Title:
REVERSE OSMOSIS FILTER MODULE
Document Type and Number:
WIPO Patent Application WO/2017/057833
Kind Code:
A1
Abstract:
The present invention relates to a reverse osmosis filter module including an improved feed spacer, and to a reverse osmosis filter module including an improved feed spacer, the module having an asymmetric diameter in an endpoint area in which a first set and a second set of filaments are crossed, so as to develop a turbulent flow while lowering differential pressure, by increasing a cross sectional area of a flow path, thereby enabling concentration polarization to be mitigated.
