The inactivation kinetics of ClO2 on two enteroviruses, poliovirus 1 (Mahoney) and coxsackie virus A9, and an enteric indicator of fecal pollution, Escherichia coli, were examined in laboratory studies. In addition, the disinfecting ability of ClO2 as affected by particulates (both inorganic (bentonite) and cell-associated virus preparations), and viral aggregates, was determined. ClO2 was found to be an excellent disinfectant even when compared to chlorine, especially at the pH of most drinking waters. The test viruses were found to be significantly more resistant to disinfectants than the bacterial fecal indicator organism, E. coli. Variations in disinfection rates occurred due to viral aggregation. Chlorine dioxide inactivation of cell-associated poliovirus versus unassociated poliovirus showed no protection at the turbidity levels examined. This is believed due to the cell-associated poliovirus 1 existing in a 'singles' or non-aggregation state, and that the cellular material is readily oxidized by the chlorine dioxide. Finally, a correlation exists between bentonite protection of poliovirus 1 during disinfection at increasing temperatures and increasing turbidities, i.e. as the temperature and bentonite turbidity increases, the disinfection efficiency decreases for the bentonite-adsorbed poliovirus.
