AG HR LF series

Summary

Product identification

The AG HR LF Series is a family of proprietary thin-film reverse osmosis (RO) elements designed for high flux and high sodium chloride (NaCl) rejection. These A-Series membranes are selected for the treatment of impaired water where high rejection is desired. The AG HR LF membrane features a more neutral charge, which helps reduce interactions with potential foulants found in surface water or tertiary effluent.

• Membrane Type: A-Series, Thin-film membrane (TFM)
• Description: High rejection low fouling brackish water RO element

Element Specifications

Performance is based on testing conditions of 2,000 ppm NaCl solution at 225 psi (1,550 kPa) operating pressure, 77°F (25°C), pH 7, and 15% recovery. Average salt rejection is measured after 24 hours of operation. Individual flow rate may vary +25%/-20%.
