Title (EN) METHOD FOR CLEANING AND A VEHICLE CLEANING SYSTEM
(FR) PROCEDE DE NETTOYAGE ET SYSTEME DE NETTOYAGE DE VEHICULE
Abstract:
(EN) Process and plant for washing without waste water discharges. The washing is done with recycling wash water, which is continuously purified and regenerated between each use. The rinsing is done in at least two stages. The wash water and the rinse water are recycled in two separate circuits balanced against each other in such a way that the water additions to the system may be limited to correspond to the losses through withdraw. In this way the plant can operate without generating surplus of wash water that must be discharged to the sewage system.
(FR) La présente invention concerne un procédé et une station de lavage permettant un lavage sans évacuation des eaux usées. Le lavage est réalisé avec de l'eau de lavage recyclée qui est continuellement purifiée et régénérée entre chaque utilisation. Le rinçage s'effectue en au moins deux étapes. L'eau de lavage et l'eau de rinçage sont recyclées dans deux circuits séparés en équilibre l'un par rapport à l'autre de sorte que les adjonctions d'eau au système peuvent être limitées pour correspondre aux pertes par prélèvement d'eau. De cette manière, la station peut fonctionner sans produire un surplus d'eau devant être évacué dans un système d'évacuation des eaux usées.
