The present invention relates to a hydrogen water and sterile water-generating device that generates hydrogen water and sterile water by electrolysis. The hydrogen water and sterile water-generating device includes an electrolysis part that has at least two electrodes and electrolyzes water, a water introducing channel that introduces water into the electrolysis part, and a switch mechanism that switches the polarity of the electrodes between positive and negative, and hydrogen water and sterile water are generated in the same path by the switch mechanism switching the polarity of the electrodes between positive and negative during electrolysis.

A system for electrohydromodulation of wastewater. In an embodiment, the system comprises an anode in contact with at least one anodic chamber and a cathode in contact with a cathodic chamber. Each anodic chamber and the cathodic chamber are configured to receive a flow of wastewater. A first multivalent cation exchange membrane, between each anodic chamber and the cathodic chamber, allows multivalent cations to pass therethrough while preventing monovalent ions to pass therethrough. A power source is electrically coupled to each anode and the cathode, and is configured to apply a voltage across wastewater in the anodic chamber and the cathodic chamber, to thereby cause multivalent cations in the wastewater to pass through the multivalent cation exchange membrane.

In accordance with the principals of the present invention, an electrolytic generator and method of electrolytic generation are provided. An electrolytic stack includes of a first electrode, a second electrode, and a polymer-electrolyte membrane placed between the first and second electrodes. A first fluid passage provides fluid passage over the first electrode while a second fluid passage provides fluid passage over the second electrode. A third fluid passage provides fluid connection between the first fluid passage and the second fluid passage such that the fluid flows from the first fluid passage to the second fluid passage via the third fluid passage. An electronic current is provided between the first electrode and the second electrode when a voltage bias is applied to the electrodes.

A method of operating an electrochemical cell including introducing an aqueous solution into the electrochemical cell, applying a current across an anode and a cathode to produce a product, monitoring the voltage, dissolved hydrogen, or a condition of the aqueous solution, and reversing polarity of the anode and the cathode responsive to one of the measured parameters is disclosed. An electrochemical system including an electrochemical cell including an anode and a cathode, a source of an aqueous solution having an outlet fluidly connectable to the electrochemical cell, a sensor for measuring a parameter, and a controller configured to cause the anode and the cathode to reverse polarity responsive to the parameter measurement is disclosed.

Disclosed are systems and processes for the removal and conversion of pollutants in water. A system includes a set of electrodes with at least one electrode having an integrated catalyst material. The system is operatable in a first, electrodialysis mode in which one or more pollutants are separated from a feedwater stream, and a second electrolysis mode in which the separated pollutant(s) are catalytically converted into benign products by way of the catalyst material of the electrode. Electrodialysis and electrolysis are therefore carried out using the same unit.

A water ionizer includes a stacked electrolyzer and a flow switching device, with an inlet being separate from an outlet. Water entering an input regulator is distributed at a predetermined ratio before being supplied to an electrolyzer module to minimize acidic water to be discarded. Water supplied from the input regulator is directed to pass through the electrolyzer module in a crossing manner to delay flows of water to improve the efficiency of electrolysis. Electrolyzer cells are stacked on and fitted to each other to simplify an assembly process and improve convenience. Electrode plates of the electrolyzer module are fixedly fitted into a frame to facilitate an assembly process and improve a fabrication process. The input regulator and a flow switching output unit are connected via a connecting shaft to synchronize the operations thereof to obtain reliability.

Systems and methods for inhibiting growth of fungi and other organisms in air treatment systems such as air conditioners, humidifiers, dehumidifiers, and air washers. A pair of electrodes are brought into contact with liquid collected by a collection subsystem of the air treatment system. One of the electrodes includes a bio-inhibiting conductor. Electrical current is caused to pass between the electrodes, causing the bio-inhibiting conductor to be released into the collected liquid.
