Product water
The following specifications are based on test conditions using a NaCl 500 mg/l solution, P=0.7 MPa, T=25°С, pH=7,5, and a recovery of 15%. Flow of each single element in a batch may vary by +/-15%. Minimal rejection is measured after a 20-minute test of a new element. Nominal rejection is reached after 48 hours of continuous operation. During continuous work with pH over 10, the temperature must not exceed 35°С.
