Abstract:
An apparatus and a method for an ozone-based treatment of polluted water are disclosed. The apparatus and the method generally comprise three stages. The first stage is an ozone treatment stage wherein the polluted water is treated with ozone gas. The second stage is a gas-liquid separation stage wherein excess non-dissolved gases, from the ozone treatment stage, are removed from the water whereby the water exiting the gas-liquid separation stage is substantially saturated with dissolved gases and substantially free of non-dissolved gases. The last stage is a membrane filtration stage wherein the gas-saturated water generally undergoes micro-filtration or ultra-filtration. Microbubbles formed during this final stage generally prevent the accumulation of particles and pollutants on the surface of the membranes and/or inside the openings or pores thereof; thereby acting as a self-cleaning mechanism for the membrane filter.

Abstract:
Methods and systems for reducing a redox active contaminant in a waste stream in a waste treatment system involve performing a unit process of the waste treatment system by contacting redox active contaminant in the waste stream with oxyhydrogen-rich gas generated on-site by an oxyhydrogen gas generator that implements water dissociation technology. The oxyhydrogen gas generator involves applying a pulsed electrical signal to a series of closely spaced electrodes that are submerged in the waste stream to produce oxyhydrogen-rich gas from a water component of the waste stream. Operation of the oxyhydrogen gas generator in the waste stream may accomplish one or more unit processes for waste treatment, such as oxidation, stripping, floatation, disinfection, conditioning, stabilization, thickening, and dewatering, among others.
Abstract:
Water treatment apparatus for supplying ozonated water to appliances, such as clothes washing machines. First and second water aspirators include respective first and second Venturi tubes. One aspirator is designed for a relatively higher water flow rate, and the other is designed for a relatively lower water flow rate. A valve selectively directs water from a water inlet to a water outlet through either the first or the second water aspirator. Ozone from an ozone generator is drawn either into water flowing through the first Venturi tube or water flowing through the second Venturi tube, depending on the position of the valve. A water flow sensor includes a microphone physically connected for sensing a sound characteristic of operation of a Venturi tube. A controller effects a time delay for maintaining activation of the ozone generator for a predetermined time duration even after water flow has ceased.
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.
Abstract:
Disinfection device for installation into a water dispenser having an accumulating reservoir for drinking water filled from an external source of drinking water, including a flow-through ozone-air mixture generator provided with an air pump for external air delivery via an air filter to the ozone-air mixture generator. An output of the ozone-air mixture generator is connected with a delivery pipeline for delivery of ozone-air mixture or air inside the delivery pipeline. An electromechanical ultrasonic frequency irradiator is mounted on the delivery pipeline to generate ultrasonic oscillations in the pipeline walls and in water filling the pipeline, and a program control unit controls operation of the ozone-air mixture generator, air pump and electromechanical irradiator for disinfection and cleaning of inner surfaces of the pipeline and water therein. A method for the disinfection of water dispensers is also disclosed.
Abstract:
An ozone supply module for supplying ozonated water to an appliance that typically includes: an appliance module housing having a water inlet; a water outlet; and an electrical connection for receiving electrical power; a proton exchange membrane cell positioned within the housing; and a water conveying system within the module housing and operably connected to both the water inlet and water outlet. The water conveying system is typically configured to allow water to flow through the deionizing resin and into contact with the proton exchange membrane cell. The module and the proton exchange membrane cell receive electrical power from a home appliance when the module is operably connected to the appliance. The module produces water that contains (dissolved) ozone to be delivered to a chamber within the appliance when the module is in the engaged position with the appliance. The appliance is typically a residential appliance.
Abstract:
Disclosed is a new form of reactive ozone and techniques for producing nanobubble suspensions of the reactive ozone. The bubbles entrap a high concentration of ozone, with the ozone orienting a net negative charge outwards and a net positive charge inwards.

Additionally, the faucet includes a fluid treatment assembly configured to output a treatment into the fluid. The faucet further comprises a first flow path and a second flow path.
Abstract:
A modular ductwork assembly decontaminates an air stream circulating within a heating, ventilation and air conditioning (HVAC) system. The assembly includes one or more of (a) an ionizing module for removing particulates from the air stream, (b) a sterilization module for neutralizing airborne pathogens present in the air stream, (c) an ozone treatment module for neutralizing pathogens or odoriferous or gaseous constituents or volatile organic compounds (VOCs) present in the air stream, optionally (d) baffles for slowing and disrupting the flow rate and promoting turbulence in the air stream traveling through the modules, optionally (e) a fan module for directing a treated air stream, optionally (f) an ozone sensor, optionally (g) a monitoring or ozone control means, and optionally (h) a means of delivering and repurposing generated ozone. Each of the modules is arranged substantially adjacent to at least one of the other modules.
