AG-400 FR H

Summary

Product identification

The AG FR H Series of thin-film reverse osmosis (RO) elements are designed for challenging brackish water applications requiring high rejection and fouling resistance. These elements combine advanced chemistry and manufacturing to deliver differentiated performance in both ionic rejection and rejection of uncharged or lightly charged species such as silica (SiO₂).

The AG FR H Series membranes have NSF/ANSI/CAN 61 certification for use in municipal applications, including surface water treatment for drinking water, with intent to remove emerging contaminants such as PFAS compounds.

• Membrane: Thin-film membrane (TFM), polyamide

Handling and storage

Each RO element is wet tested, preserved in a 1% weight sodium bisulfite solution, and vacuum packed in oxygen barrier bags.

• 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 durations longer than 7 days.
  • During initial start-up, discharge the first permeate to drain for 30 minutes.
  • Permeate back pressure should not exceed feed pressure at any time.
  • Maintain elements in a clean condition, unfouled by particulate matter, precipitates, or biological growth.
  • Consider cleaning if the pressure drop increases by 20% or water permeability decreases by 10%. Use only chemicals compatible with the membrane.
