An apparatus for mass producing monodisperse microbubbles includes a microfluidic flow focusing device, which includes a dispersed phase fluid supply channel having an outlet that discharges into a flow focusing junction, a continuous phase fluid supply channel having an outlet that discharges into the flow focusing junction, and a bubble formation channel having an inlet disposed at the flow focusing junction. The configuration of the flow focusing junction is such that, in operation, a flow of dispersed phase fluid discharging from the outlet of the dispersed phase fluid supply channel is engageable in co-flow by a focusing flow of continuous phase fluid discharging from the outlet of the at least one continuous phase fluid supply channel under formation of a gradually thinning jet of dispersed phase fluid that extends into the inlet of the bubble formation channel.

Continuous mixing in a static mixer possible can be used to add one kind of particles (such as an enzyme granular product) in a small amount to a larger amount of a different kind of particles (such as a powder stream of detergent powder), even if the powder characteristics are substantially different, with substantially no damage to the enzyme particles and with a high degree of homogeneity.

A mixer comprises a tubular housing defining a longitudinal axis along which exhaust gas flows. Injected reductant flows along an injection axis that extends at a non-parallel angle to the longitudinal axis. A first flow guide element extends across and blocks a portion of the tubular housing and includes a first aperture extending therethrough. The first flow guide element is positioned upstream from the reductant inlet such that exhaust gas flowing through the first aperture is impinged by the reductant. A second flow guide element is positioned downstream from the first flow guide element and fixed to the first flow guide element to define a mixing chamber in which injected reductant and exhaust gas mix. An intermediate wall is integrally formed with one of the first and second flow guide elements. The other of the first and second flow guide elements is fixed to the intermediate wall.

A transportable system for creating an ORP in water includes an ozone supply unit and a manifold housed in separate enclosures on a wheeled frame. The ozone supply unit feeds into the manifold which contains a plurality of fluid paths and has one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of the ozone supply unit. The manifold includes flow switches configured to transmit control signals to one or more controllers of the ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply unit to generate ozone. The manifold also includes fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply unit into the water flowing through the fluid paths.

System and method for dispensing a flowable product are provided. The system includes a mixing chamber having a first inlet, a second inlet and an outlet. The mixing chamber of the system contains a mixing element capable of motion. The system also includes a paste located in an enclosure configured to flow into the mixing chamber via a first channel connected to the first inlet, and a flowable medium configured to flow into the mixing chamber via a second channel connected to the second inlet. The mixing chamber is configured to mix the paste and the flowable medium using the mixing element, thus, producing the flowable product that may be output via the outlet.

Disclosed herein is a device and methods for enhancing oil separation from produced water. One such method includes mixing a multiphase fluid having at least a water phase and an oil phase with a flotation gas, according to at least one operating condition, so as to produce an enhanced multiphase fluid having bubbles of the flotation gas therein. The oil phase is then separated from the water phase using a separator. At least one property associated with the enhanced multiphase fluid is monitored. The operating condition is adjusted as a function of the monitored property so as to increase a percentage of the oil phase separated from the water phase by the separator over a percentage of the oil phase that would be separated from the water phase without adjustment of the operating condition.

A robot end effector (100) for dispensing an extrudable substance (102) comprises a chassis (110), a static mixer (101), and cartridge bays (122), extending from the chassis (110). Each of the cartridge bays (122) is shaped to receive a corresponding one of the two-part cartridges (104). Fluidic communication between the selected one of the two-part cartridges (104) and the static mixer (101) is established when the cartridge bays (122) are rotated about an axis (190) to a predetermined orientation with respect to the chassis (110). The robot end effector (100) also comprises a dispensing valve (130), attached to the chassis (110), and a head assembly (150), comprising an inlet manifold (152). The inlet manifold (152) is configured to selectively supply compressed air from a pressure source (199) to contents of a corresponding one of the two-part cartridges (104).
