| Abstract |
In this paper data were presented in an attempt to determine whether the combination of UV light and ozone would be sufficiently better than either disinfectant alone to justify implementation of both technologies for disinfection of municipal wastewater effluents. It was shown that the amount of applied ozone needed to achieve a fecal coliform limitation of 14/100 mL could be reduced as much as 80 percent if ultraviolet light either preceded or followed ozone addition. Simultaneous application of the two disinfecting agents resulted in a less than additive effect. This was apparently due to absorption of UV by ozone and subsequent reduction to molecular oxygen, since a decrease in exhaust gas ozone concentration was observed when UV and ozone were applied in the same column. From an economic perspective, combining UV light and ozone in a sequential arrangement was found to be more cost effective than either ozone or UV alone for plant sizes greater than 38,000 cu m/d (10.0 mgd). For plant sizes less than that, UV appears to be the disinfectant of choice of the two disinfectant options evaluated. |
