Microbiological Inorganic Organic - The main group(s) of water contamminants is (are) Patient exposure to water is 25 times greater - Water can be considered safe for drinking, but not necessarily safe for dialysis treatment because the True - Aluminum, fluoride, and chloramine chemicals are added by municipalities to drinking water supplies Impurities and toxins can foul dialysis machines. Patients are exposed to a large amount of water. Impurities may enter the blood through the dialyzer and can cause toxicity. Calcium and magnesium can cause a hard water syndrome. - What are reasons for water treatment in dialysis units Hemolysis - Chloramine exposure during hemodialysis may cause True - Softening is defined as the exchange of calcium and magnesium ions for sodium ions.
