Also disclosed herein is a microfluidic system comprising the present microfluidic mixer, and a pump for introducing a first and a second fluid reactants respectively into the first and a second input chambers.

A carbonation tower for containers of household appliances, more specifically for appliances for the automatic preparation of instant drinks, which has been developed to provide more optimized operation and use and efficient than those achieved with the known similar. Said carbonation tower including a substantially elongated body included of at least one pipe provided with at least two holes and said pipe secured to a base including at least a nozzle, said cooperating base further including a lid of a lower compartment; said lid further including at least one toroidal contoured rib cooperating with at least one lower nozzle of the container, and wherein the water and the carbon dioxide are sucked by the upper edge of the pipe and/or the holes and expelled in a path orthogonal to the suction axis through the at least one nozzle.

An apparatus for mixing fluids within a pipe is provided. In one embodiment, the apparatus includes a fluid mixing device with a pipe having a pipe wall and an axial bore for conveying fluids through the pipe. The fluid mixing device also includes a sleeve disposed about the pipe and a cavity provided between an exterior surface of the pipe and an interior surface of the sleeve. The cavity and the axial bore of the pipe are in fluid communication with one another via an opening through the pipe wall. Additional systems, devices, and methods are also disclosed.

This disclosure is directed to the regulated injection of a chemical(s), solution(s) or material(s) hereafter referred to as chemicals into stormwater runoff, other surface waters or other fluid streams to promote the removal of a pollutant(s) or to alter the properties of the water. Specifically, and depending upon the types of chemicals injected, the physical, chemical and/or biological properties of the water can be altered. The invention provides a passive system to alter stormwater runoff or other surfaces. The system may be deployed at a remote site, such as a construction site, and implemented with minimal or zero external power requirements.

A shotcrete nozzle assembly comprising: a tubular body including a body sidewall defining a central passageway extending along a central longitudinal passageway axis, and water dispensing bores extending through the body sidewall and including: first and second sets of water dispensing bores positioned such that outlet openings thereof defined in an inner face of the body sidewall are disposed in a respective one of longitudinally spaced-apart first and second transversal planes extending perpendicularly to the passageway axis, at least some of the water dispensing bores being oriented such that the central bore axes thereof extend in a non-radial direction relative to the passageway axis, and such that an orthogonal projection of the central bore axes of the first and second sets of water dispensing bores onto one of the transversal planes forms first and second projected central bore axes which intersect each other at a first non-zero angle.
