ESPA2-LD-4040
2,000 gpd (7.57 m3/d) 99.6% (99.4% minimum)
1500 ppm NaCl solution
150 psig (1.03 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 + or -20 percent from the value specified.
Low Fouling Spiral Wound Composite Polyamide
80 ft2 (7.43 m2)
34 mil (0.86 mm)
Packaging: All membrane elements are supplied with a brine seal, interconnector, and O-rings. Elements are enclosed in a sealed polyethylene bag containing less than 1.0% sodium meta-bisulfite solution, and then packaged in a cardboard box.
