The present invention relates to a pressure supporting plate for a reverse osmosis membrane module, which is capable of improving a treatment speed of wastewater and reducing a pressure applied to a reverse osmosis membrane, the pressure supporting plate comprising: an inner ring provided at a center of the pressure supporting plate and having a drop hole through which filtered treated water is transferred; a flap formed to surround the inner ring and having a slit hole through which unfiltered concentrated water is transferred; and an outer ring formed along an edge of the flap. In this case, the flap has a thickness thinner than that of the inner ring or/and the outer ring, and a baffle for inducing transfer of the concentrated water is formed on an upper surface or/and a lower surface of the flap. 본 발명은 오폐수의 처리 속도를 향상시킬 수 있으며 역삼투막에 가해지는 압력을 감소시킬 수 있는 역삼투막 모듈용 압력지지판에 관한 것으로, 상기 압력지지판의 중앙에 마련되고 여과된 처리수가 이송되는 드롭홀이 형성된 내륜과, 상기 내륜을 감싸도록 형성되며 여과되지 않은 농축수가 이송되는 슬릿홀이 형성된 플랩과, 상기 플랩의 가장자리를 따라 형성되는 외륜으로 이루어진다. 이때, 상기 플랩은 상기 내륜 또는/및 상기 외륜보다 얇은 두께를 가지며, 상기 플랩의 상면 또는/및 하면에는 농축수의 이송을 유도하는 베플(baffle)이 형성된다.
