Membrane separation device

摘要

Disclosed is a membrane separation device comprising a plurality of flat membrane elements (52) arranged in parallel to one another so as to form channels for a solution to be treated therebetween, and a collecting case (59) having a collecting space that is formed internally and communicates with filtrate flow channels of the membrane elements (52). The collecting case (59) includes a membrane element holder (53) having a plurality of slits, into which the sides of respective membrane elements (52) are inserted, and a stopper (58) which abuts on the membrane element holder (53) in the collecting case (59), and a filler (55) is provided in the slits to attach and watertightly seal between the membrane elements (52) and the membrane element holder (53).

1. A membrane separation device comprising:
a plurality of flat type membrane elements that are arranged in parallel to one another and form flow channels for a solution to be treated therebetween, the membrane elements having filtrate flow channels formed therethrough; and a collecting case having a collecting space communicating with the filtrate flow channels of the membrane elements, the collecting case comprising:
a membrane element holder having a plurality of silts, into which a respective side end of each of the membrane elements is inserted, wherein the collecting case, with an opening thereof, integrally holds the side end of each of the membrane elements; and a stopper provided in the collecting space of the collecting case, the stopper abutting on at least one of the side end of the membrane elements and the membrane element holder.
