ENTKONSERVIERUNGSSYSTEM FOR PERMANENT FULL AUTOMATIC TREATMENT OF WASTE WATER FROM THE REMOVAL OF SURFACE PROTECTIVE COATING FACTORY NEW VEHICLES OR THE LIKE

摘要

The process treats hydrocarbon-containing solvents, pref. de-preservation agents covered by EP495348, mixed with wash water, for use in de-preservation of new vehicles, which were originally surface-protected by a preservation agent (wax). The mixt. results from high pressure steam jetting (15) or e.g. automatic hot washer systems. The original process uses a light oil separator (2), to remove solvent, the remaining water and wax mixture passing to a reaction vessel (6). Here, paraffin wax and residual hydrocarbons are flocculated as a sludge, separated by filtration. The resulting clean water is recycled for use in the wax removal washing plant.
