Additional Information

  • Treat RO Elements with care; do not drop the element.
  • Each RO Element is wet tested, preserved in a 1% weight sodium bisulfite solution, and vacuum packed in oxygen barrier bags.
  • During storage, avoid freezing and direct sunlight. The temperature should be below 35 °C (95 °F).

After Installation

  • Keep the RO Elements wet, and use a compatible preservative for storage duration longer than 7 days.
  • During the inital start up, discharge the first permeate to drain for 30 min.
  • Permeate back pressure should not exceed feed pressure at any time.
  • The RO Elements shall be maintained in a clean condition, unfouled by particulate matter or precipitates or biological growth.
  • Consider cleaning, if the pressure drop increases by 20% or water permeability decreases by 10%.
  • Use only chemicals which are compatible with the membrane.
