Abstract
Peracetic acid (PAA) has broad application in disinfection, since it produces fewer disinfection by-products. In this study, PAA was used as a disinfectant to inactivate Escherichia coli, Staphylococcus aureus, and Bacillus subtilis under different pHs and turbidity. The effects of different environmental factors on PAA disinfection were compared. The results were fitted by the common disinfection kinetic models, and the CTs were finally calculated according to the disinfectant decay models and the optimal disinfection kinetic models. By comparing PAA with other common disinfectants, the projected application of PAA was discussed.
