Why do kidney dialysis patients need to take special precautions?
In the dialysis process, the compounds in water come in contact with the blood across a permeable membrane. Chloramines in that water would be harmful, just as chlorine is harmful and must be removed from water used in kidney machines. There are two ways to do that: either by adding ascorbic acid or by using a granular-activated carbon treatment. Medical centers that perform dialysis are responsible for preparing the water that enters the dialysis machines. They are informed of this change.
