ABSTRACT:
Dialysis apparatus has dilution and concentration chambers arranged alternately, which chambers each are defined by ion exchange membranes and frames each disposed therebetween. Passages for introduction of air into the dilution and concentration chambers are provided at lower portions thereof. The air introduced through the passages into the dilution and concentration chambers rises upward between the ion exchange membranes and is exhausted from upper portions thereof out of the dialysis apparatus. By the introduction of the air, solutions in the dilution and concentration chambers are driven to flow upward. Condensed phosphates are added to liquid to be treated before dialysis of the liquid.
