The basis for membrane separations is the difference in permeability of a semiporous membrane to different molecular sizes. 膜分離技術(shù)的基礎是不同大小的分子對半滲透膜滲透性不同。
Ceramic membrane, a new type of membrane, may be polluted and obstructed in use, so that the flux is decreased gradually, especially for ceramic membrane used in sewage treatments. 摘要陶瓷膜是一種新型材料的膜，其在使用過(guò)程中會(huì )產(chǎn)生污染和堵塞，使膜滲透通量逐漸下降，尤其是應用于污水處理過(guò)程中的陶瓷膜，污堵隨時(shí)發(fā)生。
