HALTERUNG FUER EINRICHTUNGEN MIT EBENEN SEMIPERMEABLEN MEMBRANEN

摘要

Frames for clamping together the plane membranes and interposed plates of a semi-permeable membrane stack. The frame comprises two frame plates interconnected by tie-bars extending from one of the plates to pass through orifices in the other plate, the orifices being countersunk such that the tie-bars may be deformed in the orifices to limit subsequent increases in the distance between the two frame plates, so that the semi-permeable membrane stack is held tightly together.
