The individual methods of disinfection peracetic acid (PAA) and UV radiation and combined
process PAA/UV in water (synthetic) and sanitary wastewater were employed to verify the
individual and combined action of these advanced oxidative processes on the effectiveness
of inactivation of microorganisms indicators of fecal contamination E. coli, total coliforms (in
the case of sanitary wastewater), and coliphages (such as virus indicators). Under the
experimental conditions investigated, doses of 2, 3, and 4 mg/L of PAA and contact time of …

The individual methods of disinfection peracetic acid (PAA) and UV radiation and combined process PAA/UV in water (synthetic) and sanitary wastewater were employed to verify the individual and combined action of these advanced oxidative processes on the effectiveness of inactivation of microorganisms indicators of fecal contamination E. coli, total coliforms (in the case of sanitary wastewater), and coliphages (such as virus indicators). Under the experimental conditions investigated, doses of 2, 3, and 4 mg/L of PAA and contact time of 10 minutes and 60 and 90 s exposure to UV radiation, the results indicated that the combined method PAA/UV provided superior efficacy when compared to individual methods of disinfection.
