Abstract: A portable oxidant generator for generating a chlorine or chlor-oxygen solution suitable for sterilizing contaminated drinking water, thereby providing a water disinfection system and potable water. The oxidant generator includes an electrolytic chamber and a power supply or source. The chamber holds a salt brine solution such that the solution is in contact with an anode and cathode included in the chamber. The power supply provides electrical charge that is passed between the anode and cathode through the salt brine solution. In the preferred embodiment of the present invention, a combination manual pump/switch is activated and injects electrolyte into the cell chamber and electrolyzes the solution. In one embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes a gas pressure within the cell chamber thereby forcing the freshly generated oxidant solution from the cell. In another embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes gas pressure within the sealed cell chamber which acts against a spring loaded piston thereby increasing the chamber volume to minimize pressure buildup, and to maintain the electrolyte in contact with the anode and cathode throughout the electrolysis process irrespective of the orientation of the device. When electrolysis is complete, an electric valve is actuated that allows the freshly produced oxidant to be discharged in to the drinking container to provide disinfection and render the water potable.

Abstract: A system is provided for removing dissolved metals from industrial wastewater by electrocoagulation. The system includes an electrocoagulation reactor with a DC power supply having an insulation support enclosure with positive and negative electrode plates disposed thereon. The electrode plates are insulated for each other but remain in direct contact with the wastewater as it flows between the electrodes. The DC power supply induces opposite charges on alternate electrodes thereby generating an electric field between adjacent electrodes to cause the electrodes to ionize and go into solution for interaction with the contaminants in the wastewater as it flows through the reactor. The reactor is housed in a pressure vessel container so the exterior pressure on the reactor is higher than its internal pressure preventing leakage of fluids and oxygen and hydrogen gases produced in the reactor by decomposition of water. The pressure vessel allows higher operating pressures to retain higher concentrations of dissolved oxygen and hydrogen dispersed in the water for reaction with the contaminants. The electrical supply includes explosion proof connection housings for operation in hazardous environments. The system also includes a cyclone filter for separating the precipitated solid particles from the fluid and automatic control of the reactor by monitoring fluid flow, temperature, pH, and pressure.

Abstract: A method and system for electrolysis of water to increase the dissolved oxygen content, raise oxidation reduction potential, and perform direct oxidation of dissolved contaminants in situ. This is accomplished by an electrolytic catalytic oxidation (ECO) cell having an innovative configuration of electrodes in a cartridge designed to maximize water contact with an efficiently designed affecting system. The cartridge consisting of multiple mesh electrodes arranged transversely to imposed water flow electrolyzes passing water when energized. The mesh construction of the electrodes allows water flow to be essentially through the electrodes, with a narrow gap set up between cathode and anode to reduce voltage requirements of the system. The cartridge anodes are preferably plated with a mixed metal oxide such as iridium oxide and ruthenium oxide to catalytically improve the production of oxygen. The electrode cores are constructed of titanium, combining low electrical resistance with low activity, reducing metal loss during system operation.
