Claim:
1. A method for controlling a dialysate flow, the method comprising the steps of: perfusing a blood chamber of a dialyzer with blood and a dialysis chamber, which is separated from the blood chamber by a semi-permeable membrane, with a dialysate, controlling the dialysate flow through the dialysis chamber of the dialyzer when the value of a control factor is changed and does not lie within a limit range, caused by a continuous modulation of a property of the dialysate, whereby the control factor is a measure for the exchange of substances via the dialyzer and the controlling includes: continuously modulating the value of the property of the dialysate, determining the change of the value of the control factor caused by continuously modulating the property of the dialysate during treatment, and increasing the dialysate flow if the change of the value of the control factor exceeds the limit range, or reducing the dialysate flow if the change of the value of the control factor falls below the limit range.
