<p>PROBLEM TO BE SOLVED: To provide a method capable of producing stable nanobubble-containing water preservable over a long period, by efficiently generating a micro nubble group of a nano-level.SOLUTION: The present invention presents a production method of a nanobubble-containing water for generating a micro bubble group by physical stimulation in a collapse process by transferring raw material water except for a bubble of a large diameter to the collapse process 5 after supplying gas to the raw material water 1 as micro bubbles. The process of removing the bubbles of the large diameter from the raw material water, is executed by: standing the raw material water containing the bubbles in a storage part while transferring the raw material water in a lower part of the storage part to the collapse process; or removing the bubbles of the large diameter from the raw material water with a filter.</p> |
