An assembly for mixing and dispensing a multi-component fluid includes a sheath having first and second fluid chambers, a chamber coupler, and a flexible tip. The chamber coupler forms first and second fluid channels. Additionally, the flexible tip forms a mixing chamber with a variable mixing volume and an outlet. The flexible tip is coupled to the chamber coupler near a distal end of the sheath. In the presence of an activation force, the flexible tip is forced out of the sheath and positioned in a dispensing state with a maximum mixing volume. In the absence of the activation force, the flexible tip is housed within the sheath and positioned in a non-dispensing state with a minimum mixing volume such that the outlet is substantially closed.

A mixing chamber can be located between the outlet port and both the first inlet port and second inlet port, the mixing chamber configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port. An attachment structure can be located on the junction body and configured to attach the junction structure to the housing of the compounding device.

The invention provides an injector device for a water treatment apparatus, and a method of use.

In another aspect, a water treatment apparatus defines a plurality of parallel flow streams between the inlet of the apparatus and the at least one liquid treatment vessel. The injector device comprises an injection port for each of the plurality of parallel flow streams.

An inner plate assembly for arrangement between top and bottom plates of an applicator for applying fluid-based chemicals to traveling sheets of textile substrates includes a plurality of interlocking plate segments. Each interlocking plate segment includes an outer frame segment and one or more baffle member segments supported by the outer frame segment. Each interlocking plate segment further includes a first interlocking structure disposed at a first end thereof and a second interlocking structure at a second, opposite end thereof to facilitate end-to-end interlocking arrangement of the plurality of interlocking plate segments.

Disclosed herein are systems, methods, and apparatuses for managing abrasive media in cavitated fluid. One system includes a set of sensors in communication with the cavitated fluid in the processing tank and a processor coupled to the set of sensors. The processor is configured to determine a density of an abrasive media in the cavitated fluid in the processing tank and facilitate maintaining the density of abrasive media in the cavitated fluid in the processing tank at a level that is greater than or equal to a threshold level of abrasive media. A method includes determining a density of abrasive media in the cavitated fluid in the processing tank and maintaining the density of abrasive media in the cavitated fluid in the processing tank at a level that is greater than or equal to a threshold density of abrasive media. One apparatus includes modules for performing the method.

The present disclosure involves systems and methods for applying CO2 to concrete, which may be performed in-situ or through a separate, stand-alone process. According to another embodiment disclosed herein, a system and method for applying CO2 to one or more materials used in the production of concrete is also provided.

An ozone water treatment system using low energy. The present invention includes: a water pipe through which raw water, to be treated, is transferred and supplied while having energy; a gas injector for dispersing and injecting, in a micro bubble form, ozone gas to the raw water supplied and transferred from the water pipe; a low-energy using-type gas-liquid contact reactor for promoting a contact reaction between the ozone gas and the raw water within ozone mixed water supplied and transferred from the gas injector; and a discharge pipe for continuously transferring and discharging treated water having been reaction-treated. Therefore, since energy use during the ozone gas injection and the contact reaction can be remarkably reduced, processing costs can be reduced.

Methods and systems for converting inactive chemicals into active chemicals in-situ for treating oil and gas pipelines, other industrial systems, or sanitizing surfaces. Also, methods of treating an oil and gas pipeline including feeding an inactive additive through a first conduit and into a second conduit, the second conduit is in fluid communication with the first conduit and the oil and gas pipeline. The inactive additive is converted into an active additive within the second conduit and introduced into the oil and gas pipeline.

An exemplary manifold for a pharmaceutical ingredient compounding device can include a housing, at least one primary intake port including a primary valve to permit or block passage of at least one primary ingredient through the manifold, and a plurality of secondary intake ports. A first channel can be in fluid communication with the at least one primary valve and include an outlet port configured to outlet the at least one primary ingredient from the manifold. A second channel can be in fluid communication with a plurality of secondary valves and include an outlet port configured to outlet at least one of a plurality of secondary ingredients from the manifold. The first channel and second channel can be in fluid isolation from each other such that the at least one primary ingredient does not mix with the plurality of secondary ingredients within the manifold.

An exemplary compounding method of controlling a compounding device to prepare an admixture of at least two distinct material sources can include examining material source solutions for incompatibility of the ingredients and operating a first and a second pump to prevent one of the incompatible source solutions from entering a common flow path. The processing method can detect degradation of a fluid line by evaluating one or more of calibration error rate data, cumulative volumetric flow data, or cumulative pump operation data. The processing method can also selectively transfer a first group of source solutions using the first pump, receiving pump data from one or more sensors that sense actions of the pumps, applying fluid correction factors and calculating discrete pump movements, the pump movements being indicative of an amount of source solution displacement by a pump, and operating the pumps to selectively dispense the source solution amounts according to a preparation order.
