Industry Application Examples

Aerospace Sector
The International Space Station utilizes RO technology to achieve an 85% urine recovery rate, saving approximately CNY 320,000 per ton of water daily.

Electronics Industry
A semiconductor manufacturing plant implemented a two-stage RO + EDI system, producing 18.2 Mฮฉยทcm resistivity ultra-pure water, resulting in a 2.3% increase in wafer yield.

Medical Field
Dialysis water treated via RO achieves an endotoxin level of <0.03 EU/mL, fully compliant with YY0572-2015 standards.


Key Points for Operation & Maintenance

  1. Fouling Index Control

    • SDI15 must be consistently <3

    • Membrane flux should be maintained at 22โ€“28 GFD (for standard water sources)

  2. Chemical Cleaning Protocols

    • pH 2 Citric Acid for inorganic scale removal

    • pH 12 Sodium Hypochlorite + EDTA for biofilm removal
