Abstract
Polyethersulfone (PES) hollow fiber membranes have been widely used in many fields, such as ultrafiltration, microfiltration, reverse osmosis, liquid/liquid or liquid/solid separation, gas separation, hemodialysis, and so on. In this paper, the sheet PES hollow fiber membranes were prepared and post-processing of membranes were studied. Suction method and pressing hot water method can both increase pure water flux of membrane. Suction method is more efficient and with a smaller time to increase pure water flux. After membrane was soaked into glycerol/water solution, pure water flux of membrane increased greatly and the length shrinkage ratio of the membrane was more smaller.
