Separation conditions of ultrafiltration membrane on PEG

Zhang Guang

Abstract

In this paper,using MWCO 6000 UF membranes,the retention experiments of PEG with different molecular weights were carried out.The removal effect of ultrafiltration membrane on different molecular weights PEG was discussed;the influences of operation conditions on the removal effect of PEG were investigated,such as filter time,operation pressure and feed concentration.The optimal conditions are obtained: operation pressure is 0.05 MP,PEG molecular weight is 20000,PEG concentration is 100 mg/L and filter time is 5 minutes.
