Performances measured in hundredths of micrometers. Aquasource membranes have a pore diameter of about 0.01 µm. They are made of two materials: Cellulose Acetate, Hydrophilic polysulfone. The type of filtration used by Aquasource membranes is interior towards exterior. With the commissioning of its first ultrafiltration modules in 1989 (first application in the world of the process of clarification-disinfecting of drinking water by ultrafiltration in Amoncourt, in France), Aquasource has benefited from its very concrete experience with the effective qualities of its membranes.
