Separator for separating solids from a wastewater mixture, in particular a dental wastewater mixture, comprising a housing having a cover and a centrifuge drum rotatably mounted in a centrifuge chamber of the housing and rotationally drivable, wherein: - the housing has a mixture inlet opening into the centrifuge chamber for the wastewater mixture to be separated and a liquid outlet for liquid separated from the wastewater mixture, - an overflow opening is formed between the upper side of the centrifuge drum and the housing such that liquid from the centrifuge drum can move from the centrifuge drum into an outlet chamber connected to the liquid outlet during the centrifuging process, - the housing has an air outlet that opens into the centrifuge chamber, through which air can be sucked from the region of the mixture inlet, the centrifuge drum, and/or the overflow opening, - a mixture distributor is rotatably supported within the centrifuge drum and is rotationally drivable, and - the mixture distributor is configured to distribute the wastewater mixture exiting the mixture inlet in the centrifuge drum and/or to hurl it toward its inner wall, characterized in that - the mixture distributor comprises at least one continuous air channel and is arranged in the region of the opening of the air outlet such that the air sucked in from the centrifuge drum flows through the at least one air channel into the air outlet, and - the centrifuge drum is configured such that after a centrifuging process, solids sinking under the effect of gravity remain in the centrifuge drum, with the centrifuge drum being able to be exposed by opening the cover and being removable from the housing with the collected solids remaining therein. - the housing has a mixture inlet opening into the centrifuge chamber for the wastewater mixture to be separated and a liquid outlet for liquid separated from the wastewater mixture, - an overflow opening is formed between the upper side of the centrifuge drum and the housing such that liquid from the centrifuge drum can move from the centrifuge drum into an outlet chamber connected to the liquid outlet during the centrifuging process, - the housing has an air outlet that opens into the centrifuge chamber, through which air can be sucked from the region of the mixture inlet, the centrifuge drum, and/or the overflow opening, - a mixture distributor is rotatably supported within the centrifuge drum and is rotationally drivable, and - the mixture distributor is configured to distribute the wastewater mixture exiting the mixture inlet in the centrifuge drum and/or to hurl it toward its inner wall, - the mixture distributor comprises at least one continuous air channel and is arranged in the region of the opening of the air outlet such that the air sucked in from the centrifuge drum flows through the at least one air channel into the air outlet, and - the centrifuge drum is configured such that after a centrifuging process, solids sinking under the effect of gravity remain in the centrifuge drum, with the centrifuge drum being able to be exposed by opening the cover and being removable from the housing with the collected solids remaining therein.
