Compositions and methods are provided for a system in which liquid carbon dioxide, or a mixture of liquid and gaseous carbon dioxide, is converted to solid carbon dioxide by exiting an orifice at a sufficient pressure drop, e.g., for delivery of carbon dioxide to a concrete mixture in a mixer.

A method and a generator for producing nanobubbles or nanodroplets at ambient conditions; the method comprising: providing a volume for accommodating a liquid; distributing a medium within the liquid, wherein the medium is provided to the volume at ambient conditions; generating an electric field using an electrode in the proximity of the volume for facilitating the generation of nanobubbles or nanodroplets; wherein the electrode and the liquid are not in direct electrical contact to prevent electrolysis occurring within the volume.

A dissolution system includes a dissolution line and a bypass line. The dissolution line fluidly couples a biocontainer, a pump, a cartridge, an upstream filter, and a downstream filter in a circulation loop. The bypass line is in fluid communication with the dissolution line at an upstream junction and a downstream junction such that the bypass line is in parallel relationship with the cartridge. A flow control system is configured to control the flow of fluid through the cartridge such that the flow of fluid through at least one of the dissolution line and the bypass line is selectively controlled based upon a pressure in the dissolution line downstream of the cartridge between the cartridge and the biocontainer.

Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium, such as a chromatography resin. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion during use while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.

A method and apparatus for carbonating a liquid in a pressurizable vessel, including first connecting a vessel with a carbon dioxide tank, wherein said vessel contains a liquid. A vessel can then be pressurized with carbon dioxide to a desired first pressure. A pump is activated to circulate the liquid through a hose out of the vessel to a fitting assembly and out of the fitting assembly back into the vessel. While the liquid is flowing through the fitting assembly carbon dioxide is introduced to the liquid at a second pressure level, wherein the second pressure is greater than said first pressure. After a pre-determined period of time the pump is deactivated and the carbon dioxide can cease to be introduced to the liquid flowing through the fitting assembly.

Disclosed are methods for continuous production of ozone strong water, the methods comprising the steps of injecting an acidification agent into a pressurized feed water to maintain a pH value of the pressurized feed water below 7, diffusing a two-phase mixture of O.sub.2-O.sub.3 gas) and recirculated water into a body of acidic pressurized water to dissolve ozone into the acidic pressurized water. The disclosed methods include simultaneously maintaining a start-up mode in an upper portion of the dissolution column that favors high efficiency of ozone mass transfer into the acidic pressurized water and a steady state mode in a lower portion of the dissolution column that favors a high concentration of dissolved ozone in the acidic pressurized water coexistent in the body of the acidic pressurized water, wherein an ozone concentration gradient is formed along a height of the body of the acidic pressurized water.

Disclosed are systems for continuous production of ozone strong water, the systems comprising an injection device that injects an acidification agent into a pressurized feed liquid, a diffuser device that injects ozone into a body of the acidic pressurized feed water, and injection nozzles each controlled by a valve that adjust a flow rate of the ozone strong water discharged from a dissolution column to match a flow rate of the acidic pressurized feed water fed to the dissolution column, thereby maintaining a start-up mode in an upper portion of the dissolution column that favors a high efficiency of ozone mass transfer and a steady-state mode in a lower portion of the dissolution column that favors a high dissolved ozone concentration coexistent in the body of the acidic pressurized liquid, wherein a concentration gradient of dissolved ozone is formed along a height of the body of the acidic pressurized liquid.

The invention relates to an agrochemicals pre-dilution unit comprising a mixing device that receives and mixes water and agrochemical. This unit carries out the mixing process by means of a plurality of pumps in fluid communication with the mixing device, which sends the prepared mixture a tank truck through outlet pipes. A plurality of bulks are installed in the unit and contain agrochemicals that are pumped in a controlled and precise manner to the mixing device, allowing a mixture of agrochemicals and water to be prepared with minimum human intervention. Also disclosed is the preparation of the liquid mixture controlled by a PLC, which enables an operator to obtain an accurate mixture without needing to intervene directly in the unit, since the operator can interact with the unit by means of a computer, such that such that the PLC controls all the devices in unit in order to prepare the mixture.
