NOTE:

  • 1. The above values are normalized to the following test conditions: 2,000 ppm NaCI, 10.3 bar (150 psi), 25°C(77°F), pH 8, 15% recovery. Permeate flows for individual elements may vary -/+ 15%.
  • 2. The above values are normalized to the following test conditions: 2,000 ppm NaCI, 15.5 bar (225 psi), 25°C(77°F), pH 8, 15% recovery. Permeate flows for individual elements may vary -/+ 15%.
  • 3. The above values are normalized to the following conditions: 2,000 ppm NaCl, 15.5 bar (225 psi), 25°C (77°F), pH 6.5 – 7.0, 15% recovery. Permeate flows for individual elements may vary +/- 20%.
