Abstract
An ultrafine bubble water manufacturing device includes a whirlpool pump, an ejector, a cascade pump, a branch portion on the downstream side of the cascade pump, a return path which communicates from the branch portion between the ejector and the cascade pump, a flow rate adjusting valve and a first ultrafine bubble manufacturing unit interposed in the return path, an emission path which communicates with the branch portion, a second ultrafine bubble manufacturing unit interposed in the emission path and a control device. The control device controls an air amount adjusting valve, the whirlpool pump, the cascade pump and the flow rate adjusting valve based on the measurement values of a concentration meter for the emission path and first and second pressure gauges and on the downstream and upstream sides of the cascade pump.
