Description
また、図２に示すように、エレメント配列固定具を平膜エレメント３の上部に配置する他に、平膜エレメント３の下部に接触させて下部弾性部材８を配置し、平膜エレメント３を上下対応する位置で挟み込むように固定することが、平膜エレメントの振動をさらに吸収・抑制させるために好ましい。この下部弾性部材８は、前記した配列固定具の弾性部材２と同様、弾性を有する材質であれば、素材は特に限定されないが、エチレン−プロピレン−ジエンゴム（ＥＰＤＭ）、スチレン−ブタジエンゴム（ＳＢＲ）、ブタジエンゴム（ＢＲ）、アクリルニトリル−ブタジエンゴム（ＮＢＲ）などが好ましく利用できる。また、下部弾性部材８の形状としては平板状でも良いが、櫛歯状として、配列された平膜エレメントの下端部のエレメント間に歯部を挿入させて装着させてもよい。
Further, as shown in FIG. 2, in addition to arranging the element arrangement fixture on the upper part of the flat membrane element 3, the lower elastic member 8 is arranged in contact with the lower part of the flat membrane element 3, and the flat membrane element 3 is Fixing so as to be sandwiched at corresponding positions is preferable in order to further absorb and suppress vibration of the flat membrane element. The lower elastic-member 8, similarly to the elastic member 2 of the sequences fixture, as long as the material has elasticity, but the material is not particularly limited, ethylene - propylene - diene rubber (EPDM), styrene - butadiene rubber (SBR ), Butadiene rubber (BR), acrylonitrile-butadiene rubber (NBR) and the like can be preferably used. The shape of the lower elastic member 8 may be a flat plate shape, or may be a comb tooth shape with a tooth portion inserted between the elements at the lower end of the arranged flat membrane elements.
また、配列させた平膜エレメント３の鉛直下方には膜面洗浄用の散気管１０を設置した。該散気管１０は、筒状の支持部材の外周に、ＥＰＤＭゴム製の微細スリットが入ったゴムシート材を設置し、前記支持部材外周と前記微細スリットゴムシート材との間隙にエアを供給することにより、清水時平均径２ｍｍの気泡を発生させるものである。
Also, vertically below the flat membrane element bets 3 are arranged to set up the diffusing pipe 10 of membrane surface cleaning. The diffuser pipe 10 is provided with a rubber sheet material having fine slits made of EPDM rubber on the outer periphery of a cylindrical support member, and supplies air to the gap between the outer periphery of the support member and the fine slit rubber sheet material. Thus, bubbles with an average diameter of 2 mm are generated during clean water.
