The confined plunging liquid jet reactor with modified downcomer includes a downcomer having an upper end, an open lower end, and a gas inlet for receiving gas. A plurality of longitudinally-extending baffles and/or a sieve are mounted in the downcomer, adjacent the open lower end thereof. A nozzle is mounted on the upper end of the downcomer for receiving a pressurized liquid from an external source to generate a liquid jet. The liquid jet impinges on liquid contained within the downcomer creating turbulence and bubbles with the gas entrained therein. The open lower end of the downcomer is positioned within a receiving tank holding a reservoir of the liquid such that a portion of the mixture of the liquid and the gas exits the open lower end of the downcomer to flow into the receiving tank.

A micro-reactor system for contacting fluids is described. The system comprises a first microfluidic channel structure for guiding a first fluid to at least one output nozzle thus generating a first sub-flow, a second microfluidic channel structure for guiding a second fluid to at least a second output nozzle thus generating a second sub-flow, said first output nozzle being aligned with said second output nozzle and arranged for contacting the first sub-flow and the second sub-flow. The micro-reactor comprises at least a third microfluidic channel structure for at least a third, inert, fluid generating at least a third sub-flow arranged to be positioned adjacent at least the first and/or the second sub-flows so as to act as a wall between said first and/or second sub-flows.

A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

A jet-mixer for a fluid mixing system includes a housing including a mixer port formed in an inner surface of the housing, and a rotor rotatably disposed in the housing, the rotor including a rotor blade, wherein the rotor includes a first angular position in the housing restricting fluid flow through the mixer port, and a second angular position allowing fluid flow through the mixer port, wherein, in response to rotation of the rotor in the housing, the jet-mixer is configured to inject a first fluid jet through the mixer port into the passage of the fluid conduit that has a pulsed velocity profile.

An apparatus for premixing fluids to form dialysate for an extracorporeal blood treatment includes at least a first feed portion for supplying at least a first fluid from at least a first fluid reservoir, at least a second feed portion for supplying at least a second fluid from at least a second fluid reservoir, a premixing portion being configured to premix fluids supplied via the feed portions in counter flow to form a fluid mixture and at least one drain portion for draining the fluid mixture premixed in the premixing portion as dialysate. A method carries out appropriate steps. In a conductivity measurement along the drain portion the conductivity of the premixed fluid mixture is measured by means of a digital filter adapted to be parameterized based on at least two state variables of the premixing process at least in two phases with a first predictive phase and a second corrective phase.

An example mobile drilling fluid plant includes a plurality of intermodal containers each exhibiting a length, a width, and a height compliant with universal shipping container dimensions and configurations dictated by the International Organization for Standardization, wherein the plurality of intermodal containers include a plurality of fluid storage containers and one or more fluid mixing containers, one or more pumps in fluid communication with the plurality of fluid storage containers and the one or more fluid mixing containers, and one or more flexible hoses fluidly coupled to the one or more pumps and placing the plurality of fluid storage containers in fluid communication with the one or more fluid mixing containers.
