An effluent sample from a municipal wastewater treatment plant that re
ceives a heavy loading from two textile dyeing facilities was tested f
or a variety of photoeffects. Solar irradiation of solutions containin
g the effluent produced evidence for sensitized formation of transient
oxidants, primarily singlet oxygen; dye-sensitized photooxidation of
several phenols; and photoinhibition of Escherichia coli.
