図1は、U字型に束ねた中空糸膜2を、膜モジュールの外筒1に挿入し、外筒の端部で中空糸膜束をポッティング材3で接着・固定し、中空糸膜の開口部端面4に接して、フィルター部材5を組み入れて膜ろ過水の集水用のモジュールキャップ8を取り付けた構造をした中空糸膜型ろ過膜モジュールの例を示している。図1に示した中空糸膜型ろ過膜モジュールの使用方法の1例は、次の通りである。すなわち、濁質分を含む原水は、原水供給ノズル10Bから膜モジュールに導入され、中空糸膜の外側から内側に膜を透過してろ過される。ろ過された膜ろ過水は中空糸膜の中空部内を流れて開口部端面4から集水部7を通って膜モジュールの膜ろ過水出口ノズル6から取り出される。原水中の濁質は中空糸膜の外表面上に捕捉され堆積する。中空糸膜の外表面上に堆積した濁質のケーク層が厚くなってろ過抵抗が増大し、ろ過に要する差圧が所定の値に達したらば、原水の供給を停止して、必要に応じて、一定量のろ過水をノズル6から逆流させて逆圧洗浄し、さらにノズル11から空気を導入して空気の泡と泡の上昇に伴なって発生する水の上昇流で中空糸膜を揺動させて濁質分からなるケーク層を物理的に除去する。膜ろ過水は、中空糸膜の開口部から集水部に出た所に置かれた中空糸膜の細孔径より孔径の大きいろ過材料からなるフィルター部材5を通過して膜モジュールの透過水出口ノズル6から、膜モジュールの外部に取り出される。

In FIG. 1, hollow fiber membranes 2 bundled in a U-shape are inserted into the outer cylinder 1 of the membrane module, and the hollow fiber membrane bundle is adhered and fixed with potting material 3 at the end of the outer cylinder. An example of a hollow fiber type filtration membrane module is shown in which a filter member 5 is incorporated in contact with the opening end face 4 and a module cap 8 for collecting membrane filtration water is attached. One example of usage of the hollow fiber membrane type filtration membrane module shown in FIG. 1 is as follows. That is, raw water containing suspended solids is introduced into the membrane module from the raw water supply nozzle 10B , and permeates through the membrane from the outside to the inside of the hollow fiber membrane to be filtered. The filtered membrane filtered water flows in the hollow portion of the hollow fiber membrane, passes from the opening end face 4 through the water collecting section 7, and is taken out from the membrane filtered water outlet nozzle 6 of the membrane module. Suspended matter in the raw water is trapped and deposited on the outer surface of the hollow fiber membrane. If the suspended cake layer deposited on the outer surface of the hollow fiber membrane becomes thick and filtration resistance increases, and the differential pressure required for filtration reaches a predetermined value, the supply of raw water is stopped, and as necessary A certain amount of filtered water is reversely flowed back from the nozzle 6 and back pressure washed, air is further introduced from the nozzle 11, and the hollow fiber membrane is shaken by the rising flow of water bubbles generated as the air bubbles and bubbles rise. Move to physically remove the cake layer consisting of suspended matter. The membrane-filtered water passes through the filter member 5 made of a filtration material having a larger pore diameter than the pore diameter of the hollow fiber membrane placed at the point where it is discharged from the opening of the hollow fiber membrane to the water collection portion The nozzle 6 is taken out of the membrane module.

Suspended matter in the raw water is trapped and deposited on the outer surface of the hollow fiber membrane. If the suspended cake layer deposited on the outer surface of the hollow fiber membrane becomes thick and filtration resistance increases, and the differential pressure required for filtration reaches a predetermined value, the supply of raw water is stopped, and as necessary A certain amount of filtered water is reversely flowed back from the nozzle 17 and / or 17 'and back pressure washing, air is further introduced from the nozzle 20', and the hollow fiber membrane is swung by the rising flow of air bubbles and bubbles. Physically remove the cake layer consisting of suspended matter. In the case of a hollow fiber membrane type filtration membrane module having a structure having a plurality of raw water supply passages provided penetrating through the potting portion, pressurized air is discharged from the raw water supply passage and the foam and the foam rise. The hollow fiber membrane is rocked by the upward flow of the generated water to physically remove the cake layer consisting of the suspended matter.
