TEST CONDITIONS: test solution of NaCl 1500 mg/l, P=1,0 MPa, T=25°C , pH=7,5. Recovery - 15%
Nominal rejection is reached after 48 hours of continuous operation on test solution.
Minimal rejection of a new element after 20 minutes test on test solution.

1) During continuous work with pH over 10,5 the temperature must not exceed 35°С
2) Flow of each element in a batch may vary +/-15%
*In case of chemical cleaning with a solution pH exceeding 11,5 or at the temperature level more than 45°С please contact original manufacturer for consultation.
