The inactivation of MS2 coliphage by sonication technology was quantified to assess the
potential for its use as an alternative disinfection treatment for drinking waters. Results
demonstrated that sonication alone inactivated the virus to non-detectable levels, especially with
long sonication times. A high power to volume ratio (900 W/L) was more effective than a low
ratio (180 W/L). Temperature was a significant factor in inactivation, as the temperature
increased to greater than 70C in less than 10 minutes at 900 W/L. Simultaneous application of
sonication and chlorination showed significant synergism. Even with short contact times, when
temperature increases were not a factor, 3.4 to 5.5 log10 inactivation was achieved by
simultaneous disinfection, compared to 3 log10 inactivation that would be predicted if the effects
were only additive. Includes 11 references, table, figures.
