<;P>;PROBLEM TO BE SOLVED: To provide a nanobubble-containing water production apparatus and method which cause no clogging of a discharge port of a nozzle even when nanobubbles are discharged for a long time. <;P>;SOLUTION: The nanobubble-containing water production apparatus comprises a first tank 21 which prepares microbubble-containing water by making suspended solid-containing water contact microbubbles, discharge piping 38 which removes suspended solid-microbubble complexes where microbubbles adhere to suspended solids in the suspended solid-containing water, and a nanobubble generator 24 which shears the microbubble-containing water from which the suspended solid-microbubble complexes have been removed by the discharge piping 38 to prepare nanobubble-containing water. <;P>;COPYRIGHT: (C)2009,JPO&INPIT
