Pyrolysis-GC/MS is used to evaluate the organic foulants found on two types of membranes for three natural waters. Polyamide and cellulose acetate membranes are used. Waters from Manatee Lake, Harsha Lake, and the Ohio River are used as feed waters. The pyrolysis fragments are classified into four biopolymer groups: polysaccharides, proteins, polyhydroxyaromatics, and aminosugars. The results suggest that polysaccharides preferentially associate with the cellulose acetate membrane. Both polysaccharides and proteins associate with the polyamide membrane.
