Abstract
(EN)
Filtration membranes comprising a microporous sheet of polyolefin grafted with a poloxamer are described. In an embodiment, the poloxamer is that supplied under the trade name PLURONIC™ P-123 and the polyolefin is poly(ethylene). The membranes provide the advantage of being tolerant to the cleaning agents used in clean-in-place protocols and can be used to remove particulates from these aqueous feed streams.
(FR)
L'invention concerne des membranes de filtration comprenant une feuille microporeuse de polyoléfine greffée avec un poloxamère. Dans un mode de réalisation, le poloxamère est celui fourni sous la dénomination commerciale PLURONIC™ P-123 et la polyoléfine est le poly(éthylène). Les membranes présentent l'avantage d'être tolérantes aux agents de nettoyage utilisés dans des protocoles de nettoyage en place et peuvent être utilisées pour éliminer les particules de ces courants d'alimentation aqueux.
