 Membranes can be described as semipermeable barriers. Out of a mixture of multiple substances, certain components are allowed to pass this barrier while others are retained by the membrane. The intention of the research work at Membrana is to develop sophisticated membranes and offer tailor-made solutions for diverse separation problems.

Membrana holds extensive knowledge in the development of membranes with various polymer/solvent/nonsolvent systems. The development is mainly based on two fundamental methods: solvent induced phase separation (SIPS) and thermally induced phase separation (TIPS). The variation of the membrane morphology and pore structure is possible by control of thermodynamics (concentration, composition) and kinetics (temperature, residence time, drawing-relaxation).

These technologies provide the possibilities to form capillary and flat membranes from a wide variety of polymers covering the whole ultra- and microfiltration range.
