contained in the bioreactor is filtered with a non-woven fabric membrane having a pore size in the range of 0.1 ?m to 5.0 ?m. Membrane fouling is controlled and flux is improved in the non-woven MBR system by adding an effective amount of a water soluble sludge filterability improvement chemical to the mixed liquor.

  • Patent number: 7727434
    Abstract: Membranes as well as a methods of treating membranes are disclosed. The method of treating a membrane includes contacting the membrane with a first solvent, contacting the membrane with an inert solvent, and contacting the membrane with an amine reactive compound. The first solvent includes a solvent having a Hansen solubility parameter in a range from about 10.0 to about 18. The membrane includes a polymer having an amine group.
