Title (EN) USE OF EXTENDED SURFACTANTS IN PROCESS MEMBRANE CLEANING
(FR) UTILISATION DE TENSIOACTIFS ÉTENDUS DANS LE NETTOYAGE D'UNE MEMBRANE DE TRAITEMENT
Abstract:
(EN) Disclosed are membrane separation cleaning processes and clean in place compositions for such membranes. The cleaning compositions can remove proteins, fats, and other food, beverage, and brewery based soils and offer an environmentally friendly alternative surfactant system to NPE. Branched extended chain PO/EO nonionic surfactants with certain characteristics may be used to provide superior cleaning to membranes. The specific surfactants may be used alone or in combination. In some embodiments, the surfactant package is used as part of a cleaning composition.
(FR) L'invention concerne des processus de nettoyage par séparation par membrane et des compositions de nettoyage en place pour de telles membranes. Les compositions de nettoyage peuvent enlever les protéines, les matières grasses, et d'autres salissures à base d'aliments, de boisson, et de produits de brasserie et offrent un système tensioactif alternatif écologique au NPE. Des tensioactifs non ioniques de PO/EO à chaîne étendue ramifiée ayant certaines caractéristiques peuvent être utilisés pour fournir un nettoyage supérieur aux membranes. Les tensioactifs spécifiques peuvent être utilisés seuls ou combinés. Dans certains modes de réalisation, le conditionnement de tensioactif est utilisé en tant que partie d'une composition de nettoyage.
