Title:
PRETREATMENT OF DIAPHRAGMS USED IN ELECTROCHEMICAL PROCESSES
Document Type and Number:
WIPO Patent Application WO/2018/136337
Kind Code:
A3
Abstract:
Devices and methods for electrode diaphragms are presented in which a hydrophobic polymeric diaphragm is pretreated with ions present in an electrolyte under conditions that are effective to increase wettability of the diaphragm. It is contemplated that the diaphragm can first be exposed to a wetting agent and then placed in an aqueous electrolyte used in an electrochemical process. Current can be applied in an amount sufficient to drive ions of the ionic solution into the polymeric diaphragm.
