Zusammenfassung:A membrane separation apparatus in which a membrane clogging is moderated to lower a load to filtering. A plurality of separation membranes 4 are stored vertical and parallel to each other inside the a casing 6 formed with opening sections which respectively open in upper and lower directions thereby configuring a membrane module 3. In a flow passage through which treated water for the membrane module 3 flows, a water flow guide 5 is provided such that an opening area S 2 of the flow passage through which treated water outflows is smaller than an opening area S 1 of the flow passage through which treated water inflows. Additionally, a plurality of the membrane modules 3 are stacked one upon another in a direction of height of a casing thereby to configure a membrane unit 2. An air diffusing device 7 is disposed below this membrane unit 2 thereby configure a membrane separation apparatus 1.
