Standard test conditions:

The above performance is initial (data record after 30 minutes of operation), based on the following conditions:

1,500 ppm NaCl solution

150 psi (10.3 bar) operating pressure

25°C (77°F) operating temperature

15% permeate recovery

7.5-8 pH range

*Permeate flow for individual elements may vary but will be no more than ±15%.

**Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending on feed water characteristics and operating conditions.
