An inline gas/liquid infusion system featuring an electronic control logic and subsystem having a signal processor configured to: receive signaling containing information about a liquid pressure of an incoming liquid provided from a pump to an inline gas liquid absorption device and about a gas pressure of an incoming gas provided to the inline gas liquid absorption device; and determine corresponding signaling containing information to control the liquid pressure of the incoming liquid provided from the pump to the inline gas liquid absorption device in order to provide real time adjustable set point output levels of gas absorption in the inline gas liquid absorption device, based upon the signaling received.

The object of the invention is to achieve a more efficient and complete mix between a liquid and gas by means of a system comprising 4 components in order to carry out a reaction or mixing process that improves the contact, and as a result, the reaction or mixing between a liquid and a gas, followed by a recovery stage of the gas that does not react during the reaction or formation of said mixture. This gas is recycled to the reaction or mixing zone, permitting the improvement of the efficiency and the cost of the reaction or mixing process between the liquid and the gas.

A method of producing a carbonated beverage comprising a blend of water and syrup having a predetermined final carbonation level. The method includes the steps of: introducing CO.sub.2 into a flowing stream of a product blend comprising water, syrup and dissolved oxygen, such that CO.sub.2 is dissolved in the product blend; deaerating the CO.sub.2-containing product blend by introducing the blend into a vented atmospheric vessel, the interior of which is at ambient pressure with a headspace maintained above the surface of the liquid within the vessel, whereby dissolved oxygen is released from the product blend and vented from the vessel; pumping the deaerated product blend from the vessel, wherein the deaerated blend includes dissolved CO.sub.2 at an intermediate carbonation level less than the final carbonation level; and carbonating the deaerated product blend to the final carbonation level downstream of the vented vessel to produce a carbonated beverage for subsequent packaging. A system for performing the method is also provided, as well as a method of producing a beverage using nitrogen deaeration.

The present invention provides subsurface irrigation systems and air injection mechanism and microbubble generating mechanism. The systems of the present invention are operable to provide an evenly distributed air microbubbles in a stream of fluid (e.g., subsurface irrigation water) to evenly provide gas therein (e.g., oxygen for plants receiving the irrigation water along an entire length of an irrigation line). The microbubble generating mechanism may use pressure generated from flow of fluid to cavitate the fluid and thereby distribute gas microbubbles in the fluid. In irrigation examples, the resulting air infused water delivers an effective amount of oxygen to the roots of the irrigation crops.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

The invention provides methods and compositions for carbonation of cement mixes using pressurized carbon dioxide delivered to the mix.

Embodiments include a system for generating nanobubbles in a solvent, including a device for generating a reverse and forward flow in the solvent, wherein the solvent has one or more gases dissolved in it; and a Tesla valve fluidly coupled to the device, wherein the device pushes the solvent through the Tesla valve one or more times alternatingly in a forward and reverse direction to generate nanobubbles of a desired concentration and size. Aspects include a method for generating nanobubbles in a solvent, including filling a device with a desired solvent containing one or more gases dissolved in it; wherein the device is capable of generating a reverse and forward flow in the solvent, and wherein a Tesla valve is fluidly coupled to the device; and using the device to push the solvent through the Tesla valve one or more times alternatingly in forward and reverse directions to generate nanobubbles.

A manufacturing apparatus for calcium carbonate can fix carbon dioxide as calcium carbonate safely and without releasing carbon dioxide to the air. A manufacturing apparatus for calcium carbonate includes a reaction tank, a slurry supplying means, a fine bubble generation device, and a circulation line that includes a space where a slurry can flow and that is formed through the reaction tank and the fine bubble generation device. The reaction tank has the airtightness to not release carbon dioxide. The slurry supplying means supplies the slurry containing calcium hydroxide into the reaction tank. The fine bubble generation device includes a fine bubble generation tube with a tubular shape that is formed of a porous body. Carbon dioxide is blown as fine bubbles into the slurry flowing in the fine bubble generation tube by supplying a carbon dioxide gas into the fine bubble generation device from the outside.
