A beverage carbonation apparatus having a spring loaded bottle mounting mechanism to catch and hold an upright bottle when inserted therein and form an operative seal for carbonation, the bottle mounting mechanism including a user-actuable release handle assembly to release the bottle and reset the loading spring.

A beverage carbonation apparatus having a spring loaded bottle mounting mechanism to catch and hold an upright bottle when inserted therein and form an operative seal for carbonation, the bottle mounting mechanism being pivotable to release the bottle and reset the loading spring.

The invention relates to a method for producing a beverage in portions, wherein a beverage concentrate portion is mixed with a water portion, said water portion being mixed with carbon dioxide prior to being mixed with the beverage concentrate. The invention additionally relates to a device for producing a beverage in portions, wherein a beverage concentrate portion is mixed with a water portion, said water portion being mixed with carbon dioxide in a static mixer prior to being mixed with the beverage concentrate.

A combined water aeration and filtration unit (WAFU), having a tank with a vent section at a top of said WAFU and above an aeration section above a filtration section at a bottom of said WAFU. The vent section has one or more demisters and one or more vents for detraining water and providing a dry air exit from said WAFU. The air section has a water inlet ending in a spray nozzle near the top of the aeration section to turn incoming dirty water into water droplets and a forced air blower on a side or top of the aeration section for blowing air through said water droplets in rate sufficient to remove volatile organic compounds and precipitate manganese and iron. The aeration section also has one or more annular rings or partially annular baffles on an inside wall of the tank to force water from said inside wall into an interior of the tank. Thus, no water escapes aeration. A backwash collection trough and backwash water outlet are positioned above the filtration section for removing dirty backwash water from the unit. The filtration section has one or more filters therein and a drain and clean water outlet near its bottom for egress of clean water from said WAFU.

An aerator for treating wastewater is configured to produce air bubbles to mix and circulate wastewater within a treatment facility. Additionally, the aerator is configured to inject additive into the wastewater at the same time as the air bubbles are being produced, so that roiling of the air bubbles and/or circulation induced by the air bubbles rising within the water column facilitates mixing of the additive with the wastewater.

This application relates to an ultra fine bubble production apparatus for producing ultra fine bubbles. The apparatus may include a container portion including a liquid and a gas, and a drive portion for pressurization in the container portion. In the pressurization, the time required for the pressure to reach the maximum pressure from the start of the pressurization can be 2.0 milliseconds or less, and the maximum pressure can be 4.00 MPa or more.

A method and apparatus for producing hydrogen gas whereby a nanobubble generator introduces nanobubbles at a concentration of at least 10.sup.7 nanobubbles per cm.sup.3 into an electrolytic cell comprising a pair of electrodes and a hydrogen-containing, electrolyzable liquid, and the electrolytic cell is operated to produce hydrogen gas.

An aerator has a submersible mixing tube having a water inlet and an aerated water outlet. An aspirating tube penetrates the mixing tube between the water inlet and the aerated water outlet, the aspirating tube having an air outlet introducing air into the mixing tube and an air inlet drawing in air from atmosphere above a water surface. The mixing tube has an outboard motor lower unit engagement to engage a lower unit of an outboard motor in use such that a propeller thereof locates entirely within the mixing tube with a midsection of the outboard motor extending from the engagement. As such, the propeller of the outboard motor lower unit thrusts water past the air inlet thereby creating suction at the inlet to draw air via the mixing tube to mix with the water to expel a plume of aerated water.

An apparatus has a plurality of gas transfer membranes. The apparatus floats in water with the membranes submerged in the water. To treat the water, a gas is supplied to the membranes and is transferred to a biofilm supported on the membranes or to the water. Gas is also used to supply mixing or membrane scouring bubbles to the water. The mixing or scouring bubbles can be provided by a cyclic aeration or other gas supply system, which optionally provides gas at a variable pressure to the membranes in parallel or series with an aerator. Condensates can be removed from the membranes, and exhaust gasses from the membranes can be monitored, optionally through one or more dedicated pipes.

The invention relates to an ultrafine bubble (UFB) generator and a method for generating UFB. The invention also provides an ultrafine bubble-containing liquid and a production method of the liquid. An ultrafine bubble generator is prepared by combining (A) a sophorolipid containing acidic sophorolipid and lactonic sophorolipid in a ratio (mass ratio) of 78:22 to 100:0, (B) a free fatty acid or salt thereof, and (C) a gas generation component.
