what is the solubility of oxygen in water when sparged with pure oxygen?
Injecting 90% pure oxygen instead of air enhances the theoretical maximum solubility of oxygen in water from approximately 18 milligrams per liter (mg/L), at a sparge pressure of 30 pounds per square inch gage (psig) to 75 mg/L at the same pressure.
