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