Inactivation of indigenous (total coliforms, aerobic spores) and spiked (MS-2 coliphage)
microorganisms in reuse water from several wastewater treatment facilities across North
America is being studied. By evaluating a variety of current and emerging treatment
technologies, including ultraviolet (UV), O3, peracetic acid (PAA), and advanced oxidation processes (e.g. UV-H2O2,
UV-PAA etc.), a comparative understanding of each technology will be developed.
Initial results show rapid inactivation of indigenous coliforms by UV-based technologies,
and log-linear inactivation of indigenous spores and spiked MS-2 virus. Addition of
H2O2 to the sample prior to irradiation slightly improves coliform inactivation but has no
impact on aerobic spores or MS-2. Ozonation is highly effective against coliform and
MS-2, but largely ineffective against aerobic spores. Includes 24 references, table, figures.
