In one configuration, a hydroponic system for enriching a liquid with gas-bubbles is disclosed. The system may include at least one reservoir configured to temporarily store the gas-bubble enriched liquid. Each of the at least one reservoir may include an associated inlet port and an associated outlet port fluidically coupled with each other via a liquid-flow line. The system includes one or more pumps configured to cause movement of the liquid along the liquid-flow line, a gas supply feeding a gas (in one configuration, oxygen from a gas concentrator), and a gas-bubble generator provided on the liquid-flow line. The gas-bubble generator may be fluidically coupled to the gas supply to receive gas from the gas supply. The gas-bubble generator may be configured to generate a plurality of individual gas-bubbles of the gas received from the gas supply and mix with the liquid stream flowing via the gas-bubble generator.

A paint production system produced from pigment pastes and vehicles without prior adjustment. The system includes a volumetric dosing module endowed with automatic volumetric calibrators, at least one continuous processing module that includes a rotary mechanism that moves at least one tank between a mixing station, a continuous adjustment station integrated into a filling station, a cleaning station jointly with a manifold cleaning solvent mist generator and a control center that sends commands to be executed in the volumetric dosing module and continuous processing module units from a set of instructions in a computer program.

The present invention provides a method of manufacturing an emulsion that is more excellent in monodispersibility by a membrane emulsification method. The manufacturing method for an emulsion of the present invention is a manufacturing method for an emulsion, including circulating a mixed liquid containing a water phase and an oil phase in a circulation circuit including a plurality of tanks, a porous body, a liquid-delivering means, and circulation pipes configured to connect the tanks, the porous body, and the liquid-delivering means so that the mixed liquid passes through the porous body a plurality of times, wherein a tank to supply the mixed liquid to the circulation pipes toward the porous body and a tank to recover the mixed liquid that has passed through the porous body are different tanks.

Systems, devices, and methods are presented for optimizing the formation of gas nanobubbles in a disinfecting solution. In an example system for treating contaminated water, a centrifugal pump draws the water from a reservoir and circulates the water in and through a circuit of elements including a mixing chamber in the pump, a pressure vessel, a backflow valve, a Venturi injector, and a pair of nozzles immersed in the reservoir. The system injects ozone-rich gas into the fluid to produce an aqueous solution containing a volume of gas nanobubbles. The nozzles release the gas nanobubbles into the reservoir, creating highly reactive compounds that destroy organic compounds and other contaminants in the water.

A mixer unit comprising a mixing chamber is disclosed. In one example, the mixing chamber comprises a de-agglomerator with a de-agglomeration shaft with de-agglomeration paddles, and a mixer with a mixer shaft with two or more mixing paddles that are arranged for mixing and impelling particles and powders in an upstream direction towards the de-agglomerator, whereby the de-agglomeration shaft is arranged above, and in parallel with said mixer shaft, so that all particles will be impelled towards the de-agglomerator, each time particles are lifted. A first portion of the mixing chamber may also have an inner profile adjacent and curved about an upper part of the de-agglomerator and is arranged to guide particles and powders impelled by the mixing paddles over the de-agglomeration shaft and into a liquid spray.

A mixing apparatus includes a phosphoric acid aqueous solution supply, an additive supply, a tank, a phosphoric acid aqueous solution supply path and an additive supply path. The phosphoric acid aqueous solution supply is configured to supply a phosphoric acid aqueous solution. The additive supply is configured to supply an additive configured to suppress precipitation of a silicon oxide. The phosphoric acid aqueous solution supply path is configured to connect the phosphoric acid aqueous solution supply with the tank. The additive supply path is configured to connect the additive supply with the tank. The additive is supplied while fluidity is imparted to the phosphoric acid aqueous solution supplied from the phosphoric acid aqueous solution supply into the tank.

Various implementations include an aeration device. The aeration device includes a venturi tube and an outlet tube. The venturi tube has an outlet port and an air intake port. The outlet tube has a first end coupled to the outlet port of the venturi tube, a second end opposite and spaced apart from the first end, and an intermediate portion disposed between the first and second ends of the outlet tube. The intermediate portion is helically shaped and extends around a helical axis of the intermediate portion. The intermediate portion extends at least one rotation about the helical axis.

A method for producing a mixture of oil and fluid food product includes placing a funnel into a pressure tank such that a stem of the funnel extends at least halfway down into the pressure tank. The pressure tank is flushed with nitrogen. Oil flows into the pressure tank through the funnel. A flow of nitrogen into the pressure tank is maintained through a side inlet of the pressure tank. Oil is dispensed from a pressure tank into the transfer line flowing a flow of fluid food product from a batch tank. The dispensed oil is dispersed into the flow of fluid food product in a inline shear mixer creating oil-in-fluid food product droplets. The oil-in-fluid food product droplets flow to the batch tank with the flow of fluid food product. The oil-in-fluid food product droplets are distributed in a volume of fluid food product in the batch tank.
