Product water
The nominal rejection is reached after 48 hours of continuous operation on test solution. Minimal rejection refers to a new element after 20 minutes’ test on test solution. Test conditions: NaCl 1500 mg/l, P=1.55 MPa, T=25 °С, pH=7.5. Recovery -15%. Flow of each single element in a batch may vary for +25% / -15%.
