Abstract
A membrane separation apparatus in which a membrane clogging is moderated to lower a load to filtering. A plurality of separation membranesare stored vertical and parallel to each other inside the a casingformed with opening sections which respectively open in upper and lower directions thereby configuring a membrane module. In a flow passage through which treated water for the membrane moduleflows, a water flow guideis provided such that an opening area Sof the flow passage through which treated water outflows is smaller than an opening area Sof the flow passage through which treated water inflows. Additionally, a plurality of the membrane modulesare stacked one upon another in a direction of height of a casing thereby to configure a membrane unit. An air diffusing deviceis disposed below this membrane unitthereby configure a membrane separation apparatus
