Specified Performance：
Permeate Flow: 9,500 gpd (36 .0 m3/d)
CaCl2 Rejection: 93%
CaCl2 Rejection (Minimum/Maximum): 88%/97%
Expected calcium rejection for a typical 500 ppm well water is 96% at 13 gfd operating flux and 25ºC.
Test Conditions: 500 ppm CaCl2 solution
75 psig (0 .52 MPa) Applied Pressure
77 ℉ (25℃) Operating Temperature15% Permeate Recovery
