An ozone faucet switching structure includes a faucet body, a connecting member connected with the faucet body, an aerator mounted in the connecting member, and a control sleeve mounted on the connecting member. The faucet body has a water outlet pipe which is provided with a conduit which is externally connected with an ozone device. Thus, the control sleeve is movable on the connecting member to stop supply of the ozone when not in use to prevent the ozone from being mixed with the drinking water.

The disclosure relates to a method of performing ozonolysis or ozone-based oxidation on a liquid or emulsified reagent using a tubular falling film reactor with one or multiple tubes wherein the combined ozone and carrier gas flow is co-current.

An apparatus is configured to introduce ozone into water. The apparatus includes an ozone source that is configured to provide ozone. The apparatus further includes an air pump that is operatively coupled with the ozone source to provide an air stream mixed with the ozone at a pressure greater than atmospheric pressure. The apparatus further includes an ozone distributor pneumatically coupled with the air pump to introduce the ozone-mixed air stream into the water. The ozone distributor includes a porous tube set in a tortuous configuration.

A water treatment system can generate ozonated water using a vacuum operated injector with reduced vacuum switch lockup. The water treatment system includes an ozone generator, an ozone injector, a vacuum switch, and a pressure regulator. The ozone generator is configured to generate ozone. The ozone injector is coupled to the ozone generator via a hermetically sealed tubing, and the ozone injector is configured to inject the ozone into a water flow passing through the ozone injector. The vacuum switch is configured to operate the ozone generator based on a gaseous pressure inside the hermetically sealed tubing generated by the ozone injector. The pressure regulator is configured to regulate the gaseous pressure inside the hermetically sealed tubing to prevent the vacuum switch from trapped in a triggered state after the water flow stops.

A device, method, and system may recover, treat, and reuse condensate that is produced by climate control equipment. Minerals that are beneficial for both the intended use of the condensate and the formation of persistent ozone containing bubbles may be introduced into the condensate. An ozone containing gas may be introduced in to the condensate.

Systems, devices, and methods are presented for optimizing the formation of gas nanobubbles in a disinfecting solution. In an example system for treating contaminated water, a centrifugal pump draws the water from a reservoir and circulates the water in and through a circuit of elements including a mixing chamber in the pump, a pressure vessel, a backflow valve, a Venturi injector, and a pair of nozzles immersed in the reservoir. The system injects ozone-rich gas into the fluid to produce an aqueous solution containing a volume of gas nanobubbles. The nozzles release the gas nanobubbles into the reservoir, creating highly reactive compounds that destroy organic compounds and other contaminants in the water.

A water treatment system includes an ozone generator combined with an electrolytic chlorine generator in a compact, efficient and serviceable assembly. The system may include a modular and replaceable ozone generator, which allows a damaged or non-functional ozone generator to be quickly and efficiently replaced. In order to protect the ozone generator from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator. The water treatment system may further include an insulated electrolytic chlorine generator that mitigates or eliminates current leakage for efficient operation.

A device is provided for disinfecting water of a swimming pool, which includes an inlet for water from the swimming pool and an outlet for the water, an ozonation device, and a mixing section for ozone-containing water, wherein the ozonation device includes at least one UV light source for generating ozone, and an admixing unit for admixing the ozone to the water of the inlet, and the mixing section comprises a housing connected to the inlet, wherein the UV light source is arranged within the housing to emit UV light into the housing interior. The housing has deflecting surfaces for water protruding into the housing interior, which ensure a meandering flow within the housing. The device enables improved disinfection and can be designed to be more space-saving and visually appealing than conventional devices.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing and configured to generate ozone, an ozone inlet fitting removably coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.

A gas dissolution supply apparatus dissolves a gas supplied from a gas supply unit in a liquid supplied from a liquid supply unit to produce a gas dissolution in a gas dissolving unit, stores the gas dissolution produced in the gas dissolving unit in a gas dissolution tank, supplies the gas dissolution from the gas dissolution tank to a point of use, measures the flow rate of a part of the gas dissolution supplied to the point of use that is returned to the gas dissolving unit, and adjusts the flow rate of the liquid supplied from the liquid supply unit to the gas dissolving unit based on the result of the measurement.
