To improve the mechanical strength of a ceramic flat membrane and to stabilize water treatment.SOLUTION: A ceramic flat membrane 1 is equipped with a platy porous support 21 made of ceramic, and a filtering membrane 22 formed on an outer surface of the porous support 21. Inside the porous support 21, a plurality of water collection channels 2 in which filtered water obtained by permeating water to be treated through the filtering membrane 22 circulates is formed. Further, inside the porous support 21, an area where thickness between a membrane surface 20 of the filtering membrane 22 and the water collection channels 2 is different is ensured.SELECTED DRAWING: Figure 1
【課題】セラミック平膜の機械的強度の向上と水処理の安定化を図る。【解決手段】セラミック平膜１は、セラミックスからなる板状の多孔質支持体２１と、この多孔質支持体２１の外面に形成されるろ過膜２２とを備える。多孔質支持体２１の内部には、処理対象水がろ過膜２２を透過して得られたろ過水が流通する複数の集水チャンネル２が形成される。また、この多孔質支持体２１の内部には、ろ過膜２２の膜表面２０と集水チャンネル２との間の厚みが異なる領域が確保される。【選択図】図１
