HED Group - We are proud to supply RO CPA3 membranes from Nitto Denko/ Hydranautics, the manufacturer, in Vietnam.
| Permeate Flow CPA3 | 11,000 gpd (41.6 m3/d) |
Salt Rejection CPA3
| 99.7% (99.6% minimum) |
| Test Conditions CPA3 | 1500 ppm NaCl solution |
225 psig (1.55 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 ±15 percent from the value specified.

| Configuration CPA3 | Spiral Wound |
| Membrane Polymer CPA3 | Composite Polyamide |
| Membrane Active Area CPA3 | 400 ft2 (37.2 m2) |
| Feed Spacer CPA3 | 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 and then packaged in a cardboard box. Wet membranes include a solution containing less than 1.0% sodium meta-bisulfite
