Abstract

Using the alumina powders with different average particle sizes as main raw materials, the tubular ceramic membrane support was prepared by extrusion method, and the membrane interlayer (thickness ~20 μm) and top layer (thickness ~5 μm) were deposited on the membrane support surface by dip coating process. In order to improve the separation performance of the membrane, it was modified with FAS, nano metal oxide or graphene oxide, respectively. During the oil/water treatment, the water flux of the modified membrane is higher about 27.8–43% than that of the original membrane. The modified membrane has higher oil rejection (99%) than that of the original membrane. The results show the modification has an important role on the oil/water separation performance of the membrane.
