【Abstract】 In this paper, the effect of reclamation of Lyocell Cellulose Solution by ZrO2 ceramic dynamic membrane was investigated through studying the influences of the operating parameters, such as filtration pressure, crossflow velocity on membrane flux. The optimized operating conditions were advanced. Aiming at the membrane fouling appeared in reclamation process, a physical method was utilized to wash the membrane.更多还原
