Description
即ち、本発明の膜分離方法は、供給液を逆浸透膜モジュールに供給して透過液と濃縮液とを得る膜分離方法において、前記供給液を膜面が監視可能な供給側分離膜に導いて膜分離を行うと共に、前記濃縮液を膜面が監視可能な濃縮側分離膜に導いて膜分離を行うことを特徴とする。
(1)前述の実施形態では、供給側膜分離手段及び濃縮側膜分離手段として、全量ろ過タイプの分離膜セルを用いる例を示したが、本発明では、図2に示すようなクロスフロータイプの分離膜セルを、供給側膜分離手段及び濃縮側膜分離手段の少なくとも一方に用いることも可能である。クロスフロータイプの分離膜セルを用いることで、膜面の目詰まりなどを防止して、長期間にわたって供給液の監視を行うことができる。
