PCT No. PCT/JP93/00629 Sec. 371 Date Jul. 12, 1993 Sec. 102(e) Date Jul. 12, 1993 PCT Filed May 12, 1993 PCT Pub. No. WO93/23340 PCT Pub. Date Nov. 25, 1993.An apparatus for mixing a gas with a liquid and for dissolving the gas in the liquid comprises a throttled section (12) formed in a fluid flow passage, a gas inlet (18) provided slightly downstream of the throttled section (12), a widened section (16) which is continuous with the throttled section (12), a mixing section (20) provided downstream of the widened section (16), for mixing the gas introduced from the gas inlet (18) with the liquid in the fluid flow passage, and a nozzle section (24) provided on the outlet of the mixing section (20) for outputting the liquid with the gas dissolved therein. The gas is dissolved in the liquid in the mixing section by pressurizing the liquid in the mixing section. The apparatus is useful for dissolving ozone into a liquid, for dispersing bubbles in a liquid and for floating small particles in a liquid.
