How Do RO Systems Meet AAMI & ISO Standards for Hemodialysis Water?
AAMI and ISO set strict standards for hemodialysis water—but how do RO systems ensure compliance with these rigorous rules?
First, RO targets specific contaminants at levels mandated by the standards. For example, AAMI limits aluminum to 0.01 mg/L and lead to 0.005 mg/L; RO removes >98% of heavy metals, easily meeting these thresholds. It also eliminates >99% of bacteria/endotoxins, aligning with ISO’s requirement for ultra-low microbial counts.
RO also handles dissolved solids: AAMI restricts sodium to 70 mg/L and sulfate to 100 mg/L; RO’s >95% removal rate for TDS ensures these limits are never exceeded. Unlike basic filters, RO doesn’t just reduce contaminants—it strips them to levels safe for patients, even during long-term dialysis.
Additionally, RO systems support documentation: their real-time monitoring logs water quality data, which facilities need to prove compliance during audits. When paired with regular maintenance (e.g., membrane checks), RO becomes a reliable way to meet AAMI/ISO’s demands.
Without RO, meeting these standards would be nearly impossible—its precision and power are what make it the gold standard for dialysis water. Click here to know more.
