Anisotropic Ceramic Membranes from self-organized nanoporous alumina (also known as Anodic Aluminum Oxide or AAO) contain two layers with different pore structure integrated into a monolithic membrane:

Support Layer –  spans most of the membrane thickness and contains large uniform pores with porosity of up to 50% to provide mechanical strength and high  permeance.

Active Layer – a thin layer of AAO with highly uniform pores to enable highly selective size-based (2 to 100 nm) separation with very sharp molecular weight cutoff, suitable for nano- and ultrafiltration applications.
