摘要： Provided is a UFB-containing liquid production apparatus that can efficiently produce a UFB-containing liquid with a UFB generation unit. The UFB-containing liquid production apparatus includes: a gas dissolution unit that produces a gas-dissolved liquid by dissolving a gas into a liquid supplied from a liquid supply unit; a UFB generation unit that generates UFBs in the flowing-in gas-dissolved liquid; and a circulation path that supplies the gas-dissolved liquid to the UFB generation unit and supplies a UFB-containing liquid produced by the UFB generation unit to the liquid supply unit. In the circulation path, there is provided a micro-bubble reduction unit that reduces an amount of micro-bubbles contained in the gas-dissolved liquid to flow into the UFB generation unit.

摘要： In order to efficiently produce a liquid containing ultrafine bubbles of a desired gas, an ultrafine bubble-containing liquid producing apparatus includes a gas dissolving unit that dissolves a predetermined gas into a liquid, and a UFB generating unit that generates ultrafine bubbles in the liquid in which the predetermined gas is dissolved. A CPU performs control under a first condition in a case of causing the gas dissolving unit to operate in a circulation route passing through the dissolving unit. The CPU performs control under a second condition different from the first condition in a case of causing the UFB generating unit to operate in a circulation route passing through the UFB generating unit.
