Affinity Membrane Filtration

A-membranes is a technology-driven company offering advanced membrane separation solutions based on grafted ceramic membranes. By chemically linking selected organic moieties to the inorganic surface, we tailor membrane functionality at the molecular level to control separation performance.

This approach enables a shift from purely size-based filtration to affinity-driven separations, allowing precise tuning of membrane–solute interactions.

Our technology is particularly suited for demanding separations in organic solvents, including organic solvent nanofiltration (OSN), where conventional membranes often lack stability, and is also applicable to water-based and gas separations.

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