Acueducto s/n Laguna de Ticoman,Mexico DF 07340,Mexico The use of iron in a +6 valence state, (Fe (VI), as FeO 224 ) was tested as a novel alternative forwastewater disinfection and decontamination. The removal of organic matter (OM) and indexmicroorganisms present in an effluent of a wastewater plant was determined using FeO 224 without any pH adjustment. It was observed that concentrations of FeO 224 ranging between 5 and14mgl 21 inactivated up to 4-log of the index microorganisms (initial concentration c.a.10
