%X A series of static adsorption experiments by activated sludge were conducted for virus removal with f2 bacteriophage, which was seeded with a high concentration as surrogates for human enteric viruses. Adsorption kinetics had shown equilibrium conditions were established in some 120 minutes and the activated sludge could get rid of more than 96% f2 bacteriophage, with 85% of total adsorption occurring in less than an hour. Freundlich isotherm model adequately described the adsorption which indicated that the removal mechanism of virus is based on a multilayer adsorption in such a heterogeneous aqueous solution system. Adsorption capacity was found to vary with pH value, metallic cation concentration and organic content in wastewater, demonstrating the importance of these parameters for the removal of virus.
