Permeate carrier fabric for membrane filters

摘要

A permeate carrier fabric includes at least some monofilament synthetic yarns to provide adequate stiffness and reduce blockage of permeate flow.

主权项

1. A permeate carrier fabric for placement between adjacent filter membranes of reverse osmosis, nanofiltration, ultrafiltration, or microfiltration systems, comprising:
a) at least some monofilament synthetic yarn ends selected from the group consisting of polyester and nylon, b) the monofilament synthetic yarn being between 10 and 40 denier, c) whereby the permeate carrier fabric is a tricot knit fabric formed of the monofilament synthetic yarn, the tricot knit fabric having raised rows of stitches that form continuous channels along a face of the fabric for flow of fluid being filtered by the adjacent filter membranes; and d) whereby the permeate carrier fabric is configured to support adjacent filter membranes while reducing the blockage of permeate flow.
