The use of aluminum sulfate (alum) coagulation prior to reverse osmosis (RO) treatment has been shown to be problematic. Membrane fouling was theorized to occur through soluble aluminum (AP +) reacting with ambient silica (H4SiO 2) to form kaolinite (AI2Si2Os(OH)4) within the RO unit. Chelating agen
