ABSTRACT:
The invention relates to injecting ozone through at least one injecting means operating with a pressure drop of at least about 35 psi into a pressurized stream of aqueous solution, allowing the ozone injected stream to travel or flow at a velocity of at least about 7 feet per second for a distance sufficient to dissolve at least about 70% of the ozone injected and mixing the resulting ozonated stream with an aqueous stream solution to be ozonated.
