Title: Drinking water and biofilm disinfection by fenton-like reaction
Issue Date: 2013
Abstract: A Fenton-like disinfection process was conducted with Fenton's reagent (H2O2) at pH 3 or 5on autochthonous drinking water biofilms grown on corroded or non-corroded pipe material. The biofilm disinfection by Fenton-like oxidation was limited by the low content ofiron and copper in the biomass grown on non-corroded plumbing. It was slightly improvedby spiking the distribution system with some additional iron source (soluble iron II orferrihydrite particles appeared as interesting candidates). However successful in situdisinfection of biofilms was only achieved in fully corroded cast iron pipes using H2O2 andadjusting the pH to 5. These new results provide additional support for the use of Fenton'sprocesses for cleaning drinking water distribution systems contaminated with biologicalagents or organics.
