Abstract
It is of primary importance to efficiently remove pathogenic viruses in wastewater treatment, because a large number of pathogenic viruses are excreted from patients of infectious diseases and flow into wastewater treatment plants.
However, conventional wastewater treatment processes have generally shown poor performances in virus removal
and inactivation, and the contamination of water environment with pathogenic viruses via treated wastewater has
been often reported. In this article, the characteristics of pathogenic viruses appeared in water and wastewater are
introduced, and the feasibility of the membrane bioreactor (MBR) in the removal of indigenous Noroviruses (NoVs)
from wastewater was evaluated. The results showed that indigenous NoVs were well removed by MBR, and MBR
could be the promising way to reduce viruses from wastewater and to prevent water environment from the virus contamination.
