| [ Summary ] |
Dialysate purification has been a major focus of dialysis treatment. Revision of control standards for dialysates is discussed. Dialysate purification depends on dilution water to prepare the dialysate. Various measures are being implimented for dialysate management. Problems lie in the process after the dialysate passes the activated carbon filter, due to the structure of water treatment systems. These problems include increases in bacteria and endotoxins (ET) after chloride removal, damaged RO membranes due to incomplete chloride removal, resulting in reduced water quality. In relation to anti-bacterial measures some manufacturers build sterilization units employing chemical solutions or hot water into the downstream process past the RO module. |
