There is provided an inline saturator system and method for gas exchange with an aqueous-phase liquid. The system comprises a pressure vessel, configured to receive a first liquid and a first gas from external sources and to discharge a second liquid and a second gas from the pressure vessel, and a gas infusion device situated within the pressure vessel. The gas infusion device is configured to receive the first liquid and first gas, to facilitate gas exchange therebetween, producing the second liquid and the second gas, and to discharge the second liquid and second gas into the pressure vessel. The system further includes a recirculation system configured to direct a portion of liquid within the pressure vessel back into the saturator device, where injection of the redirected liquid into the gas infusion device forces the first liquid into the gas infusion device for the gas exchange.

In some embodiments, a method of making hydrated bone material is provided, the method comprising providing a bone material in a chamber, the bone material comprising a plurality of shaped bone particles or macroparticles, each of the plurality of shaped bone particles or macroparticles having a substantially uniform size, shape and porosity; and mixing each of the plurality of shaped bone particles with liquid in the chamber under pressure so as to cause the liquid to hydrate each of the plurality of shaped bone particles to form uniformly hydrated bone material. In some embodiments, a device for mixing a bone material with a liquid is provided.

An extrusion equipment adapted for supercritical foaming and mixing of a raw material includes a mixing unit, an injection unit for injection of supercritical fluid into the mixing unit, and an extrusion unit for extrusion of the raw material. The mixing unit includes a tube for input of the raw material, and a propelling screw rod and an auxiliary screw rod that are disposed side by side in the tube and that cooperatively compress and propel the raw material. The auxiliary screw rod rotates at a speed at least twice that of the propelling screw rod and in a direction opposite to that of the propelling screw rod.

The present invention relates to a mixing apparatus. A production unit produces a working fluid that is in a supercritical state or a subcritical state. A storage unit stores a material. A dissolving unit dissolves the material in the working fluid. A mixer mixes the material together in the presence of the working fluid. A material feed valve opens or closes a flow passage through which the material is to pass to be fed from the storage unit into the dissolving unit. A working fluid inflow valve opens or closes a flow passage through which the working fluid is to pass to flow into the dissolving unit from the production unit. A mixer inflow valve opens or closes a flow passage through which the working fluid and the material are to pass to flow into the mixer from the dissolving unit.

Provided is an ultrafine bubble generating apparatus that generates ultrafine bubbles by generating film boiling by causing a heater provided in a liquid to generate heat, the ultrafine bubble generating apparatus including: an element substrate including a first heater that generates the film boiling in the liquid and a second heater that is arranged adjacent to the first heater, in which the first heater and the second heater are driven in different timings.

A vertical low-pressure reactor with stirred tank for leaching polymetal minerals and concentrates of lead, copper, zinc, iron and/or the mixtures thereof, in a solid-gas-liquid three-phase suspension system. The low-pressure vertical reactor with stirred tank consists of: a cylindrical vertical container with three or four deflectors evenly distributed across the 360; a stirring system made up of two impellers coupled to a rotary shaft, that provides adequate reaction and interaction of the metal species of interest; a space of the volume of the reactor, corresponding to 20% to 35% of the total volume of the container, located at the top of the reactor and which acts as a gas chamber that provides a continuous feed of oxygen; and a system of coils placed on the outside or inside surface of the reactor to ensure efficient heat-transfer reactions and controlled kinetics.

A method for controlling pressure in a blending apparatus includes sealingly coupling a blade platform to a rim of a vessel including foodstuffs to form a blending chamber. The blade platform includes a blade assembly. The method includes injecting fluid via an opening defined within the blade platform into the blending chamber while the blade platform is sealingly coupled to the vessel. The injection of fluid causes a change in pressure in the blending chamber. The method includes rotating blades of the blade assembly to process the foodstuffs in the blending chamber. The method includes introducing air into the blending chamber to decrease a difference between the pressure within the blending chamber and a pressure external to the blending chamber. The method includes decoupling the blade platform from the rim.

A method of manufacturing a self-expanding fire-fighting foam solution is disclosed. Here, the method can include purging air from a container, wherein the purging is performed via flowing an inert gas into the container, such that substantially inert environment is created within the container. In addition, the method can further include dispensing or filling a pre-determined amount of foam concentrate into a container, dispensing or filling a pre-determined amount of water into the container, and mixing the foam concentrate and water within the container, wherein the mixed foam and water within the inert container provide the self-expanding fire-fighting foam solution and having a pH ranging from about 6.8 to 7.8 moles per liter.

Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.
