Affinity Membrane Filtration

A-membranes is a technology-driven company. We offer unique solutions in nano-, ultra- and microfiltration, based on grafted ceramic membranes. Our patented grafting technique attaches a very stable single layer of organic functional groups to the ceramic material, changing the chemical affinity of the membrane surface. By selecting the right functional groups, we tune the affinity of the membrane to your process needs and expand membrane filtration from a purely size-based operation to an affinity-based process. This way we tailor innovative and sustainable solutions for your difficult and energy consuming separations, fractionations, and purifications. Our solutions are available for both water- and solvent-based streams.

Furthermore, we offer membrane contactor based solutions such as membrane extraction, membrane distillation, dealcoholization solutions and membrane based dissolved gas management.
