Filed:

Oct 18, 2012

Appl. No.:

13/654918

Inventors:

Fibracast Ltd. - Ancaster, CA
Rafael SIMON - Pacific Palisades CA, US

Assignee:

FIBRACAST LTD. - Ancaster

International Classification:

B05D 3/12
B29C 53/24
B05C 11/02

US Classification:

427256, 118100, 425369, 264299, 264319

Abstract:

A piece of substrate material is formed under heat and pressure by a roller against a cavity or platen into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate is coated with a dope in a casting device having a guide portion corresponding to the shape of the substrate sheets and quenched to form a filtering membrane.

International Classification:

B01D 61/18

US Classification:

210346, 210486, 264322, 156243

Abstract:

A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.
