Method of renewing a porous diaphragm having reduced permeability to alkali metal chloride brines |
摘要 |
A method is provided for renewing the permeability of a porous diaphragm comprised of a synthetic fluorocarbon resin having ion exchange properties which comprises feeding an alkaline solution of an alkali metal chloride having a pH of from about 9 to about 12 to the anode compartment. A first portion of the alkaline brine passes through the porous diaphragm and a second portion contacts the porous diaphragm and is then removed from the anode compartment.
