AWWA ACE99472

The biofilm formation potential was measured in several raw and treated waters in Norway. In some of these waters the molecular weight distribution of the dissolved organic carbon was measured as well. All the treatment processes for removal of natural organic matter investigated, coagulation/separation, membrane filtration and ion exchange, reduce the biofilm formation potential measured as biodegradable organic carbon considerably. Coagulation/separation and ion exchange reduce the biofilm formation potential measured as assimilable organic carbon. Membrane filtration gave only a minor reduction in the amount of assimilable organic carbon. Coagulation/separation reduces the dissolved organic carbon in all molecular weight fractions. Chlorination increases the assimilable organic carbon but not the biodegradable organic carbon.
