Abstract

Cellulose hydrolysate ultrafiltration was investigated as in-situ separation of glucose while limiting the consumption of enzyme. Thus the high permeation of glucose through the membrane is one of the main criteria required in designing an efficient membrane reactor system. The performances of three commercial UF membranes (PES20, PA3 and PSF20) were compared in a stirred batch cell. Special attention was directed to the permeation of glucose and retention of enzyme of the cellulose hydrolysate. The effects of solution pHs and the presence of lignin on membrane fouling were evaluated. The results revealed that significant flux decline was obtained for PES20 and PSF20 membrane (44% decline), but slight flux decline occurred for PA3 membrane (13% decline). The permeation of glucose up to 90% was found to be higher for PA membrane. To mitigate fouling, it is appropriate to increase the negatively charge of the membrane surface through rising up the pH solution from the isoelectric point (IEP) of cellulose hydrolysate.
