Abstract: PURPOSE: A forward osmosis membrane is provided to be efficiently used in a membrane bio-reactor tank of a sewage treatment process with high microorganism density by using non-cellulose polymer. CONSTITUTION: An osmosis membrane frame is made of porous materials. An active layer is formed on the surface of the osmosis membrane frame. A support layer is formed on the osmosis membrane frame. An auxiliary support layer is formed on the lower side of the osmosis membrane layer. The active layer, the support layer and the auxiliary support layer are made of non-cellulose polymer which is PES(Polyethersulfone) or PAN(polyacrylonitrile).
