A system and method is configured for inducing powder for pharmaceutical production. The system is configured to inducing the powder in a powder container into a powder flow pathway toward a branched lumen, wherein the powder container is a single use closed container, and wherein an air inlet is coupled to the powder flow pathway downstream of the powder container and upstream of the branched lumen. The powder is induced into a recirculation flow pathway toward a mix tank, wherein a pump assembly is located in the recirculation flow pathway. The powder is recirculated in the recirculation flow pathway toward the mix tank having a controlled air flow rate and recirculation flow rate.

A microbubble generation device comprises a liquid inlet (101), a gas inlet (104), a bubble flow outlet (103), and a gas-liquid mixing chamber (102). An air-permeable hole having an angle structure is provided at a gas-liquid interface of the gas-liquid mixing chamber (102), and a pointed end of the angle structure of the air-permeable hole points to a liquid flow direction. The bubbles generated by the device are extremely small in diameter, prolonging a duration the bubbles stay in the liquid phase, and enhancing gas-liquid mass transfer efficiency.

The system comprises: (a) a first sub-system comprising an ingress and an egress; (b) a second sub-system comprising an ingress and an egress; (c) an eductor mixing device comprising a first inlet in fluid communication with the egress of the first sub-system, a second inlet in fluid communication with the egress of the second subsystem, and an egress; (d) a tank assembly comprising an ingress and an egress, the ingress of the tank assembly being in fluid communication with the egress of the eductor mixing device; and (e) a transfer sub-system comprising an ingress that is coupled to the egress of the tank assembly. The transfer sub-system comprises a first transfer pump and a second transfer pump. In addition, method for operating the polymer dispersion system is disclosed.

A jet injection device that incorporates nanobubbles (ultrafine bubbles) in a mist includes: a two-fluid nozzle configured from a circular nozzle outer cylinder and an air connection tube integrally and perpendicularly connected to the nozzle outer cylinder; a nanobubble generation device that supplies the nozzle outer cylinder of the two-fluid nozzle with high-pressure nanobubble water; and a compressor that supplies the air connection tube of the two-fluid nozzle with high-pressure air. The gas-injected bubble water generated from the nanobubble generation device is pressure-fed to the nozzle outer cylinder of the two-fluid nozzle, and compressed air from the compressor is pressure-fed to the air connection tube of the two-fluid nozzle. In the two-fluid nozzle, the high-pressure gas-injected bubble water and the compressed air serve as a gas-liquid fluid mixture, and are injected at a high speed in mist form from a nozzle cylinder of the two-fluid nozzle.

A turbine system includes a foam generating assembly having an in situ foam generating device at least partially positioned within the fluid passageway of the turbine engine, such that the in situ foam generating device is configured to generate foam within the fluid passageway of the turbine engine.

An eductor includes an adjustable air inductor assembly connected to a source of outside air or other fluid. As liquid flows through a constricted orifice of the eductor, the venturi effect creates a vacuum or low pressure zone that draws inducting fluid through the inductor assembly and infuses such fluid into the liquid driven or transmitted through the eductor. The fluid inducted liquid is then discharged by the eductor into a body or contained volume of water. Improved aeration and fluid flow control, as well as reduced algae growth are achieved without extraneous mechanical equipment. Increased turbulent liquid flow is produced, for example, to more effectively clean dirt and debris from water recirculating swimming pools, fish tanks and similar environments.

A system for mixing, for example, salt with water to make brine, includes a mixing vessel removably mounted within a bulk vessel. The mixing vessel is provided with a divider/filtration wall separating a front portion, where solid granular material is provided and mixes with a liquid for purposes of dissolving the solid granular material into the liquid, and a rear portion. The mixing vessel is provided with an agitation pipe along a floor thereof, and is shaped to minimize settled granular material from collecting at the base of the mixing vessel. The divider/filtration wall serves to prevent overflow, includes one or more screens to allow liquid, but prevent granular material larger than the pore size of the screens, to pass from the front portion to the rear portion, and in the event of overflow, minimize turbulence in material passing over the divider/filtration wall, all of which promote delivery of a uniform distribution of dissolved material to the batch tank. In the case of salt brine production, a wireless salinity sensor can accurately measure salt concentration in real time at a variety of depths.
