Abstract: In order to improve an apparatus for removing wax particles from circulating water from spray booths, comprising a system tank, to which the circulating water coming from the spray booth can be fed via an inlet, such that an efficient removal of wax particles from the circulating water is possible, it is suggested that a separation zone be provided in the system tank following the inlet, the wax particles floating up into a layer near the surface in this separation zone, and that an intake of a suction means for a floating phase comprising the layer near the surface be arranged in the system tank on a side of the separation zone opposite to the inlet.
