✦ Synopsis

In the process of desalination by reverse osmosis, raw sea water is usually pretreated to keep membrane perfomance. For example, to prevent fouling of membrane, removing of suspended solid is usually recommended. In this study, to simplify removing process of suspended solid, first stage membrane performance in two stige system was sutdied by using NRO tubular module end three types of membrane. One of these membranes was made from cellulose diacetate and others were blended membranes of di-and trf -acetate. And also these data were compcred with similar ones taken with NaC1 solution.
