The PRO-XR1 is a unique spiral wound membrane customized specifically for industrial process applications. This membrane is based on existing Hydranautics high performance membrane products which have been specially designed to treat a variety of challenging industrial feed streams.
| Permeate Flow (Nominal) PRO-XR1: | 11,500 gpd (43.5 m3/d) |
| Salt Rejection PRO-XR1: | 99.8% (99.5% minimum) |
| Test Conditions PRO-XR1: | 2,000 ppm NaCl solution |
| 225 psig (1.55 MPa) Applied Pressure | |
| 77°F (25°C) Operating Temperature | |
| 15% Permeate Recovery | |

The Specified Performance is based on data taken after a minimum 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 PRO-XR1: | Low Fouling Spiral Wound |
| Membrane Polymer PRO-XR1: | Composite Polyamide |
| Neutrally Charged Surface | |
| Membrane Active Area PRO-XR1 | 400 ft2 (37.2 m2) |
| Feed Spacer: | 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.
