The ability of ultraviolet (UV) light to disinfect alum floc-associated MS-2 coliphagewas evaluated. Bench experiments were conducted in which MS-2, a viral surrogate, waseither coagulated with kaolin clay particles or aggregated into viral clumps prior to UVexposure. The bench experiments were designed to represent particle sizes, viralaggregates, and turbidities encountered in drinking water treatment. A third condition,consisting of MS-2 in clear, phosphate buffer solution served as a control forcomparison. The results suggest that enmeshment within floc particles and aggregationinto viral clumps protect viruses from UV disinfection. Up to a 1.1-log reduction in MS-2inactivation was observed due to these factors. Viral enmeshment and aggregation wereconfirmed using transmission electron microscopy. Includes 14 references, tables, figures.
