Abstract

The invention relates to a method for phosphating metallic surfaces. According to said method, the metallic surfaces are rinsed with rinsing water after phosphation, and the rinsing water is subjected to a two-stage or multi-stage nanofiltration process. The concentrate of a nanofiltration stage is respectively used as a parent solution for the ensuing nanofiltration stage. The concentrate of the last nanofiltration stage is used to complete the phosphation solution.
