The Role of Natural Organic Matter (NOM) in the Treatment of Spent Filter Backwash Water with Membrane Technologies
(GIC-NOM)

Recycling of spent filter backwash waters (SFBW) is a sustainable way with respect to environmental protection and saving water resources. For this purpose membrane processes will be applied to remove suspended particles, organic substances and pathogens from the SFBW. However, for reliable membrane operation the fouling behavior must be studied. Therefore natural organic matter (NOM) and flocculants from SFBW and their removal efficiency by membrane processes as well as their role in membrane fouling will be characterized in lab-scale and pilot-scale experiments. For this purpose chromatographic and spectroscopic methods will be applied and fundamental water chemical parameters will be determined.
