An apparatus comprises a separator, a compressor, a mixer and a pump. The separator operates on an input gas mixture comprising carbon dioxide gas and one or more other gases, providing a separated carbon dioxide gas output. A compressor compresses the separated carbon dioxide gas output, providing a second output comprising at least one of gaseous carbon dioxide and liquid carbon dioxide. A mixer mixes the second output with liquid water under pressure to provide a third output comprising: at least one of liquid carbon dioxide and gaseous carbon dioxide; and water with dissolved carbon dioxide. A pump pumps the third output into an underground structure such that components of the third output react with available rock surfaces to form stable carbonates.

The present application relates to ultrasonic technology, and discloses an ultrasonic beer bubbling container with a good bubble foaming effect and less energy loss. The ultrasonic beer bubbling container comprises a cup body for containing beer and a base provided on the bottom of the cup body. The cup body and the base are separable; an ultrasonic vibrator is arranged in the base, and a through-hole is formed on the bottom of the cup body; wherein a part of the ultrasonic vibrator goes through the through-hole and extends to the cup body, thus to produce ultrasound and directly vibrate the beer so as to foam the beer.

A method for manufacturing beverage or other liquid containing bubbles uses a system for manufacturing bubble-containing liquid that includes: a bubble generating unit that generates fine bubbles in a liquid; a bubble collapsing unit that is connected to the bubble generating unit to collapse the fine bubbles contained in the bubble-containing liquid supplied from the bubble generating unit by making the bubble-containing liquid pass through the bubble collapsing unit and irradiating the bubble-containing liquid with ultrasonic wave; and a storage unit that is connected to the bubble collapsing unit to store the bubble-containing liquid supplied from the bubble collapsing unit. The method includes: a bubble generating step of generating the fine bubbles in the liquid by the bubble generating unit; a bubble collapsing step of generating superfine bubbles by forming an ultrasonic field by the bubble collapsing unit to collapse the fine bubbles contained in the liquid; and a storage step of storing the bubble-containing liquid containing the superfine bubbles by the storage unit. Consequently, beverage or other liquid containing the superfine bubbles can be manufactured.
