Project “RE-Salt” – Recycling of industrial process brines

This project deals with the recovery of the salt (NaCl) contained in industrial wastewater streams and its recycling as a raw material into chlorine-alkali electrolysis as well as the further processing of the resulting water. The project comprises the following steps:

Development of trace substance analytical methods for highly saline solutions
Purification of brines by appropriate adsorptive and electrochemical processes
Concentration of the saline solutions by means of innovative and environmentally friendly processes (e.g. using waste heat at a low energy level)
Evaluation of utilization possibilities of the purified and concentrated wastewater streams obtained in chlor-alkali electrolysis
