The Effect of Temperature on the Destruction of Salmonellas in Activated Sludge

The effect of temperature on the survival of salmonellas in activated sludge was examined. The results showed that the Salmonella destruction rates increased in line with increasing temperature of the mixed liquor from 5° to 25°C, whereas at 30°C the rate declined markedly. This is most probably due...
