Abstract The effectiveness of several conventional water treatment processes that also are or can be used as wastewater treatment processes was investigated with regard to virus removal and/or inactivation. A single virus and a standard plaque assay procedure were used. The virus was the bacteriophage f2, the Zinder strain. Phase I covered flocculation studies using several different coagulants and coagulant aids. Phase II involved batch and column studies to determine the effectiveness of activated carbon and ion exchange resins for virus removal. In Phase III waters from three sites were collected to perform variable chlorine test series and variable test time series. The variable chlorine test series indicates that free chlorine is an excellent viricide with almost immediate killing power; however, the need to maintain a combined chlorine residual was enforced as the viricidal ability of combined chlorine is much more permanent.
Highlights Notes Examines the use of flocculation, carbon and ion exchange adsorption, and chlorination for virus removal in both sewage and water treatment. Emphasis is placed on chlorination.
