Systems and methods are described for dissolving ammonia gas in deionized water. The system includes a deionized water source and a gas mixing device including a first inlet for receiving ammonia gas, a second inlet for receiving a transfer gas, and a mixed gas outlet for outputting a gas mixture including the ammonia gas and the transfer gas. The system includes a contactor that receives the deionized water and the gas mixture and generates deionized water having ammonia gas dissolved therein. The system includes a sensor in fluid communication with at least one inlet of the contactor for measuring a flow rate of the deionized water, and a controller in communication with the sensor. The controller sets a flow rate of the ammonia gas based on the flow rate of the deionized water measured by the sensor, and a predetermined conductivity set point.

A dispenser includes a dock configured to be fixed in place at a use device and a solid product holder configured to be removably secured to the dock. The dock has a first portion including a fixation element that is configured to fix the dock in place at the use device and a second portion including a receiving structure. The solid product holder includes a retaining structure, a base, and a support structure. The retaining structure is configured to removably secure the solid product holder to the receiving structure at the second portion of the dock. The base defines a plurality of apertures that form an open area at which the liquid is received at the solid product holder. The support structure extends from the base and defines an internal volume for holding the solid product at the solid product holder.

The gas dissolution chamber has a vent opening, a liquid inlet, and a liquid outlet, the bypass member has a gradually contracting section, a throat part, and a gradually expanding section which are connected in sequence from a bypass inlet to a bypass outlet; the bubbler is connected to the liquid outlet, the bypass inlet or bypass outlet of the bypass member is connected to the liquid inlet to supply liquid into the gas dissolution chamber, and the throat part is connected to the vent opening or a gas storage space in the gas dissolution chamber.

A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.

Conventional ozone water is still insufficient in the removal rate and cleaning ability of resist required in today's semiconductor manufacturing field, and it does not fully meet the expectation of further improvement in the effects of sterilization, deodorization, and cleaning in the fields such as cleaning of foodstuffs, cleaning of process equipment and tools, and cleaning of fingers, as well as in the fields such as deodorization, sterilization, and preservation of freshness of foodstuffs. The above problem can be solved by defining the values of a plurality of specific production parameters in the production of ozone water into specific ranges.

A transportable system includes a utility cart with an aqueous ozone solution (AOS) supply unit mounted to the utility cart. The utility cart includes a base with wheels, vertical support members extending from the base, and an upper shelf supported by the vertical support members. The AOS supply unit includes an enclosure coupled to the utility cart between the base and the upper shelf, the enclosure including openings for a water inlet and an aqueous ozone solution outlet. The AOS supply unit further includes one or more ozone generators and a fluid mixer disposed within the enclosure. The fluid mixer is fluidically coupled to the one or more ozone generators and configured to inject ozone generated by the one or more ozone generators into water received from a water source via the water inlet to produce an aqueous ozone solution that is output via the aqueous ozone solution outlet.

Systems and methods are described, which relate to the control of additive dispensers to provide defined amounts of one or more additive compounds to water to produce customized water. A given additive dispenser may include multiple inputs and/or outputs. Predefined water profiles may be stored in memory. A given water profile may define the amounts of additives to be delivered by the additive dispensers to achieve desired water characteristics. A controller may determine actual water characteristics of input water based on corresponding sensor data, and may compare the actual water characteristics to desired water characteristics in order to determine the amount of additive or additives that should be delivered to the input water to achieve the desired water characteristics. The additive dispensers may be network-enabled and may include transceivers configured to receive instructions related to production of customized water from a user device.

A multi-cone, multi-stage spray nozzle includes a nozzle body, a valve stem with a first valve head, and a second valve head attached to the first valve head. The first valve stem is biased into a closed position against a valve seat of the nozzle body by a bias device. The second valve head is continuously open. Upon the application of a first fluid pressure, which is less than a threshold fluid pressure, the bias device maintains the valve stem in the closed position while the second valve head is continuously open. And upon the application of a second fluid pressure, which is at least as great as the threshold fluid pressure, the valve stem moves to an open position while the second valve head remains continuously open.

A gas solution manufacturing device 1 includes a gas supply line 2 configured to supply a gas as a raw material of a gas solution, a liquid supply line 3 configured to supply a liquid as a raw material of the gas solution, a gas solution production unit 4 configured to mix the gas and the liquid together to produce the gas solution, a gas-liquid separation unit 5 configured to perform gas-liquid separation of the produced gas solution into a supplied liquid to be supplied to a use point and a discharged gas to be discharged through an exhaust port, and a gas dissolving unit 6 provided in the liquid supply line 4 and configured to dissolve the discharged gas resulting from the gas-liquid separation in the liquid. The gas dissolving unit 6 is configured with a hollow fiber membrane configured with a gas permeable membrane.
