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).
Keep the RO Elements wet, and use a compatible preservative for storage duration longer than 7 days.
During the initial startup, discharge the first permeate to drain for 30 min.
Permeate backpressure should not exceed feed pressure at any time.
Consider cleaning, if the pressure drop increases by 20% or water permeability decreased by 10%.
Use only chemicals that are compatible with the membrane.
