Inactivation of f2 coliphage in municipal effluent by the use of various disinfectants

Abstract

Bromine chloride, chlorine and peracetic acid inactivated f2 coliphage in effluent but in order to achieve 99·99% inactivation the three disinfectants were required at about 1, 10 and 100 mg/l respectively. The activity of chlorine was halved by the presence of added organic matter, whereas bromine chloride and peracetic acid were very little affected. When a second successive dose of virus was added to the reaction mixture, the virus was inactivated only by peracetic acid despite the fact that in the chlorine-treated effluent residual chlorine was detected. The addition of a second dose of disinfectant inactivated residual virus in the same way as the first dose. © 1980, Cambridge University Press. All rights reserved.
