Recycling of aqueous cleaning liquids


[Translate to Englisch:]

The R. Scheuchl GmbH has developed a worldwide new system. With this system the cleaning liquids, as used nowadays within automobile painting, can be re-processed, so that they can be used again and again.

Compared with the conventional single use and disposal of the cleaning liquids, the new system reduces the consumption of petrochemical raw materials and energy considerably. Also the emissions of CO2 and volatile organic compounds are reduced drastically.

Earlier, when solvent based paint was used within the automobile painting, volatile organic solvents were used for cleaning the paint shops. The used and paint containing solvent could be re-distilled in a simple distillation and then be re-used easily. Compared to this, the modern water-based paint systems need aqueous cleaning liquids for cleaning. These cleaning liquids contain numerous different solvents and additives. Due to chemical-physical reasons a simple distillation is not possible here.
