Abstract |
Various ozone contacting systems were evaluated. A sparger incorporated into a six-stage contacting system was found to be the most practical system. Over 80 percent ozone transfer efficiency was obtained in secondary effluent with an applied ozone dosage of 50 mg/l. Despite efficient mass transfer with the system, an ozone consumption in excess of 50 mg/l was found to be necessary to accomplish the disinfection goal of 2.2 MPN/100ml effluent. The color goal of 10 units was achieved at an ozone dose of 10 mg/l. The use of carbon filtration prior to ozonation reduced the ozone dosage required for adequate disinfection to as low as 1 mg/l. Pretreatment of the sand and carbon filters was also briefly investigated. |
