A method and a device for ultrafiltration during hemodialysis are described in which ultrafiltrate fluid, before removal from the dialysis circuit, is passed through a balancing device, which is also used as ultrafiltrate pump. For this purpose, a controller controls and actuates inlet, outlet, and dialyzer valves, in such a way that a desired amount of ultrafiltrate, corresponding to the filling volume of a balancing chamber or a multiple thereof, is introduced to the discharge through the balancing chamber. In order to carry out continuous ultrafiltration during hemodialysis, a predetermined amount of air is introduced to the dialysis fluid flow circuit through an air separator and is then pumped off during hemodialysis so that a corresponding amount of ultrafiltrate is obtained.
