Title (EN) HIGH FLUX MEMBRANE
(FR) MEMBRANE A FLUX ELEVE
Abstract:
(EN) A high flux ultrafiltration membrane comprises a porous substrate (for example, a polypropylene biofilter) having an ultrafiltration microskin permanently deposited thereon. The microskin is formed of a reticulated so-called Fractal membrane produced by dehydrating a calcium apatite gel or calcium aconitate gel by changing the pH. The membrane shows improved flux properties and high chemical resistance. It may be used inter alia to desalt molasses or skim milk.
(FR) Une membrane d'ultrafiltration à flux élevé comporte un substrat poreux (par exemple un biofiltre de polypropylène) sur lequel est déposée en permanence une micropellicule d'ultrafiltration. La micropellicule est formée d'une membrane réticulée appelée Fractal produite par la déshydratation d'un gel d'apatite de calcium ou d'un gel d'aconitate de calcium par modification du pH. La membrane présente des propriétés de flux améliorées et une grande résistance chimique. Elle peut être utilisée entre autres pour dessaler des molasses ou écrémer du lait.
