Typical salt contents in process waters compared with contents in drinking waters
Abgeschlossen-2024
Recycling of saline waters (RIKovery)

The project consortium pursued the vision of reuse industrial water flows as completely as possible in order to relieve natural water resources. The task of TZW was the development of an online process monitoring for organic trace substances in…
