Abstract
In a dialysis apparatus having a dialyzer and a single balance chamber, the internal volume of the balance chamber is preferably at most 2/3 of the volume of the dialysis fluid chamber within the dialyzer. As a result, during the dialysis fluid recirculation cycle, at most 2/3 of the volume of fluid within the dialysis fluid chamber will be replaced by fresh dialysis fluid. Preferably, the duration of the recirculation cycle is approximately equal to the duration of the balance chamber filling cycle.
