ABSTRACT:
A filter element, for use in a plate filter press for example, includes a membrane supported from a plate and captured, about the periphery of an opening in the plate, by a clamping ring which locates a shaped edge bead on the membrane in a complementary shaped groove in the plate. The clamping ring has a bearing surface, which contacts a surface of the membrane edge bead which is oppositely disposed with respect to the portion thereof which cooperates with the groove in the plate, having an angle of inclination with respect to the plane of the plate which directs forces produced by pressure induced expansion of the membrane to the clamping ring in a generally radial direction with respect to the axis of the opening in the plate.
