Abstract
The apparatus includes: a producing unit that generates ultrafine bubbles in a liquid supplied from a liquid introducing unit to produce an ultrafine bubble-containing liquid containing the ultrafine bubbles, and delivers the ultrafine bubble-containing liquid; a liquid delivering unit that delivers the ultrafine bubble-containing liquid to an outside; a buffer tank that receives the liquid delivered from the producing unit and delivers the liquid to the liquid delivering unit; and a controller that controls the delivery of the ultrafine bubble-containing liquid from the buffer tank to the liquid delivering unit such that, if the producing unit stops operating, an ultrafine bubble-containing liquid accumulated in the buffer tank is delivered to the liquid delivering unit to enable the liquid delivering unit to deliver the ultrafine bubble-containing liquid to the outside.
