Abstract

Peracetic acid (PAA) is a strong oxidant/bactericide that has been applied in various industries (e.g., food processing, pharmaceuticals etc.) as a food grade disinfectant. There is increasing interest in using PAA for wastewater disinfection because it forms few disinfection byproducts and no post-treatment neutralization of the disinfectant is required. Previous studies have demonstrated good efficiency in controlling bacteria in wastewater, but limited information is available for viruses, especially ones of mammalian origin (e.g., norovirus). Therefore, a study on the infectivity reduction of murine norovirus (MNV) was undertaken to evaluate the disinfection efficacy of PAA alone and in combination with UV irradiation in treated municipal wastewater (MWW) from secondary treatment plant and phosphate buffer solution (PBS) at pH7. Experiments employing MS2 bacteriophage was also performed for comparison purposes.
