Abstract
Description
濾過膜で覆われた濾板の表面に、濾過膜を透過した透過液が流れる流路溝パターンが形成され、
濾板の周縁部に、流路溝パターンを流れる透過液を集めて取り出す透過液取出口が設けられた浸漬型膜分離装置を構成する膜カートリッジであって、
透過液取出口は濾板に複数設けられ、
濾板は複数の集水区域に区分けされ、
流路溝パターンは、各集水区域に形成されており、各集水区域を貫く直線状の複数の貫通流路溝を有し、
各貫通流路溝は、一端部から他端部に向って、直近の透過液取出口に漸次近付くものである。
濾板の長手方向が上下方向となるように濾板を立設した際、各透過液取出口は取付け高さの異なる位置に設けられ、
集水区域は濾板を上下複数に区分けし、
複数の集水区域のうちのいずれかの集水区域の流路溝パターンが別の集水区域の流路溝パターンと異なっているものである。
境界部分を挟んで互いに隣接する一方の集水区域内の貫通流路溝と他方の集水区域内の貫通流路溝とがヘッダー溝に連通し、
ヘッダー溝の流路断面積が貫通流路溝の流路断面積よりも大きいものである。
からより多くの透過液を集液することができる。
