Ion exchanges - Import export

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
