In dealcoholization, the membrane is designed so that alcohol and water can pass through the membrane, while the aromas and other ingredients of the product remain in the cycle. Various products such as beer, wine and cider can be processed with our energy-efficient membrane system.

Our gassing and degassing systems can be used to remove or enrich liquids and gases. Areas of application include fresh and waste water treatment, bioreactors and the removal of oxygen from reaction mixtures.

Extraction is a process for separating substances based on their different solubilities. Our systems are equipped with high-quality, resistant membranes that have been specially developed for use in environments with aggressive media. These membranes convince through long lifetime and flexible application for different kinds of emulsions such as of lemon oil and catalysts.

Our solutions for micro- and nanofiltration use advanced filtration technologies to separate particles and molecules in liquids. By using membranes with very small pores, proteins and other valuable ingredients can be extracted. This enables a more efficient and sustainable process.

The food and beverage industry requires separation processes in a wide variety of process stages. And because nature has set an example, membrane processes with our membranes are used there for filtration as well as for (bubble-free) gassing and degassing or for extracting specific ingredients. We use other membranes for the dealcoholization of beer, for example.

The production of food and beverages can be understood as a constant process of processing and purifying natural raw materials. Separation of unwanted components, differentiation of various ingredients, addition of additives or microbiological processes, such as in the production of alcoholic beverages, are standard operations. In addition, there is a wide range of tasks such as water treatment, water degassing or the treatment of cleaning solutions. Today, membranes are used in many of these steps. The use of our PTFE membranes makes it worthwhile to re-evaluate many of these process steps in terms of their cost-effectiveness - especially in areas where membrane processes were previously convincing in terms of quality but not economically. 

The new technology for the dealcoholization of beer is of interest to small and medium-sized breweries. With low process temperatures and maximum product protection, you can produce alcohol-free and alcohol-reduced beers with a high degree of flexibility.

In the life science industry and especially in biotechnology, membrane processes are state of the art. In addition to the classic purification and filtration of product streams, there are a large number of new applications for membranes in process and plant design.

Membrane processes offer a wide range of applications in the biotechnology, pharmaceutical and cosmetics industries. This ranges from the up-stream process through the down-stream process to the final formulation. Especially in the production of platform chemicals from renewable raw materials, membrane processes are becoming increasingly important as a key technology and offer a unique opportunity to manufacture chemical products in an eco-efficient way. An essential element in such a process chain is the successful separation of the raw materials into their individual components. The conversion to chemical raw materials takes place through a combination of suitable physical, biotechnological and chemical processes with the support of high-performance membranes in various process steps.

"All life is chemistry", and we enable more sustainable and stable processes with our membrane processes. Be it the extraction of metal salts, the recovery of catalysts or reactive extraction: all processes that can be carried out very well with PTFE membranes.

Many membranes break down again into their components when they come into contact with aggressive media and solvents. Not so PTFE. This material has long-term stability in most media and is also thermally stable at the temperatures normally used in chemical processes. This results in a multitude of interesting questions concerning the use of membranes in the chemical industry: from the separation of lower from higher molecular weight substances from the solvent (e.g. for the purpose of pre-concentration before evaporation stages to save thermal energy or for de-bottlenecking) to the chemical extraction of systems that tend to form emulsions or in metal salt extraction (recycling of used pickling agents / extraction of rare earths etc.). Numerous publications have already demonstrated the feasibility of these processes in principle; with our membranes, these ideas can now be implemented on a technical scale.
