An electrolyzing system for electrolyzing a brine solution is provided that includes a housing defining a brine compartment and a fresh water compartment. A first electrolytic cartridge is arranged in the brine compartment and includes an electrically charged electrode. The first electrolytic cartridge includes an inlet in fluid communication with the fresh water compartment and an outlet that is fluid communication with a dispensing system. An electrically powered pump directs fresh water from the fresh water compartment to the inlet of the cartridge. A control system is configured to direct electric power from a power supply to the pump when flow of fresh water from the fresh water compartment to the inlet of the cartridge is detected and configured to stop supplying electric power to the pump when flow of fresh water from the fresh water compartment to the inlet of the cartridge is not detected.

The invention relates to a water filtration with a process optimization method, which employ cartridges with conventional electrolytic cells that have electrolytic cells, modified with automated control systems for the purpose of manipulating, monitoring and performing maintenance strategies in a single device, either in mobile containers or in swimming pools, gutters, etc., in such a way that: the purification process of the liquid, preferably water, is increased, the speed of its processing is increased, a process that is conventionally performed manual way is automated; in addition to optimizing the materials used in the purification, the process minimizes the risks of infiltration of impurities in the organism by immersion in treated waters with high pollutant levels; finally the process decreases the formation of tartar in the containers.

Processes for the liberation of oxygen and hydrogen from water are provided allowing for mass scale production using abundant sources of catalyst materials. A metal oxide based anode is formed by the simple oxidation of metal in air by heating the metal for a specified time period. The resultant anode is then contacted with water and subjected to a voltage from an external source or driven by electromagnetic energy to produce oxygen at the surface of the anode by oxidation of water. These processes provide efficient and stable oxygen or hydrogen production.

Systems and methods for detecting and/or removing selenate from an aqueous selenate-containing solution are described. The method includes adding sufficient acid to the aqueous selenate-containing solution to acidify the aqueous selenate-containing solution; contacting the acidic aqueous selenate-containing solution with an underpotantial deposited copper-coated electrode; and removing selenate from the aqueous selenate-containing solution by forming copper-selenide on the underpotential copper-coated electrode.
