The invention relates to an apparatus and to a method for supplying dialysate. The invention also relates to a dialysis apparatus comprising an apparatus for supplying dialysate. The apparatus for supplying dialysate has a balancing device, which comprises at least one balancing chamberfor balancing fresh and used dialysate, and a metering devicefor filling the at least one balancing chamber with permeate and concentrates in a specified mixing ratio for producing dialysate. The metering deviceis designed such that specified volumes of concentrates are conveyed into the at least one balancing chamberin successive working cycles. Given that the specified volumes of concentrates are not added simultaneously, the concentrates can be conveyed using just one single metering pump. This is advantageous in that the metering pump is a relatively expensive component of the mixer circuit. In practice, the design is simpler and compact and the maintenance costs are reduced.
