AG FR Series


Brackish Water RO Elements

The A-Series family of proprietary thin-film reverse osmosis membrane is characterized by high flux and relatively high sodium chloride rejection. AG FR brackish water elements are selected when durability and cleaning effectiveness are important. The AG FR membrane element is specifically designed with a larger feed spacer to enhance feed flow channels, maximizing the element energy efficiency and cleaning efficiency.

1Please refer to Cleaning Guidelines Technical Bulletin TB1194
2SDI is measured on a non-linear scale using a 0.45 micron filter paper. Additionally, finer colloids, particulates and microorganisms that pass through the filter paper and not measured in the SDI test, will potentially foul the RO element. For performance consistency and project warranty, please use Winflows projection software and consult your GE representative
