ABSTRACT:
A frame and membrane assembly for a cell subject to fluid flow. The frame includes a peripheral portion having opposite faces which are to be sealed together. One of the faces is planar while the other of the faces is provided with a plurality of grooves. In an outermost groove there is a final sealing ring. An intermediate groove is generally dovetail shaped in cross section and the peripheral portion of a membrane is locked within that groove by a second sealing ring which deforms under pressure to increase the mechanical interlock while further forming an intermediate seal between two adjacent frames. A principal feature is an innermost groove in which there is seated a third sealing ring. The third sealing ring underlies the membrane and when two adjacent frames are brought together in the formation of a cell, the membrane is forced against the underlying sealing ring which deforms and resiliently clamps the membrane against the next adajcent frame so as to form an innermost seal.
