Abstract

In order to separate solids from a solid material-liquid mixture that is collected in a dental treatment centre, a housing (1) has a sedimentation container (13) in which two sedimentation zones (22, 36) are arranged one above the other. Both the mixture inlet (4) and the liquid outlet (24) are arranged above a predetermined sedimentation level, the liquid outlet channel (24) being provided in the form of a free overflow into a drain tube (25).
