A technique facilitates mixing of fluids for use in well treatment operations. According to an embodiment, a dry powder material, e.g. a friction reducer, may be thoroughly mixed into fluid or fluids associated with a well treatment operation. The powder material is combined with liquid, e.g. water, via a series of Venturi mixers arranged to thoroughly mix the materials. In some applications, the Venturi mixers are mounted on a modular unit which is readily moved to a desired wellsite. Additional modular units may be added to increase the amount of product being mixed according to the demands of a given well treatment operation, e.g. a hydraulic fracturing operation.

A carbonation machine with integrated water treatment. The carbonation machine may include a carbonation system for carbonating water in a bottle attached to a carbonation head of the system, a detachable water reservoir, configured to be mounted on a base with an outlet port to allow outward flow of water from the reservoir, piping connecting the outlet port of the water reservoir to transfer water from the detachable reservoir and to pour the water into the bottle, a pump for pumping water out of the water reservoir and transfer the pumped water via the piping, a controller configured to control the pump, and one or more water treatment components fluidically connected to the piping to apply water treatment to water flowing through the piping.

A method, apparatus, and system for mixing a compounded material. A first selected amount of a base part for the compounded material and a second selected amount of an activator part for the compounded material to form a total amount of the compounded material is determined. The first selected amount of the base part is pumped by a pump system from a set of base part sources connected to the pump system into a container. The second selected amount of the activator part is pumped by the pump system from a set of activator part sources connected to the pump system into a container. The base part and the activator part in the container are mixed by a mixing system for a predetermined amount of time that is sufficient to activate the compounded material for use.

A method of making a three-dimensional object by additive manufacturing from a blended resin including (i) at least one light polymerizable first component and, (ii) at least one, or a plurality of, second solidifiable components that are different from said first component, the method including: providing a first resin and a second resin, where the resins produce three-dimensional objects having different mechanical properties from one another when all are produced under the same process conditions; mixing the first and second resins with one another to produce the blended resin, the blended resin producing a three-dimensional object having mechanical properties intermediate between that of objects produced by the first and second resins when all are produced under the same process conditions; and dispensing the blended resin to the build region of an additive manufacturing apparatus; and then optionally but preferably producing a three-dimensional object from the blended resin in the apparatus.

A dispensing system includes a container containing a flowable base formulation to be dispensed, an additive mixing device, and an actuable pump engine which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body with an internal cavity, an additive ingredient within the cavity, and a flow path/mixing chamber between an input and an output. With each pump of the device the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices may be interchangeable for different formulations, and the mixing devices may be refillable.

In one configuration, a system for enriching a liquid with gas-bubbles is disclosed. The system may include at least one reservoir configured to temporarily store the gas-bubble enriched liquid. Each of the at least one reservoir may include an associated inlet port and an associated outlet port fluidically coupled with each other via a liquid-flow line. The system includes one or more pumps configured to cause movement of the liquid along the liquid-flow line, a gas supply feeding a gas (in one configuration, oxygen from a gas concentrator), and a gas-bubble generator provided on the liquid-flow line. The gas-bubble generator may be fluidically coupled to the gas supply to receive gas from the gas supply. The gas-bubble generator may be configured to generate a plurality of individual gas-bubbles of the gas received from the gas supply and mix with the liquid stream flowing via the gas-bubble generator.

A system for preparing solutions for chromatography application is disclosed. The system comprises a T-joint for preparing a buffer solution by mixing at least one first solution and a second solution. The T-joint receives the second solution from a solution supply unit connected to the T-joint. Further one or more low pressure pumps supply the one or more first solutions into the T-joint. The high pressure pump collects the buffer solution and delivers it to a chromatography apparatus.

The present invention relates to methods and devices for production of injectable foams, such as those used in the treatment of varicose veins and other venous disorders. The method requires the delivery or supply of foamable liquid sclerosing agent and a suitable gas or a gas mixture to a foam producing structure in which the liquid and gas are combined to produce foam, wherein the liquid is delivered independently of the delivery of gas. Devices for producing injectable foam comprise a foam producing structure in which liquid and gas are combined to produce foam, the structure comprising an inlet for liquid and gas and an outlet for foam; a liquid pathway in communication with the inlet; and a gas pathway in communication with the inlet, characterised in that the liquid pathway comprises a means for delivering liquid through the liquid pathway independently of gas delivery through the gas pathway. In preferred embodiments, the delivery of liquid and/or gas is controlled with volumetric pumps.

Providing a method for generating and releasing 1-MCP gas from a complex carrier through the use of a 1-MCP generator that enables the application of at least one physical, releasing force to a carrier complex and/or mixture comprising water and the carrier complex, or the interaction of steam with a carrier complex and/or mixture comprising water and the carrier complex, over a determined period of time.

The present disclosure relates to a method for adjusting grouting parameters in preparation of a ceramic composite fiber-based catalytic filter tube, and a method and a device for preparing a ceramic composite fiber-based catalytic filter tube. In the present disclosure, a loading reference value of a slurry is determined by a fiber length, a pH value, and a solid phase content of the slurry, thus evaluating a performance value of the slurry; initial working parameters for preparation are determined by comparing the loading reference value of the slurry with a preset value. During the actual preparation, a grouting amount is introduced to conduct conversion check on a quality of the slurry, so as to ensure a grouting pressure and a grouting pressure holding time during the grouting.
