Test Conditions (For KH 8040-C1M1): test solution of NaCl 1500 mg/l, P=1,55 MPa, T=25°C , pH=7,5. Recovery – 15%
Test Conditions (For KH 4040-C1M1): test solution of NaCl 1500 mg/l, P=1,55 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.
