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.

The present invention concerns a method for reducing the amount of polluting and/or valuable elements through application of electrolysis, in particular of the electrocapturing phenomenon. The electrolysis according to the present invention is applied permanently over time in a polluted water body. The predetermined action area (115bis, 115ter) preferably has a smaller extension than the water body. The at least one phenomenon (125bis, 125ter) is preferably powered electrically through production of electrical energy in loco through at least one renewable energy source (140). The method is suitable for purifying large expanses of water, like seas, lakes, lagoons and rivers, through plants operating permanently, however this does not rule out other applications.

The present disclosure discloses a novel membrane-less water electrolysis method for obviously increasing electrolysis efficiency. The method focuses on enabling more impurities in water to be electrolyzed to produce many electrons and conductive ions, and creating good conditions to increase water electrolysis efficiency. A spacing of a gap reserved between a positive electrode and a negative electrode is designed according to a reasonable minimization principle, and the gap is less than 5 mm and more than 0 mm, thereby benefiting enhancement of electrolysis between the impurities and the water molecules in the water; and in a water electrolysis process, the water can smoothly flow in the gap between the positive and the negative electrodes, and a probability and quantities of the impurities and the water molecules electrolyzed by the positive and the negative electrodes are increased, thereby increasing the electrolysis efficiency of the water.

The regeneration unit includes at least one anode and cathode in a first space which generate regeneration water containing hydrogen ions (H+). The softening unit is disposed in a second space partitioned from the first space and includes an ion exchange body regenerated by the regeneration water.

A novel magnesium-based alloy is described. The alloy is particularly suitable for the construction of electrodes, especially anodes, that can be used for an electrochemical process, such as the synthesis of struvite. The magnesium-based alloy is an AZXY alloy in which A is aluminium and Z is zinc, X represents the content, expressed in wt. %, of the first element, and Y the content, expressed in wt. %, of the second element. The AZXY alloy according to the invention has 2%≤X≤4% and 0.5%≤Y≤2%, and an iron (Fe) content of less than 0.005%, and preferably less than 0.003%. The anodes constituted by this novel alloy have a much slower corrosion speed and improved performances compared to existing anodes. An electrode cartridge comprising said alloy and suitable for being inserted into an electrolytic reactor so as to form, once assembled, an electrocoagulation unit, is also described.

A water-disinfecting apparatus includes a vessel with a cathode, an insert with a photoanode, an ultraviolet light source configured to be positioned in the insert, and a power source. The cathode forms an electrically conductive layer on an inner surface of the vessel. The photoanode is configured to be positioned in the cathode. The power source is configured to be operably coupled to the cathode, the photoanode, and the light source.

An efficient, cost-effective, and efficacious technique for removing coal ash and other pollutants from waterways, ponds, marshes, holding tanks and other water sources and supplies. An apparatus comprising an open cage including electromagnets and/or permanent magnets and/or electrodes is supplied with electrical power to extract materials such as rare earth elements and/or heavy metals. The materials levitate to the surface, forming a shiny while leaving water substantially free of such materials.

A three-dimensional electrode-ozone oxidation-electrocatalytic membrane coupled wastewater treatment device, including a circulating fluidized bed reactor. The circulating fluidized bed reactor includes a funnel-shaped internal, a truncated cone, a fiber ball filter, a gas-liquid distribution plate, an inner cylinder, an intermediate cylinder and an outer cylinder. The inner cylinder, the intermediate cylinder and the outer cylinder are coaxial. The inner cylinder is an electrocatalytic membrane assembly; the intermediate cylinder is a gas diffusion electrode; and the outer cylinder is a stainless-steel mesh. A particle electrode is filled between the intermediate cylinder and the outer cylinder, and between the intermediate cylinder and the inner cylinder. The intermediate cylinder is connected to a negative electrode. The inner cylinder and the outer cylinder are connected to a positive electrode. A wastewater treatment method using the device is also provided herein.

Electrocoagulation (EC) reactors having pellet flow circuits are disclosed. In one embodiment, the EC reactor includes a reactor vessel having a first inlet and an outlet through which a contaminated feed stream is received and discharged, respectively. An EC reaction chamber is located within the reactor vessel, fluidly coupled between the first inlet and the outlet, and configured to be loaded with consumable EC pellets. The EC reactor further includes an EC pellet flow circuit around which the consumable EC pellets circulate as the contaminated feed stream flows through the EC reaction chamber. First and second electrodes are coupled to the reactor vessel and positioned to generate an electrical field. The consumable EC pellets are exposed to (e.g., pass through or circulate within) the electrical field to induce coagulation of contaminants within the contaminated feed stream as the feed stream flows through the EC reaction chamber.

The invention relates to the field of electrochemical production of disinfectants, where a solution of alkaline metals is used as the electrolyte in the anode chamber. The invention offers a new design for electrolyzers, reducing power consumption in the production of disinfectants by known methods. As a result of this invention, power consumed in the production of 1 gram of active chlorine by known methods will be reduced by 20%, and the possibilities for producing disinfectants with active chlorine content 7500 ppm in an electrolyzer without channelling the water into external cooling devices will also expand.
