ABSTRACT:
Foraminous plates formed from coiled or parallel tape lengths may be inserted between the tubesheet and a ported casing-end in a hollow-fiber type permeator, to convey effluent from the fiber lumens to the port and to support the tubesheet against the pressure differential between its inner and outer faces. The face of the support plate which the tubesheet will bear against is defined by edges of the tapes, which are held radially or laterally apart by spacing means adapted to permit effluent flow through the plate between the tapes. Either the casing-end or the plate surface bearing against it is grooved.
