Centralized water supply system for hospitals: RO water solution for dialysis
1. Key standards for hospital water
Why are ordinary water purification systems not applicable?
⚠️ Dialysis water: must meet AAMI/ISO 13959 standards (endotoxin <0.25 EU/mL)
⚠️ Operating room water: needs to meet WHO sterility requirements (microorganisms <10 CFU/100mL)
⚠️ Pipeline safety: prohibit the use of lead/zinc-containing materials (to prevent heavy metal precipitation)
Industry data: 90% of hospital infections are related to water quality (CDC report).
2. Dialysis-specific RO system design
Core configuration to ensure safety
① Three-stage purification process
1. Pre-treatment:
• Pre-treatment: Multi-media filtration (removal of suspended solids)
• Activated carbon adsorption (eliminate chloramine)
2. RO host:
• Sanitary 316L stainless steel membrane shell
• Desalination rate ≥ 99
3. Post-treatment:
• UV + ultrafiltration (0.1μm) double sterilization
② Aseptic piping system
1. Material: EPDM rubber / 316L stainless steel
2. Design:
• Circulation flow rate >1.5m/s (to prevent biofilm)
• Zero dead space connection (HTM 01-05 compliant)
3. Successful Cases: Renovation of a tertiary hospital
Upgrading project of blood dialysis center of a hospital in Beijing
Original Issue:
• Endotoxin fluctuation (0.3-1.8 EU/mL)
• Unqualified dialysis water 3 times a year
Solution:
• Installation of 10T/H medical RO system
• Replaced all stainless steel recirculation lines
Results:
✅ Endotoxin stabilization <0.1 EU/mL
✅ 100% compliance for 18 consecutive months
✅ JCI accreditation inspection passed
