Title (EN) MONOPERSULFATE TREATMENT OF MEMBRANES
(FR) TRAITEMENT DE MEMBRANES AVEC UN MONOPERSULFATE
Abstract:
(EN) A method of improving the water permeability and/or cleaning a porous polymeric microfiltration or ultrafiltration membrane, preferably a hydrophobic/hydrophilic blended membrane, eg P VdF/PVP comprising the step of contacting the porous polymeric membrane with a source of monopersulfate, preferably an aqueous solution of 2KHSO5.KHSO4.K2SO4.
(FR) La présente invention concerne un procédé destiné à améliorer la perméabilité à l'eau et/ou à nettoyer une membrane polymère poreuse de microfiltration ou d'ultrafiltration, de préférence une membrane mélangée hydrophobe/hydrophile, par exemple le PVDF/la PVP comprenant l’étape consistant à mettre en contact la membrane polymère poreuse avec une source de monopersulfate, de préférence une solution aqueuse de 2 KHSO5.KHSO4.K2SO4.
