Abstract:
An apparatus for treating water with ozone includes a first conduit and a passageway for admitting ozone into the first conduit. There is a second conduit having a top, an inlet connected to the first conduit and an outlet. There is a third conduit having a top and a vertical portion extending downwardly adjacent to the outlet of the second conduit. The third conduit has a bottom with an outlet below the outlet of the second conduit. The outlet of the second conduit is no more than one-third the distance from the top of the third conduit to the outlet of the third conduit. There is a passageway connecting the third conduit to the first conduit above the outlet of the second conduit. The passageway is sized to permit a reduced flow of water through the third conduit compared to the flow through the second conduit and provides means for gas discharged from the outlet of the second conduit to rise through the vertical portion of the third conduit to increase dissolving of the gas in the water. There is a pump for pumping water with sufficient force from the outlet of the second conduit such that a stream of water and undissolved gas therefrom reaches a point at least one-half the distance from the outlet of the second conduit to the outlet of the third conduit.
Abstract:
An apparatus and method for enhancing dissolution of gases in liquids by ejecting the gas-liquid mixture through nozzles in a reaction vessel. The nozzles are pressurized, sized and directed to produce micro-fine gas bubbles in the liquid and to initiate rotational flow of the gas-liquid mixture in the reaction vessel. The small bubble size and rotational flow maximizes the time the gas is in contact with the liquid. The apparatus and method are used to increase the dissolution of ozone gas into aqueous solutions to increase the decomposition of aqueous-based organic compounds, precipitation of heavy metals, and destruct and/or deactivate enteric viruses, enteric bacteria, and protozoans. An alternative embodiment mixes the gas with the liquid prior to ejection through the nozzles.
Abstract:
Periphyton filtration is a known method for performing bioremediation of polluted water, removing nutrients from the influent on which the attached algae thrive. The present system improves upon this method by adding a strong oxidizer to the influent, and, in some cases, to the effluent, to make organically bound nutrients available to a target culture of periphyton or aquatic plants to reduce the population of undesirable microinvertebrates, to make organically bound nutrients available to the periphyton, and to reduce the level of toxic compounds. A particular embodiment comprises ozonating the water. A pesticide may be added to control insect populations.
Abstract:
A water purification system for a swimming pool, pond, aquatic mammal tank, spa or fountain, which is simple to operate, low in maintenance, and highly reliable. The system takes advantage of synergistic benefits derived from the combination of ozonation and electrolytic chlorination in the same system. Combining both of the technologies of Ozonation and Electrolysis allows as in-site production of at least one of chlorine dioxide that is used as a disinfectant agent for treating water reservoirs.
Abstract:
Original seawater is supplied to a pre-treatment equipment, and a flocculated material produced by exerting a magnetic force and injecting ozone is removed by filtration. The seawater pretreated by the pre-treatment equipment is supplied to a reverse osmosis membrane module. Concentrated salt water discharged from the reverse osmosis membrane module is supplied to an electrodialyser unit. The concentrated salt water discharged from the electrodialyser unit is supplied to an evaporator. In the evaporator, the concentrated salt water is evaporated to dry solid salt. A part or all of desalted water discharged from the electrodialyser unit is returned to the reverse osmosis membrane module. Permeated water discharged from the reverse osmosis membrane module and evaporated water obtained by the evaporator are supplied as potable water.
Abstract:
Wastewater is remanufactured with ozone in a series of mixing vessels. The ozone is dispersed to both a top and a bottom portion of each mixing vessel, but in different amounts. This creates an electrical potential difference across the height of each mixing vessel which significantly improves the oxidation of organic carbon-based impurities and eliminates H2S and bacteria. Sludge and solids floating to the top of each mixing vessels are removed, as well as sludge and solids settling to the bottom of the mixing vessels. When oil and gas well wastewater is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.
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.
Abstract:
A system for and method of sanitizing water and waterway surfaces using ozone gas is disclosed wherein water is circulated from a water reservoir in a water ozonation loop means. Ozone is generated by an ozone generator and dispensed into the circulating water by an ozone feed means. In some embodiments the ozone is generated from gas in the water reservoir and dispensed into the water ozonation loop means at a venturi tube. A controller is provided for activating an ozonation cycle. In some embodiments, the ozonation cycle includes the actuation of a circulating water pump for a cycle interval, and the actuation of an ozone generator during an ozone generation interval, which is less than the cycle interval.
Abstract:
A faucet for dispensing a fluid includes a spout, a pull-out spray head removably coupled to the spout and including an outlet, and a valve assembly in fluid communication with the outlet. 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:
The apparatus capable of producing ionized water may have a simplified structure to prevent water from being lost and also prevent an electrode and ion diaphragm from being damaged. The apparatus may selectively supply alkaline water and acidic water. The apparatus includes an ionization electrolytic cell configured to contact the raw water only with one electrode disposed on one or more inner walls of the ionization electrolytic cell to contact the raw water only with either of the anode and cathode, an ionization water controller controlling the ionization electrode according to the discharge of the ionized water, and a switch applying a signal from a user to the ionization water controller.
