Verfahren zur Aufbereitung von Entfettungsbädern

摘要

Process for preparing degreasing baths comprises separating an oil phase (38) by floating the process solution (12) in the degreasing bath (10) while heating the solution to more than 70 degrees C directly before or after flotation. Preferred Features: The temperature of the process solution is more than 85 degrees C during flotation. The oil phase floating on the surface of the process solution is cooled during flotation. The process solution is used as cooling medium for cooling the oil phase. A partial amount of the process solution is fed to a separating container (32) from the degreasing bath, prepared by flotation, and then returned to the bath.
