The persistency and survival of pathogenic contamination related to biological risk has been a public concern when implementing
water reclamation and reuse. To secure the public health risk when implementing water reuse, adequate treatment is needed.
In this study Ultraviolet (UV), based treatment was studied for the applicability to remove microorganisms from secondary
effluent. E.coli, Qβ, T4 and Lambda phages were used as targeted microorganisms during the UV treatment process. The
objectives of this study were to investigate the inactivation characteristics of E.coli, Qβ, T4 and Lambda phage to UV treatment
process and investigate the effect of combine UV/H2O2 for E.coli and Qβ phage inactivation. As a result, T4 and Lambda phage
from DNA group phage were found more resistant to UV treatment process compared to Qβ phage from FRNA phage group
and E.coli from coliform group. Combined process UV/H2O2 in secondary effluent could increase the inactivation efficiency of
E.coli and Qβ. DOC and UV 254 were found strongly affected the disinfection processes. Secondary effluent treated with UV
processes was found suitable for wastewater reclamations
