Ion exchanges - Import export

We offer customdesigned systems for large throughputs or standard units for low ones. We work with different techniques such as softening, demineralization, complete desalination and decarbonisation. ion exchange can be used for the nitrate exchange or nitrate removal. Furthermore, humic substances can be removed reliably using an ion exchanger.

Complete desalination with ion exchangers With ion exchangers, permeate of reverse osmosis or other process waters can be completely demineralized. According to the VGB recommendations, a max. conductivity of 0,08 µS/cm is allowed for fully demineralised water.

Acid recovery out of pickling acids Salts and acids can be concentrated or separated from solutions by electrodialysis. For this, ions (anions and cations) are transported through the ion exchange membranes by the applied electrical field. Typical examples for the usage of electrodialysis are: Acid recovery at pickling lines Recovery of metals out of electro-plating rinsing water
