The chart below shows ozone solubility vs. temperature for different ozone concentrations. The water pressure is at atmospheric (0 PSIG).
Several conclusions can be postulated from the chart. They are the following:
Ozone is extremely soluble! At 25 deg C, ozone solubility is 109 mg/l. The solubility of oxygen is 8 mg/l. Ozone is 13 times more soluble than oxygen.
The reason is because the ozone concentration being applied to the water is usually between 1-3% ozone. Ozone is also very reactive and instantly reacts with contaminants, or itself, in the water.
