Abstract
A microporous ceramic membrane comprises a porous support and a microporous layer firmly bound to each other, with a sharp geometric transition between the support and the microporous layer, the microporous layer being free of pin-holes. The microporous membrane has a predetermined average pore diameter and it is suitable for microfiltration. The membrane can comprise further microporous layers making it suitable for ultrafiltration and hyperfiltration. The membrane can be prepared by suspension coating of a support, whereby the support and/or the suspension are pretreated in order to lower temporarily the affinity between the support and the suspension.
