This paper reviews traditional methods of ozone injection for wastewater treatment with special reference to the gas‐liquid contacting system. Operating characteristics and process efficiencies for the different systems described are compared. Recommendations are made about process selection for wastewater treatment by coronation. The cost of ozone generation for wastewater treatment from air, used on a once‐through basis, is compared with recycled oxygen, with special reference to Canadian parameters. Capital investment costs for various plant capacities are presented and operating costs, as a function of oxygen lost during recycling, are calculated.
