Reprocessing of Aqueous Rinsing Fluids
Reference project
R. Scheuchl GmbH has developed an innovative process that reprocesses the rinsing fluids of modern waterborne paints in automotive painting. As a result, these fluids can be continuously reused in closed-loop operation.
Advantages of the Process
Compared with the previous single use and disposal, the system offers considerable savings:
- Significantly reduced consumption of petrochemical raw materials
- Lower energy demand
- Drastic reduction of CO₂ emissions
- Minimisation of volatile organic compounds
Technical Background
In the past, simple distillation made it possible to reprocess solvent-based paints. However, modern water-based paint systems require aqueous rinsing fluids with complex mixtures of solvents and additives that, for chemical and physical reasons, cannot be reprocessed by standard distillation.
