How is the quality of the purified water ensured for patient safety? Safety isn't just about having the equipment; it's about rigorous, ongoing monitoring. This is ensured through a strict protocol: Continuous Monitoring: The system itself has inline meters that constantly check the water's purity (measured as conductivity) and the integrity of the RO membrane (measured as rejection rate). If levels fall out of range, the system will automatically divert water to drain, preventing unsafe water from reaching the patients. Regular Disinfection: The entire distribution loop, including storage tanks and pipes, is disinfected frequently (often daily or weekly) with chemical sterilants or hot water to prevent bacterial biofilm from forming. Routine Testing: As per strict regulations (like AAMI standards), water samples are collected from specific points in the system, including the farthest outlet from the RO, at scheduled intervals. These samples are tested for bacterial growth (microbial culture) and endotoxin levels to ensure they remain within safe limits. https://www.molewater.com/hemodialysis-water-treatment-system
