Abstract
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 S2 of the flow passage through which treated water outflows is smaller than an opening area S1 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.
