Description
ESNA1-LF2-LD
Permeate Flow: 12,000 gpd (45.4 m3/d)
CaCl2 Rejection: 91%
CaCl2 Rejection (Minimum/Maximum): 80%/96%
* Expected calcium rejection for a typical 500 ppm well water is 93% at 13 gfd operating flux and 25ºC.
Test Conditions: 500 ppm CaCl2 solution
75 psig (0.52 MPa) Applied Pressure
77 F (25 C) Operating Temperature
15% Permeate Recovery
6.5 – 7.0 pH Range
*The Specified Performance is based on data taken after a minimum of 10 minutes of operation. Actual testing of elements may be done at conditions which vary from these exact values; in which case, the performance is normalized back to these standard conditions. Permeate flow for individual elements may vary -20 / +34 percent from the value specified.
