The invention concerns an inorganic nanofiltration membrane with a detachment threshold between 100 and 200 daltons and comprising: a multichannel ceramic monolith support consisting of a mixture of Al2O3 and of TiO2, a microfiltration membrane separating layer, an ultrafiltration membrane separating layer, preferably consisting of ZrO2, a nanofiltration membrane separating layer, preferably consisting of ZrO2, and obtained by a sol-gel type method. This inorganic nanofiltration membrane is designed for use in the sugar industry, more particularly for tr...
1. An inorganic nanofiltration membrane comprising:a multichannel monolithic ceramic support consisting essentially of a mixture of Al2O3 and of TiO2 and exhibiting a mean equivalent pore diameter Ds of between 1 and 20 .mu.m, a microfiltration membrane separating layer situated at the surface of the channels and consisting essentially of sintered particles of metal oxide(s), whose mean equivalent pore diameter Do before sintering is between 0.1 and 3.0 .mu.m, according to a Ds/Do ratio such that 0.3
