  •  Reactivation of Fecal Coliform
    A report entitled “Examination of Reactivation and Regrowth of Fecal Coliforms in Centrifuge Dewatered Anaerobically Digested Sludges” was published in June 2006 by the Water Environment Research Foundation (WERF).  The document describes the findings of a study of fecal coliform levels in biosolids from a small sampling of treatment plants, all of which used anaerobic digestion followed with high-solids centrifugation.
