The Hydranautics® PRO-XP series is a set of ultra high-pressure spiral wound membranes customized specifically for challenging industrial process applications such as brine dewatering. These membranes are based on existing Hydranautics high performance membrane products which have been specially designed to treat a variety of industrial feed streams including high fouling, high TDS, or chemically aggressive feeds.
| Permeate Flow PRO-XP1: | 8,000 gpd (30.3 m3/d) |
| Salt Rejection PRO-XP1: | 99.8% (99.7% minimum) |
| Test Conditions PRO-XP1: | 32,000 ppm NaCl solution |
| 800 psig (5.5 MPa) Applied Pressure | |
| 77 °F (25 °C) Operating Temperature | |
| 10% 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% to +25% from the value specified. Expect as much as 25-45% flux loss after operating near high pressure limits.
| Configuration PRO-XP1: | Spiral Wound |
| Membrane Polymer PRO-XP1: | Composite Polyamide |
| Membrane Active Area PRO-XP1: | 365 ft2 (33.9 m2) |
| Feed Spacer PRO-XP1: | 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.
