A carbonation system for a beverage appliance or machine that can include a liquid chamber and a carbonation chamber separated from the liquid chamber by a wall of the carbonation chamber is disclosed herein. In some implementations, the liquid chamber is defined by a liquid tank (e.g., a water tank), and the carbonation chamber is defined by a carbonation tank. The carbonation system can move liquid (e.g., water) from the liquid chamber to the carbonation chamber and introduce carbonating gas (e.g., carbon dioxide) into the carbonation chamber to create a carbonated liquid (e.g., a carbon dioxide water dissolution, such as carbonated water, sparkling water, or seltzer).

The present invention relates to a gassing unit for bubble-free introduction of a process gas into a liquid located in a reactor, wherein the gassing unit comprises at least: a first gas receiving chamber and, spaced therefrom, a second gas receiving chamber for receiving a process gas, the two gas receiving chambers being connected to one another via at least two two-dimensional, gas-conducting diffusion membranes comprising hollow fibers spaced apart from one another and at least partially fixed to one another; a receptacle for a gas supply on at least one of the gas receiving chambers; a receptacle for a shaft on at least one of the gas receiving chambers;
wherein the gassing unit for gassing the liquid in the reactor can be supplied with process gas via the gas supply receptacle, can be set into a rotational movement via the receptacle for the shaft and can form a convection flow within the reactor via the rotational movement of the gassing unit in the liquid. Furthermore, the present invention relates to a method for gassing a process liquid, a gas-liquid reactor comprising a gassing unit according to the invention, and the use of a gassing unit according to the invention for supplying biological cultures with process gases.

An air diffuser includes: a bottom panel provided in a horizontal direction in a tank in which water is filled; an air diffusion body installed to cover the bottom panel from above; and air diffusion holes arranged to penetrate through the air diffusion body, gas fed to a gap between the bottom panel and the air diffusion body is discharged into water through the air diffusion holes, and an air diffusion region of the air diffusion body where the air diffusion holes are arranged has a width equal to or larger than 10 mm and smaller than 120 mm.

A fluid supply apparatus for inducing cavitation and Coanda effects, includes: a cavitation generator configured to allow an introduced fluid to flow while rotating along a propeller-shaped wing so as to generate microbubbles in the fluid; and a Coanda generator disposed in front of the cavitation generator and having a plurality of Coanda generating protrusions arranged at regular distances so that, as a fluid passing through the cavitation generator to contain microbubbles passes through a passage between the Coanda generating protrusions, a velocity increases and the pressure decreases, thereby causing a Coanda effect in which the fluid flows along a surface of an object.

A stabilized, gas-infused liquids containing ultra high concentrations of infused gas, produced by: generating a gas-infused liquid in a sealed vessel under a high pressure of at least 20 psi; stabilizing the gas-infused liquid by passing the liquid while still under the high pressure through a tubular flow path arrangement which compresses the infused gas into nano bubbles in the liquid; infusing an additional amount of the gas into the stabilized liquid by injecting the same, while still under high pressure, back into the sealed pressure vessel along with more of the gas; and again stabilizing the liquid by again passing liquid, while still under the high pressure, through the tubular flow path arrangement to thereby form the additional amount of infused gas into nano bubbles in the liquid.

A method for filtering a gas comprises passing a gas through a compartment of a filter assembly, the filter assembly comprising: an inlet opening; a first outlet opening; a casing comprising polymeric film and bounding the compartment, the compartment communicating with the inlet opening and the first outlet opening; and a first filter at least partially disposed within the compartment. The method further comprising forming a first seal across a first section of the casing at a location between the inlet opening and the first filter to form a first sub-compartment within the casing and severing the casing at a first location.

Systems and methods for aeration and mixing processes are disclosed.

A microbubble generator and a laundry treating device. The microbubble generator includes: an air dissolving tank, having an air dissolving cavity defined therein, and an inlet and an outlet configured to allow water to flow in and out, the inlet being located above the outlet; a baffle, provided in the air dissolving tank, at least partially located between the inlet and the outlet in a horizontal direction, and provided with a gap and/or a through hole; and a cavitator, provided outside the air dissolving tank and connected with the outlet, or provided at the outlet.
