A method of mixing a pharmaceutical solution including adding a gas into an interior compartment of a mix bag to form a headspace. The interior compartment of the mix bag includes a top portion and a bottom portion. The headspace adjacent to the top portion contains gas. The method includes adding a solvent into the mix bag, and establishing a bubble column in the interior compartment by activating a recirculation assembly. The recirculation assembly includes a connecting pathway operably coupled to a recirculation pump. A first end of the connecting pathway is coupled to a top gas recirculation port and a second end is coupled to a bottom gas recirculation port of the mix bag such that the recirculation pump draws the gas from the headspace and delivers the gas to the interior compartment via the bottom gas recirculation port. The method includes adding a solute into the mix bag.

An apparatus for delivering a wet concrete mix to a product mold, where the apparatus comprises a hopper configured to retain a fresh concrete mix, a source of treated water having a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the water, a water transport coupling the source of treated water with the hopper, a valve interposed within the water transport for selectively releasing the treated water into the hopper, and a mixer in communication with the hopper for mixing the treated water with the fresh concrete mix to yield an infused wet concrete.

A fine bubble generating apparatus has a storage tank, a liquid feeding unit suctioning and feeding liquid stored in the storage tank, a gas discharge unit discharging gas into the liquid which is being fed by the liquid feeding unit, and a storage tank. The gas discharge unit includes a gas discharge member with pores having pore diameters of 1.5 μm or less, and a base member having a groove formed in a surface contacting the gas discharge surface of the gas discharge member. The liquid feeding unit moves the liquid along the gas discharge surface of the gas discharge member by causing the liquid to flow in a flow channel enclosed by the gas discharge surface of the gas discharge member and the groove of the base member such that a velocity relative to the gas discharge member is not less than 1 msec.

A nanobubble-infused liquid is mixed into a dry concrete mix to form an infused wet concrete, where the nanobubble-infused liquid includes a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the liquid. The nanobubble-infused liquid is preferably liquid water infused with a desired concentration of carbon-dioxide (CO.sub.2) nanobubbles sized within a certain prescribed range. The infused wet concrete is then transported to the mold of a concrete products forming machine to form a molded product that has enhanced qualities including increased carbon capture within the resulting concrete product, improved curing times, increased flowability, self-healing, and improved release from the product mold.

A nanobubble nozzle includes a body; an inlet for receiving a liquid; an outlet for discharging the liquid with nanobubbles; a forward channel extending through the body from the inlet to the outlet for transmitting the liquid, the forward channel having a venturi throat; a return channel extending from the outlet to recirculate a portion of the liquid and mix it with a gas to form a two-phase mixture; and an inlet port connecting the return channel to the venturi throat. The liquid flow through the throat creates a suction drawing the two-phase mixture into the throat. A cross-sectional area of the forward channel decreases from the inlet to the throat and increases from the throat to the outlet so that an internal pressure lower than an external pressure outside the body and lower than a vapor pressure of the liquid flowing through the throat is provided at the throat.
