In the production of chemical and pharmaceutical products, separation processes play the most important role alongside the actual implementation.
Membrane technology ensures safe and economical compliance with the separation requirements of the pharmaceutical industry. From sterilization and depyrogenation of process water for fermentation, separation of enzymes and isolation of active ingredients from fermentation broths to final purification of the applicable end products.

The food industry has always appreciated the advantages of membrane technology. This technology is used with great success for the clarification of wine, vinegar and fruit juices. In addition, the dealcoholisation of beers is now carried out by dialysis using membranes. Gelatine, soft cheese, quark and whey proteins are now produced using membrane technologies. Efficient production processes for high-quality food require high-performance filters with a high quality standard and optimal economic orientation. Membrane technology has contributed significantly to this high level of technology and will always support this industry with innovative products.

Car bodies, automotive parts, household appliances or office furniture are nowadays primed by an electrophoretic coating method, the so-called e-coating. Of central importance for this technology are the paint bath care as well as the rinse water treatment by ultrafiltration. However, before these parts can be fed to the paint shop, they must be cleaned. Thus it belongs today to the state of the art in the bath care of rinsing baths to use membrane technology.

Based on the unique stability of the membrane materials with highest selectivity and functional design of the membrane elements, membrane products can be separated under extreme process conditions. In addition to the chemical industry, which processes a large number of the most aggressive process fluids, the metalworking industry is increasingly resorting to membrane processes.
Not only rinsing water, but also contaminated acids and alkalis from chemical syntheses, galvanic processes or stainless steel pickling can be clarified reliably and economically and often recycled without problems.

Water management in the paper and textile manufacturing industry has long been the job of process engineers. The membrane technology enables intelligent products for the reduction of the enormous water demand. Starting with process water purification, through numerous recyclables and water recirculation systems, e.g. press water recirculation and coating colour recycling, to waste water purification. In all process steps, membrane products for the efficient performance of these purification stages can be found today in modern factories as state-of-the-art technology.

Our lives are increasingly being accompanied by modern electronic data processing. Electronic devices surround us in almost all situations. In order to further increase the performance of these products, it is of utmost importance to install powerful processors and circuits in the smallest possible space. Membrane products are available to this industry, which are used reliably for water treatment and waste water purification for the production of printed circuit boards and chips. Only the purest water without conductivity can be used in production and this is only possible with the aid of membranes.

Membrane separation processes have proven themselves in environmental protection and are becoming increasingly popular due to their versatile and reliable applicability. Membrane technology has proven itself both in municipal and industrial wastewater treatment processes. Membrane processes are only in rare cases optimally applicable as the only process step in the solution of practical separation tasks. Rather, intelligently selected process combinations often lead to economically and technically meaningful results.

The largest market for membrane applications is seen in the international markets for water supply (excursus: chapter 8) and waste water treatment.
The reasons for this lie in the scarcity of natural drinking water resources, the increase in the world’s population and the associated increase in the use of surface water (lakes, rivers, oceans), the composition of which places high demands on purification processes due to industrial pollution. But process water in drinking water quality is also an important resource for the manufacturing industry. No clean water, no clean or pure products.
