Abstract/Contents

Abstract: Virus-removal capability of the POWER* system is compared against that of an existing wastewater treatment system (WWTS). The POWER system resulted in 99.9% reduction of somatic coliphages and 94.2% reduction of F-specific coliphages within three days of fed-batch processing. Even though the existing WWTS effectively removed somatic coliphages, the chlorinated effluent still contains 305 PFU/mL F-specific coliphages. While the chlorinated effluent of the existing WWTS still accommodated Enterovirus and Norovirus GI, the POWER system achieved more than 80% reduction of Enterovirus and 96% reduction of Norovirus GI prior to a tertiary disinfection step. Other pathogenic viruses such as Adenovirus, BK Polyomavirus, JC polyomavirus, and Norovirus GII were not detected in the effluent of the POWER system. Virus community profile in the existing WWTS was highly diverse with more than 151 virus species in the chlorinated effluent. Thirteen different pathogenic virus genera were detected in the existing WWTS effluent while only three genera were detected in the effluent of the POWER system.
