Fouling characteristics and autopsy of a PES ultrafiltration membrane in cyclodextrins separation

This paper studies the fouling characteristics and effect of chemical cleaning (alkaline and acidic solution) on PES ultrafiltration membrane during separation of cyclodextrins from starch and CGTase. The fouled membrane surface was observed under scanning electron microscopy (SEM). The ATR/FTIR sp...
