AG HR LF Series
High Rejection Low Fouling Brackish Water RO Elements
The A-Series family of proprietary thin-film reverse
osmosis membrane are characterized by high flux and
high sodium chloride rejection. AG HR LF Brackish
Water Elements are selected for the treatment of im-
paired water when high rejection is desired. The AG
HR LF membrane features a more neutral charge and
therefore reduces interactions with potential foulants
present in surface water or tertiary effluent.
Table 1: Element Specification
1 Average salt rejection after 24 hours operation. Individual flow rate may
vary +25%/-20%.
2 Testing conditions: 2,000ppm NaCl solution at 225psi (1,550kPa) operating
pressure, 77°F (25°C), pH7 and 15% recovery.

Table 2: Operating and CIP parameters
3 SDI 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 Filters with
Membranes representative.
