Installation & Maintenance Tips

n

    n

  • Pre‑treatment is essential: feed water should meet SDI ≤ 5, free chlorine < 0.1 ppm.

    • n

  • On startup, flush the new membrane in accordance with manufacturer guidelines; discard initial permeate.

    • n

  • Monitor performance: track permeate flow and salt rejection — significant drops may signal fouling, scaling or membrane damage.

    • n

  • Maintenance: Follow cleaning schedule, respect pH and temperature limits; replace when performance degrade.

    • n

  • Storage: If offline, keep the membrane wet or store in appropriate sterilant to avoid drying out.
