A system for creating an oxidation reduction potential (ORP) in water employs a plurality of ozone supply units housed in separate enclosures. The ozone supply units feed into a manifold that 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 each ozone supply unit. The manifold includes a plurality of flow switches configured to transmit control signals to one or more controllers of each ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply units to generate ozone. The manifold also includes a plurality of fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply units into the water flowing through the fluid paths.

A mixer assembly for mixing an injected reductant with an exhaust gas comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The reductant inlet is positioned on a first side of the tubular housing and oriented to direct injected reductant along an injection access that extends transversely to a longitudinal axis.

The dispensing apparatus includes a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, and including at least two inlets opening into the central mixing passage, the inlets being associated with the same storage volume and open into the mixing passage at different positions along the flow direction.

The present invention relates broadly to microfluidic devices, particularly microfluidic devices optimised for the industrial production of nanoparticles such as liposomes. The device (101) comprises a substrate which extends between a distal end (107) comprising an outlet region (105) and a proximal end (108) comprising an inlet region (106). The inlet region comprises two substantially parallel outer channels (103a, 103b) for transport of a first fluid, said outer channels (103a, 103b) defined in part by a first outer wall (109a) and a second outer wall (109b) respectively, and a linear inner channel (104) for transport of a second fluid. The linear channel is disposed between the two substantially parallel outer channels. The outer channels (103a, 103b) and inner channel (104) extend from the proximal end (108) to a mixing chamber (102) which extends from the inlet region (106) to the outlet region (105). The mixing chamber (102) is in flow communication with the inner and outer channels (103a, 103b, 104) to receive the first and second fluids from the inner and outer channels (103a, 103b, 104) and the mixing chamber (102) has a uniform width (W) along its length substantially equal to the width (W1) between the outer walls (109a, 109b) of the two substantially parallel outer channels (103a, 103b).
