The solubility of Ozone
depends on the water temperature and the Ozone concentration
in the gas phase:

If oxidable
chemicals are present in the water, larger amounts of Ozone
will dissolve to satisfy the demand. One limiting factor is
the efficiency of the mass transfer device used. When using
Venturi more turbulence and smaller bubbles facilitate
better mass transfer. When using Bubble Diffusers, the water
column should be at least 16 ft. high. Higher concentrations
of Ozone in water cause more vigorous
oxidation of even more resistant organic compounds.
