In an anodizing process, up to 95% of the free acid can be recovered while less than 5% of the aluminum is returned to the bath (at the appropriate volume flow ratio).
In a bases recovery process, the spiral membrane module WD achieves at least 70% recovery of the free bases.
Due to the high separation efficiency, valuable metals can also be reused at the highest value level.
- No compressed air used (energy saving)
- Less aids required (material savings)
- Less wastewater (saving wastewater costs)
The replacement of the spiral membrane module causes only a fraction of the costs compared to conventional membrane devices for bath care.
+ Extremely compact, storage containers and filter are integrated in the system.
+ Flow variation with different types of flow restrictors possible.
+ Compact, stackable design. (Picture: Two stacked modular boxes with a total of 20 spiral membrane modules.)
+ Parallel connection to a central supply unit.
