Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of a clearance between membrane elements even when the clearance is narrowed and to well control the generation of a cake layer on a membrane surface with the clearance narrowed by making a belt-type screen travel across the downward and upward directions of membrane element groups. SOLUTION: A belt-type screen 4 is traveling across the downward direction of membrane element groups 1,.... Since drainage introduced from the lower end opening 210 of a skirt part 21 passes through the screen 4 and ascends in a clearance 10 between the membrane elements, even when the introduced drainage contains large-sized solids, the solids can be caught by the screen 4. The screen 4 is also traveling across the upward direction of the membrane element groups 1,.... The caught solids are peeled off by ascending currents from the groups 1,... so that the clogging of the screen 4 traveling below the groups 1,... can be prevented.

Abstract: PROBLEM TO BE SOLVED: To increase the antiinner pressure strength of an adhesive layer which seals the periphery of a plain membrane by arranging the plain membrane on both faces of a framework or a support plate and reinforcing the adhesive layer around the plain membrane, with a fiber material. SOLUTION: A filtrate passage material 12 such as plastic unwoven fabric, tricot or the like is packed into a framework 11 formed by injection-molding a plastic or the like having a filtrate collection pipe part 111. In addition, a plain membrane 13 comprising an ultrafiltration membrane, a microfiltration membrane or the like, applied to the surface of a support material such as unwoven fabric, woven fabric or the like, is arranged on both faces of the framework 11. Further, an adhesive layer 14 is reinforced with a fiber material 15 in order to seal a space between the periphery of the plain membrane 13 and the framework 11. Thus it is possible to upgrade the antiinner pressure strength of the adhesive material 14 for sealing the periphery of the plain membrane 13. Consequently, the smooth circulation of an untreated liquid is securely realized between an intermembrane element gap passage and an untreated liquid space outside membrane element groups set side by side and ensure high untreated liquid treatment efficiency.
