  • Patent number: 10710908
    Abstract: A water treatment device includes a grounding electrode having a planar flowing water portion that causes treatment target water to flow, a multiple of wire form high voltage electrodes provided parallel with the flowing water portion in a position distanced from the flowing water portion of the grounding electrode and to extend in a direction intersecting a flow direction of the treatment target water, and a blowing device that forms a gas flow that intersects an extension direction of the high voltage electrode and intersects an extension direction of an electrical discharge. This kind of configuration is such that even when water droplets adhere to the high voltage electrode, the water droplets are blown away by a pressure of the gas flow formed by the blowing device, and a spark discharge is restricted.

  • Patent number: 9115007
    Abstract: The present invention is directed to an assembly and a method of treating rainwater to produce potable water. A compact and easy-to-install apparatus is achievable as a result of a simple, yet highly effective sanitization method. Rainwater is entrained with a gas, and the entrained rainwater is irradiated with an ultraviolet (UV) light to fully sanitize the rainwater. The UV light is used during the irradiation of the entrained water and is also used to form a gaseous bactericide which is used to entrain the rainwater. None of the disadvantages of the prior art systems apply to any rainwater treatment systems which use this method. All of the connections between the component parts may be already provided for in this rainwater treatment unit, and consequently both installation and maintenance costs will be significantly reduced in comparison to the rainwater treatment systems which are known from the prior art.

    Abstract: A liquid treatment unit includes: a treatment tank provided with an inlet and an outlet, the treatment tank having a shape that allows a portion of liquid to be retained; a controller that controls supply of liquid into the treatment tank and ejection of liquid from the treatment tank; and a plasma generator generates plasma in the liquid inside the treatment tank. The plasma generator generates plasma while the controller stops supply of liquid and ejection of liquid. After the liquid has been treated, the controller resumes the supply of liquid, and causes the liquid to be ejected from the treatment tank while allowing a portion of the treated liquid to be retained inside the treatment tank.

  • Publication number: 20150136671
    Abstract: An enclosure 12) supports a water carrying tube (16) through which a flow of water to be sanitized passes. Water carrying tube (16) may be supported at each end by Venturis (24, 26) mounted in ends of a housing (12). One or more ultraviolet lamps (14) extend along tube (16). Air tubes (62a, 62b, 72) are connected to Venturi suction ports (30) or an external use (FIG. 7) and have openings (64) therealong are oriented very close to the ultraviolet lamps (14), with openings (64) facing the ultraviolet tubes (14) in order to draw ozonated air directly from near the surface of the ultraviolet lamps (14). Ultraviolet lamps (14) may be pulsed with high power pulses of a frequency and duration determined by an air flow rate through the air tubes (62a, 62b, 72) in order to maximize ozone production. An external Venturi suction port may also be provided.

  • Patent number: 9034184
    Abstract: This is a scalable water cleansing system intended for very low technology primitive communities buildable for between $600 and $1,000 of parts. A gravity feed system is contemplated with one or more of an initial filtering stage(s), a settling stage, a UV treatment stage, and an ozonator stage. A stand-alone power system with solar power needing no infrastructure is contemplated to enhance purification. The system can improve the worst of water quality, including for small groups; and under some conditions to end up with clean water of a quality found in developed countries with mature water systems. For water to the site in communities with low precipitation, the water brought in would be emptied into the initial stage of the water cleansing system, and the person who brought the water would draw from the last stage most or all of the amount of water carried in.

  • Patent number: 9034183
    Abstract: A method and apparatus of sanitizing drinking water to be dispensed from a water dispenser having a reservoir includes the steps of providing the ozone gas generator that generates an ozone gas stream, transmitting the ozone gas stream from the generator to the water dispenser reservoir, mechanically breaking up the ozone gas stream inside the reservoir to produce ozone gas bubbles, and using the ozone gas bubbles to disinfect water in the reservoir. The ozone gas stream can be mechanically broken up using a pump such as, for example, an impeller type pump.

  • Patent number: 9023215
    Abstract: A low energy water treatment system and method is provided. The system has at least one electrodialysis device that produces partially treated water and a brine byproduct, a softener, and at least one electrodeionization device. The partially treated water stream can be softened by the softener to reduce the likelihood of scale formation and to reduce energy consumption in the electrodeionization device, which produces water having target properties. At least a portion of the energy used by the electrodeionization device can be generated by concentration differences between the brine and seawater streams introduced into compartments thereof. The brine stream can also be used to regenerate the softener.

  • Publication number: 20150090670
    Abstract: A system for treating wastewater is disclosed that includes a series of interconnected reactor tubes. Each reactor tube comprises an outer cathode and an inner anode. The inner anode is positioned within the outer cathode. A voltage differential is applied across the inner anodes and the outer cathodes as wastewater flows between the inner anodes and outer cathodes. As the wastewater flows through the reactor tubes, chlorine based elements are generated to treat the wastewater. The system can include an injector to add chloride salts into the wastewater to generate chlorine based elements. The system can also include a feedback path to divert a portion of the wastewater with chlorine based elements back to the influent wastewater so that the chlorine based elements are mixed with the influent wastewater. The inner anode and the outer cathode can comprise non-donating conductive materials.
