A quaternary ammonium-type anion exchange resin was tested as a contact water viral disinfectant. Suspensions of tapwater containing approx. 104 plaque-forming units ml-1 of poliovirus type 1 and Simian rotavirus SA-11 were passed through 1 ml beds of resin, at flow rates of 10-12 ml min-1. With resin 14-1.91 - > 99.9% of the input virus was removed. The beds were effective in removal of virus even after passage of 1500 ml of tapwater. Less than 10% of the virus associated with resin 14-1 could be recovered as compared to 100% for control resin. Kinetic studies indicated that virus adsorbed to the resins were being inactivated.
