Abstract:
A method for cleaning a hemodialysis system after completion of dialysis, comprising sequentially introducing ozone water generated by an apparatus for producing high concentration ozone water and having an average ozone concentration of not less than about 15 ppm to dialysate pipes of the hemodialysis system after completion of dialysis, said dialysate pipes including a water supply tube for guiding a dialyzing water, a water supply tube for dialysate and water drainage tube for dialysate, and then draining ozone water having an average ozone concentration of not less; than about 2 ppm from the water drainage tube,wherein the high concentration ozone water is generated directly from water by subjecting the water to a water electrolytic process using an electrolytic membrane having a positive electrode formed of a noble metal catalyst and a negative electrode formed of a noble metal catalyst disposed on opposite surfaces of the membrane.
