Provided is a UFB generating apparatus capable of manufacturing an ozone UFB-contained liquid with high purity and quality. To this end, in the UFB generating apparatus capable of generating UFBs containing ozone by causing film boiling in ozone water, a liquid contact portion to come into contact with the ozone water is made of a material with corrosion resistance to ozone water.

Provided is an ultra-fine bubble-containing liquid manufacturing apparatus that can suppress viable cell contamination inside a UFB generating unit. To this end, it is provided with an ultra-fine bubble generating unit that generates an ultra-fine bubble by making film boiling by a heating unit in a liquid in which a gas is dissolved, and a radiating unit that is capable of irradiating a wetted portion of the ultra-fine bubble generating unit with ultraviolet rays.

An all-ceramic diffuser supplies microbubbles of a narrow range of size to create a steady flow of bubbles of generally uniform size in an aqueous medium, such as process water in a wastewater treatment plant. The diffuser is formed of a porous body core, with pore sizes of e.g. 30 .Math.m or larger, an upper ceramic membrane that covers the upper surface of the body core, and has mean pore size of e.g., 3 to 15 .Math.m. A lower ceramic membrane covers the bottom surface of the body core, and has a finer pore size than the upper ceramic membrane, so that the capillary pore size of the smaller pores will act as a seal; consequently all of the air flow is through the upper ceramic membrane. A ceramic fitting connects the associated air supply with the porous body core which serves as plenum.
