AG-90 LF

Summary

Product identification

The AG HR LF Series comprises A-Series thin-film reverse osmosis (TFM) elements designed for treating impaired water where high rejection is desired. These membranes feature a more neutral charge, which helps reduce interactions with potential foulants in surface water or tertiary effluent.

Product water

The following performance data 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.

• Average NaCl rejection: 99.8%
• Minimum NaCl rejection: 99.3%
• Average permeate flow:
  • AG-90 LF: 1875 gpd (7.1 m³/day)
  • AG-400 LF, 34: 10500 gpd (39.7 m³/day)
  • Individual flow rate may vary +25%/-20%.
