FUMATECH BWT - The company's functional membrane and systems engineering - is a leading manufacturer of ion exchange membranes for a variety of electrochemical processes. Our advanced coatings produce porous, non-porous and functional films with excellent acid, alkali, solvent and oxidative properties. With the clean room, we further improve polymer production and high-tech air purification, which will meet our future requirements for our new membrane coating system, our water treatment technology, innovative energy conversion and energy storage batteries using fuel cells Another important step in the new market. The Fumex membrane is manufactured using FUMATECH's proprietary solution mapping technology. They are available in standard sizes, for example, 200 x 300 mm, 520 x 520 mm, 520 x 1050 mm and are available in other sizes upon request. With a maximum width of 1650 mm, it can produce rolls from 10μm to 500μm thick.
Types fumasep FAS and fumasep FKS are homogeneous standard anion and cation exchange membranes for electrodialysis and reverse electrodialysis. These are low cost membrane types with and without reinforcement. Depending on the application, these types of films are optimized for thickness, conductivity, selectivity and sheet resistance. Recommended applications include, for example, desalination processes, salts, acid and base concentrations, and the removal of nitrogen compounds from drinking water.
Membrane for bipolar membrane electrodialysis
Our products fumasep FAB, FKB and FBM are designed and optimized for bipolar membrane electrodialysis. The EDBM is a combination of conventional electrodialysis for separation of electrochemical water into a salt and conversion to the corresponding acid and base salts. Fumasep FAB is an anion exchange membrane with the ability to block protons to obtain high concentrations of acid. The high cation transport optimized cation exchange membrane of fumasep FKB and OH Ionen.fumasep FBM is a bipolar membrane that induces water cleavage into protons and hydroxide ions. The Fumex FBM bipolar membrane combines high selectivity and high efficiency with high chemical stability over a wide pH range, very good mechanical stability and low electrical resistance. It is ideal for the production of acids and bases from the corresponding salts, as well as innovative concepts such as biofuel cells. The patented multilayer film consists of a selective anion and a cation exchange layer. The decomposition of water into protons and hydroxide ions takes place in a special intermediate layer. Water is transferred to the layer by osmosis. The decomposition of water into protons and hydroxide ions takes place in a special intermediate layer. Water is transferred to the layer by osmosis.

Special film type
The Fumasep FAD anion exchange membrane is a membrane type with excellent proton and anion transport properties and high metal ion retention efficiency. These properties are necessary for operation in a diffusion dialysis system for the production of free acid from spent process bath solutions, such as from surface finishing or from textile processing. Depending on the process, it can be recovered and in this way 95% of the free acid and up to 80% of the liquid are recovered in the production process, thus saving additional treatment bath or wastewater treatment können.fumasepFAP is required for chlorine-resistant anion exchange membranes Also chemicals, which also allow for the transport of protons. The film is suitable for a variety of applications.
The fluorinated membrane Fomappi F grade is a perfluorosulfonic acid/PTFE-based cation exchange membrane with excellent chemical stability and excellent ionic conductivity for electrolysis. Films were produced with and without reinforcement to achieve high mechanical and chemical stability. A further application is the production of sodium hypochlorite and hypochlorous acid for water disinfection.
