Abstract
Official abstract text for this publication.
A spiral wound module is suitable for use with high temperature water that is also very alkaline or has a high pH, for example SAGD produced water. The module uses a polyamide-based membrane with a polysulfone or polyethersulfone backing material. For other components, the module uses primarily one or more of, EPDM; polyamide; polyphenylene oxide; polyphenylene sulfide; polysulfone; polyethersulfone; polysulfonamide; polyvinylidene fluoride; mylar; fiberglass; and, epoxy. Polyester is not used. Polypropylene is not used for the feed spacer. For example, a module may use a PVDF feed spacer, a nylon permeate spacer and a polysulfone center tube. The center tube may be provided with 4 rows of 0.063″ diameter holes and be rolled under high tension.
First claim
Opening claim text (preview).
What is claimed is: 1. A spiral wound membrane module comprising, a membrane envelope comprising a membrane material and a permeate spacer; a feed spacer adjacent the membrane envelope; a center tube, wherein the membrane envelope and feed spacer are wrapped around the center tube; and, an anti-telescoping device attached to the center tube beside the membrane envelope and feed spacer, wherein the permeate spacer, center tube, and anti-telescoping device are each made prim…
