| Abstract |
In this investigation four wastewater treatment plants were studied and compared in their ability to inactivate naturally occurring enteroviruses. Of the four plants tested, two used chlorine as the disinfectant, one used ozone, and one used ultraviolet light. Results of field testing are summarized as follows. Both virus titers and isolation rates (percentage of samples positive for virus) were low in the undisinfected effluents. As a result there was no consistent correlation between virus numbers and any of the traditionally measured bacteriological indicators. Also, no seasonal variation in virus titers was detected in any of the effluents. However, a diurnal variation was observed in one of the plants during two separate samplings. Virus titers and isolation rates in the disinfected effluents were significantly lower than in the undisinfected controls. However, the numbers were too low to detect differences between plants or disinfectants. At least 10 different virus types were isolated in the tested effluents. The predominant virus type was poliovirus 1. Seeding experiments with attenuated strains of poliovirus were performed to evaluate the recovery efficiency in each effluent. Efficiencies were low and markedly variable. |
