Abstract

The invention deals with the technical problem to devise a process for the extended use of electrolytes which economically ensures a high electrolyte quality without having to accept production interruptions for regeneration. Especially, it is envisaged to conduct the process for the precipitation of non-glaring metal coatings in such a manner that work can proceed in three shifts for five days per week, without encountering production interruptions due to coagulation or destruction of the fine dispersal phase, respectively, and without the additional operating cost of a heating/cooling circuit. The invention solves the problem in that during the extended use of an electrolyte a partial flow is split off which is filtered and, if applicable, regenerated by the addition of active substances and reintegrated in the operating cycle.
