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.
