The effect of dewatering on the inactivation rates of enteric viruses in sludge was determined. For this study, water was evaporated from seeded raw sludge at 21 degrees C, and the loss of viral plaque-forming units was measured. Initial results with poliovirus showed that recoverable infectivity gradually decreased with the loss of water until the solids content reached about 65%. When the solids content was increased from 65 to 83%, a further, more dramatic decrease in virus titer of greater… CONTINUE READING
