Filmtec (BW30-2540) Brackish Water Membrane 850 GPD 2.5" x 40"
Brackish Water RO Membrane 850 GPD
The Filmtec BW30-2540 delivers consistent performance in compact commercial systems where space and flow requirements favor a 2.5" diameter element. Its hard shell exterior provides structural integrity in multi-element housings with three or more membranes, withstanding higher pressure drops than standard wound configurations.
Performance Data
| Membrane Type | Thin-Film Composite (TFC) Polyamide |
| Dimensions | 2.5" diameter × 40" length |
| Active Surface Area | 28 ft² (2.6 m²) |
| Permeate Flow Rate | 850 GPD (3.2 m³/d) |
| Salt Rejection | 99.5% (stabilized) |
| Test Conditions | 2000 ppm NaCl, 225 psig, 77°F, 15% recovery |
| Operating pH Range | pH 2-11 (continuous) |
| Cleaning pH Range | pH 1-13 |
| Construction | Hard shell exterior (fiberglass) |
| Flow Tolerance | ±20% per element |
System Requirements
The BW30-2540 is designed for light industrial and commercial brackish water RO systems with flow requirements under 1 GPM. Requires a 2.5" × 40" membrane housing with appropriate end caps and brine seal assembly. Hard shell construction makes this element ideal for multi-element vessels containing three or more membranes, where internal pressure differentials demand greater structural strength than standard tape-wrapped elements. Compatible with all Filmtec-specified cleaning protocols across the full pH 1-13 range. Verify feed water chemistry and operating pressures match test conditions (225 psig, 2000 ppm TDS) for rated performance. Not intended for seawater desalination applications.
