| Abstract: | Ethanolic extracted-liquid of Rhizoma Paridis was treated by ceramic membrane. Based on flux ofmembrane, the recovery of the steroidal saponins and effect of eliminating impurity, the separation performance of differentmembrane materials and pore sizes were investigated. The effects of parameters such as operation pressure, feed concentrationon microfiltration were shown. According to the fouling characteristics on membrane surface, the effects of different cleaningmethods were compared. The results showed that the ZrO2 membrane of 0.2mm pores size were the most satisfactory.Operation pressure, velocity of flow and backflushing method have a great influence on flux of membrane. |
| Keywords: | ceramic membrane microfiltration ethanolic extracted-liquid of Rhizoma Paridis cleaning ofmembrane |
