Abstract:
The present invention relates to a portable device for generating ozone in water, purifying the water and making it drinkable. The device comprises a housing; at least two electrodes, including an anode and a cathode extending from the housing into the water and each having semi-rough or rough surfaces in contact with the water. The device also comprises a power supply operatively connected to the electrodes for generating between them a difference of potential creating a current and the hydrolysis of the water creating ozone that purifies the water. The electrodes may have a plate or a rode and tube configuration with a plurality of holes with rough edges. The roughness of the surfaces and of the edges of the holes leads to a coalescence of tiny hydrogen bubbles into larger hydrogen bubbles. The hydrogen may be also removed by absorption in a conductive material and regenerated for reuse.
Abstract:
A special reaction apparatus includes a reactor which receives a target reactant to be treated and which is placed on an insulator with a grounded earth terminal, and an electromagnetic coil including a high-voltage insulated electric wire and solenoidally wound on the reactor, one of the ends of the electromagnetic coil being electrically isolated, and the other end being connected through an insulated electric wire to an output terminal of an AC high potential generator together with an electrode disposed in the reactor. Under a condition in which an AC high potential is applied to apply a very small electric current, the special reaction apparatus utilizes a composite function of an AC magnetic field induced by the electromagnetic coil, an AC electric field induced by the electrode, and an electrochemical electrode reaction produced between the electrode and the reactant to be treated.

Abstract:
The invention features a flow-through capacitor system that achieves enhanced power efficiency by sequential control and actuation of at least two or more flow-through capacitor cells within the flow-through capacitor system. Alternatively or in addition, power efficiency is enhanced by integrating the purification stages of the system, for example, by placing more than one cell within a single cell casing. Preferably, integrated stage flow-through capacitors are controlled sequentially.
Abstract:
A fluid treatment chamber is provided for the deactivation of microorganisms in a fluid. The fluid treatment chamber comprises a housing and an electrode assembly. The housing comprises a fluid inlet for receiving fluid to be treated and a fluid outlet for allowing treated fluid to be retreived. The electrode assembly is located within the housing and comprises at least two electrodes for generating an electric field there between. The electrodes have opposing convex electrode surface sections defining there between a biconcave treatment zone for treatment of the fluid by the most intense electric field generated by the electrode assembly. The treatment zone comprises a channel between the opposing convex electrode surface sections through which the fluid is to flow to receive treatment. The channel width tapers towards a vertical midsection of the channel due to the convex configuration of the opposing electrode surface sections.
Abstract:
A spiral electrodeionization device comprising flow paths within helical cells, which form a path-lengthening maze. Impermeable barriers between membranes prevent the feed and concentrate flows from mixing. Seals along or between portions of the flow path may define a multi-stage device, a separate feed device and /or concentrate flows for different stages, and/or direct the feed and concentrate flows along preferred directions which may be co-current, counter-current or cross-current with respect to each other. Bands (BB) in the concentrate compartments may channel scale-forming species along separate paths in different regions so that scaling does not occur, and the separation of species may be enhanced by arranging the feed flows along an axial direction through layers of different monotype resins that enhance species transport into one region of the concentrates and/or inhibit transport of the complementary sealant species in that region.

Abstract:
A self-powered buoyant electrolysis device, for placement into a reservoir of a contaminated electrolytic solution, such as water, containing halide ion, such as chloride ion, to electrolyze the water, thereby disinfecting or sterilizing the contaminated reservoir of water. Contaminated reservoirs of water can be water containers filled with river water and other outdoor sources, or can be contaminated municipal water held in kitchen containers, cooling systems, water tanks, cisterns, etc. The buoyant body allows the electrolysis device to float on or remain buoyant in the reservoir water. Preferred devices are small and portable, and comprise reliably productive electrolysis cells that are powered by batteries. A means for propulsion of the device can also be provided, and is preferably a pump that pumps the water through the electrolysis cell.
