摘要： Applicant's faradic porosity cell combines adsorption (physical and capacitive) and faradic immobilization of a target species by optimizing electrode porosity, applied E, and Pourbaix operating regions. The optimization parameters are (i) physical adsorption; (ii) capacitive adsorption; (iii) electrochemical pH modulation; (iv) electrochemical peroxide (H2O2) generation; (v) electrodeposition (e.g., electroplating, electrophoretic deposition); (vi) electrochemical oxidation or reduction; (vii) precipitation; (viii) pore mouth diameter profile, and (ix) electrode spacing, and (xi) flow-by vs. flow-through vs. carbon block cell design.

摘要： An electrochemical device for reducing a dissolved metal of a liquid stream includes a carbonaceous cathode surrounding a metal-containing anode and a separator arranged between the metal-containing anode and the carbonaceous cathode. The electrochemical device further includes either one of: a conductive cathode current collector housing on the carbonaceous cathode or a non-conductive cathode current collector housing on the carbonaceous cathode. The conductive cathode current collector housing includes at least one inlet and outlet for the liquid stream. The non-conductive cathode current collector housing includes at least one inlet and outlet for the liquid stream, and a metal shim arranged between the carbonaceous cathode and the non-conductive cathode current collector housing.

摘要： A modular filtration device is composed of a modular docking plate having at least one quick disconnect plumbing coupling; at least one electrical connector; and at least one alignment feature for aligning and receiving a modular filter; and a modular filter composed of a docking face having: at least one quick disconnect plumbing coupling; at least one electrical connector; and at least one alignment feature that mates with an alignment feature of the modular docking plate to provide proper alignment of the filter with the docking plate, engagement of the quick disconnect plumbing couplings, engagement of the electrical connectors, and engagement of the locking mechanism. The modular filtration device comprises a locking mechanism to hold the filter in place during operation. A modular filtration system is composed of a plurality of the filtration devices.

摘要： The present invention is directed to an electrochemical device for at least partially removing or reducing a target ionic species from an aqueous solution using faradic immobilization, the electrochemical device including at least one first electrode and at least one second electrode with different void fraction and surface area properties, due to differences in void fraction (also referred to as void ratio) of the at least one first and the at least one second electrode, water flows through an electrode with a high porosity, while the aqueous solution does not flow through an electrode with a low porosity. The asymmetry of the electrodes provides a desired voltage distribution across the device, which equates to a different voltage at each electrode, to control the speciation of the target ionic species at the anode and the cathode.

摘要： A method for removing a metal from a carbonaceous electrode includes providing a regeneration solution that includes an acid, an oxidizing agent, or a combination thereof. The method further includes applying the regeneration solution to the carbonaceous electrode, and oxidizing the metal on the surface of the carbonaceous electrode. The method also includes collecting the oxidized metal in the regeneration solution.
