	abstract = {The action of ozone on poliovirus was examined employing two different methods. In the first, the filtered sewage together with a virus inoculum was added to a buffer solution which contained known concentrations of ozone. The most outstanding finding was the complete disappearance of the ozone immediately after the addition of the effluent. At the same time. there was a rapid reduction in virus titer. However. after the initial reduction, the virus titer remained unchanged. The degree of virus inactivation was dependent on ozone concentration and on the amount of organic matter in the effluent. With increased ozone concentration and decreased organic matter, a larger percentage of viruses were inactivated. With the second method, ozone was bubbled into filtered sewage containing a virus inocult, m. Inactivation of the virus started after a lag period of about 30 s. even before ozone residual in the sewage was detected. Inactivation of 99.999\% of the virus was obtained when the ozone residual was about 0.6 mg/l. In similar experiments performed with buffer instead of sewage, the entire process took place at a much faster rate. When ozone concentrations reached about 1.0 mg/l, 99.999\% of the virus was inactivated. In conclusion, ozone was found to be a very potent viral disinfectant, even in contaminated water.},
