Abstract

A dialysis machine has a balancing system with a balancing chamber for a volumetrically exact supply and removal of dialysis solution to and from a dialyzer fluidically connected to the balancing system in operation; a water inlet system connected to the balancing system for the supply of fresh dialysis liquid, with the water inlet system having an apparatus for degassing water that is connected to an air separator of the dialysis machine, with a first subsection of the air separator serving as a mixing chamber and being connectable to at least one concentrate source via at least one concentrate line and being in fluid communication with the balancing system via at least one dialysate line, wherein the filling volume of a balancing chamber corresponds to or exceeds the sum of the volume of the mixing chamber and the inner volume of the dialysate line.
