Purified Water Requirement: Dialysis requires purified water to make dialysate and to flush and reprocess dialyzers.Contaminant Removal: Patients undergoing dialysis lack the protection of stomach acid and healthy kidneys, which in healthy individuals remove contaminants from water.Direct Blood Contact: During dialysis, patients’ blood comes in direct contact with large volumes of water through the dialyzer membrane, making it crucial to use contaminant-free water.Health Risks: Contaminated dialysis water can lead to diseases or even death, hence the need for rigorous water treatment.
