Membrane processes

Selection, design and optimization

Membrane processes established themselves over the years. Besides generally known applications such as seawater desalination or renal replacement, membrane processes play an increasingly important role in the process industry. They are especially attractive if a capacity increase is planned or a particularly gentle product processing is required. In pharmaceutical applications, the ultrafiltration is often a cost-effective alternative in downstream processing. Membrane contactors offer large surface areas (up to 10 000 m²/m³); electrical methods are market-leading in chlor-alkali electrolysis. The membrane distillation can make use of low-order energy. Possible membrane applications are the recovery of heterogeneous and homogeneous catalysts, the organophile nanofiltration, the increase of yields for equilibrium reactions, and – as hybrid process – the breaking of azeotropes.

In the development and optimization of membrane processes, the consideration of a variety of influence parameters is crucial for the success. In order to early evaluate the feasibility of a process we offer gradual experimental and theoretical solutions. Our experts assist you in the process design and its implementation. By accessing Siemens’ experience on laboratory, pilot and process level, you tap the membrane processes’ potential from reverse osmosis to vapor permeation to electrodialysis.
