Test Conditions (for KM 8040-C (2,3)): test solution of NaCl 32 g/l, P=5,5 MPa, T=25°C , pH=7,5. Recovery – 10%
Test Conditions (for KM 4040-C): test solution of NaCl 32 g/l, P=5,5 MPa, T=25°C , pH=7,5. Recovery – 8%
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.
