A hydrogen-enriched water generator and dispenser includes a main casing, a hydrogen water generator supported in the main casing, and a water tank. The hydrogen water generator includes a magnetic field generator and an electrode arrangement supported in the main casing. The water tank is adapted for storing a predetermined amount of regular water. The magnetic field generator is arranged to deliver electromagnetic wave having ultra-long wavelength to the regular water stored in the water tank upon electrolyzing and ionizing by the electrode arrangement, so that the regular water is electrolyzed and ionized to contain a predetermined amount of hydrogen ions for direct consumption.

An apparatus for dehalogenating an aqueous salt solution may include a tank, an electrode pair positioned at least partially within the tank, and an aerator positioned at least partially below an anode of the electrode pair. An inlet of the tank may be configured to introduce the aqueous salt solution into the tank, and as the aqueous salt solution contacts the electrode pair that may include a voltage potential between the anode and cathode, electrolysis occurs and the halogens in the aqueous salt solution, e.g. chloride, may be oxidized at the anode. The aerator may be configured to sweep the halogens to the top of the tank.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell.

In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

A flexible electrocatalytic membrane for removing nitrate from water, a preparation method and use thereof are provided. The method of the present invention includes dropwise adding an aramid fiber solution into deionized water to prepare an aramid nanofiber sol, then reacting an ethanol solution containing 3,4-ethylenedioxythiophene and ferric nitrate with the aramid nanofiber sol to prepare a conductive aramid nanofiber sol, and finally dropwise adding MXene nanosheets ultrasonically pretreated by a tetramethylammonium hydroxide solution into the conductive aramid nanofiber sol to prepare the flexible electrocatalytic membrane. The prepared flexible electrocatalytic membrane possesses good mechanical strength and flexibility, and can not only effectively remove nitrate but also avoid failure of electrocatalytic materials due to surface fouling in the process of electrocatalytic reduction of nitrate, and thus has a long service life.

A system for an efficient and sustainable electrochemical treatment of wastewater comprises a reactor tank, a first electrolyzer with a stack of electrolytic cells, each electrolytic cell comprising an anode of a first composition, and a second electrolyzer with a stack of electrolytic cells, each electrolytic cell comprising an anode of a second composition, and a contaminant concentration measuring device for monitoring the contaminant concentration in the reactor tank to the first or to the second electrolyzer. Wastewater to be treated is supplied from the reactor tank to the first electrolyzer until the contaminant concentration becomes substantially constant as measured by the contaminant removal rate being around 0 mg/h, which indicates the buildup of byproducts generated in the first electrolyzer, at which time the wastewater is supplied from the reactor tank to the second electrolyzer with anodes which can efficiently treat the byproducts of the reaction in the first electrolyzer.

An electrolyte solution production device includes: an electrolysis unit that includes a stacked body having conductive film stacked and interposed between electrodes adjacent to each other and is configured to electrolyze a liquid; and housing having the electrolysis unit disposed in an inside of the housing. In addition, housing includes inflow port into which the liquid supplied to the electrolysis unit flows and outlet port from which an electrolyte solution produced in the electrolysis unit flows out. Conductive film has protrusion that protrudes toward the inner surface of housing and is provided to position conductive film with respect to housing. This can provide the electrolyte solution production device in which conductive film can be downsized and easily positioned with respect to housing.

A system and a method for separation of ions from ions-containing medium is disclosed herein, that utilizes capacitive-faradaic fuel cells (CFFC) particles coated at least partially with catalysts capable of catalyzing redox reactions provided a reductant (fuel) and/or an oxidant, thereby polarizing the particles to more effectively absorb charged species (ions) from the water upon introducing, e.g., H.sub.2 gas or O.sub.2 gas, in the medium during the adsorption or regeneration. The same concept is utilized in a hybrid electrochemical cell for providing a system and a method for generating and converting electrochemical energy.
