摘要

Process for cleaning a process bath, especially for cleaning a Zn/Ni-electrolyte bath for a galvanic process, comprises evaporating a part of the process bath used in the process until phase separation into a lower phase, a middle phase and an upper phase occurs, and removing the upper and lower phases. An independent claim is also included for a device for cleaning a process bath, especially for cleaning a Zn/Ni-electrolyte of a galvanic process, comprising a unit (2) for evaporating the process bath and/or rinsing water after the process bath, and a unit (4) for removing the phases of the process bath and/or the rinsing bath.
