Decreasing photoreactivation after wastewater UV disinfection can lead to considerable savings in capital and operating costs. Objectives of this study were to determine pre- and post-UV irradiation conditions able to decrease fecal coliform photoreactivation in a wastewater effluent from the Montreal Wastewater Treatment Plant. Results of the study indicated that delaying exposure to photoreactivating light for three hours suppressed photoreactivation at UV doses of 10 and 20 mJ/cm2. At least 440 lux of visible light was needed to initiate photoreactivation, and 700 lux or greater for maximum effect. Additional experiments showed that photoreactivation was significantly decreased when visible light (400-800 nm) was simultaneously applie...
