The invention relates to a separator for separating solids from a water mixture, the separator comprising: a housing having a lid; and a centrifuge basket which is rotatably mounted in a centrifuge chamber of the housing and can be driven in rotation. The housing has a mixture inlet for the waste water mixture to be separated, which inlet opens into the centrifuge chamber, and a liquid outlet for liquid separated from the waste water mixture. An overflow opening is formed between the upper side of the centrifuge basket and the housing such that, during the centrifugal process, liquid can flow from the centrifuge basket into an outlet chamber which is connected to the liquid outlet. According to the invention, the centrifuge basket is designed such that, after the centrifugal process, solids which sink under the effect of gravity remain in the centrifuge basket.
