Abstract

L'invention concerne un ensemble filtre comprenant une enceinte haute pression renfermant un filtre, éventuellement fibreux, reposant sur des supports et des éléments terminaux. Cet ensemble fait office de préfiltre pour les fluides hautes pressions (notamment pour les pressions supérieures à 200 kPa). L'ensemble filtre peut être utilisé comme préfiltre pour un filtre d'osmose inverse, notamment dans un système de dessalement de l'eau de mer ou autre fluide contenant du sel.
