Abstract: DIALYSIS LIQUID WHICH HAS PASSED THROUGH A HAEMODIALYSER, IS REGENERATED BY ADDITION OF SODIUM HYPOCHLORITE. THIS CAN DEGRADE UREA AND OTHER NITROGENOUS IMPURITIES WITHOUT PRODUCING BY-PRODUCTS INCOMPATIBLE IN A DIALYSNG LIQUID FOR USE IN HAEMODIALYSIS. A DIALYSIS LIQUID OF RELATIVELY SMALL VOLUME CAN THUS BE CIRCULATED IN CLOSED CIRCUIT THROUGH A HAEMODIALYSER.
