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:
A system and method for processing impure water is achieved by using ozone for the separation and removal of certain contaminants and for further purification of the water. According to one embodiment, a gas comprised of ozone and air is injected into the impure water. The gas is converted to bubbles which are used as a flotation reagent while the ozone portion of the gas provides for the disinfection and deodorization of the liquid. The impure water is constantly supplied into an upper portion of a working volume or column of fluid contained within a processing unit. At the same time the gas is supplied into the bottom part of the same fluid column through one or more diffusers. Due to their porosity the diffusers generate the bubbles of this ozone-based gas so that each bubble has a predetermined size. ˙
Abstract:
A dissolved ozone delivery system comprises a generator for producing gaseous ozone, a bottle for holding a liquid suitable for receiving the gaseous ozone, flow conduits for delivering the gaseous ozone to the bottle and dissolving the ozone into the liquid to form an ozonated liquid, and a multicomponent bottle closure sealing device. The multicomponent bottle closure sealing has several discrete gas flow passageways for channeling the ozone gas into the bottle, venting undissolved gas and delivering the ozonated liquid to an exterior surface for decontamination thereof or medical instruments for sterilization or use in medical or dental procedures.
Abstract:
A water filter-pitcher includes a water pitcher with at least two chambers separated by at least one filter, and an ozone generator to generate ozone for sanitizing at least internal surfaces of said two chambers.
Abstract:
An apparatus for treating water with ozone includes a first conduit (26) and a passageway (36) for admitting ozone into the first conduit (26). There is a second conduit (48) having a top, and inlet connected to the first conduit and an outlet. There is a third conduit (52) having a top and a vertical portion (56) extending downwardly adjacent to the outlet (58) of the second conduit. The third conduit (52) has a bottom with an outlet below the outlet (58) of the second conduit. The outlet (58) of the second conduit is not more than one-third the distance from the top of the third conduit (52) to the outlet of the third conduit. There is a passageway (50) connecting the third conduit (52) to the first conduit (26) above the outlet (58) of the second conduit. The passageway (50) is sized to permit a reduced flow of water through the third conduit (52) compared to the flow through the second conduit (48) and provides means for gas discharged from the outlet of the second conduit to rise through the vertical portion (56) of the third conduit to increase dissolving of the gas in the water. There is a pump (22) for pumping water with sufficient force from the outlet (58) 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:
This ozone appliance for the professional dental office and other medical applications introduces dissolved ozone into dental and surgical operatory water lines. This dissolved ozone can not only disinfect water and water lines; it can also reduces gum bleeding, gingivitis, bad breath, teeth stains and oral bacteria. Additionally, it can aid in wound disinfection in surgery and attack microbial contamination of water from dental and surgical oparatory water lines and attached hand pieces and dispensing devices by automatically killing waterborne germs and destroying biofilms where germs can hide and grow. It can, therefore, be used to disinfect water lines in dental operations and for other medical applications such as providing liquid containing ozone for cleaning and disinfecting skin prior to surgery (and tissue exposed during surgery). Further, a unit connected to operatory water lines can give an audible or other alarm if the water becomes unsafe.
