In nature, most of the organic and inorganic substances which are used as starting materials for products are mixtures of substances. Chemical synthesis also usually produces mixtures of substances or products that are contaminated with by-products. A key task in most processes in chemistry and biotechnology is therefore the separation of molecules from mixtures, either to obtain or purify substances or to remove interfering by-products.
Fraunhofer IGB has established a wide range of different separation processes and has the corresponding apparatus and equipment available both on a laboratory and pilot scale. Membrane and adsorption processes, electrophysical and thermal processes, but also crystallization, extraction and chromatography processes are constantly being further developed and optimized for various applications within the scope of our own research work.
A unique selling proposition of our institute is the possibility to combine these processes flexibly – if necessary with other classical processes such as centrifugation or flotation – and to integrate them into process chains. This know-how can also be used for water treatment, recycling or in food processing technology.
A large number of the separation processes presented here is used for the purification of products from biotechnological processes.
