| Popis: | The rate of inactivation of coxsackievirus B3 during anaerobic sludge digestion was found to be 2 log units in 24 h at pH 7.0 and 35°C. The rate indicates that virus inactivating factor(s) were produced in the digestion. The virus inactivation was enhanced if the digester sludge was pasteurized at 60°C for 1 h. The reason why digesters at sewage treatment plants do not completely inactivate virus is discussed in terms of the continuous nature of digester operation. |
