FILTRATION MEMBRANE, MEMBRANE MODULE, AND WATER TREATMENT DEVICE

摘要

A filtration membrane (10) comprises a membrane body (1) having multiple pores (3) for filtering raw water, and a particle layer (6) for removal of impurities contained in raw water that adhere to and accumulate on a surface (8) of the membrane body (1). Moreover, membrane modules (20) and (40) optionally comprise a vessel (18) having an intake port (12) and a discharge port (13), and the filtration membrane (10) housed inside the vessel (18) as a single unit therewith. In addition, water treatment devices (100) and (100A) optionally comprise the membrane modules (20) and (40) and have a configuration whereby raw water is introduced to the membrane modules (20) and (40) and purified to obtain purified water.
