Filmtec (SW30-4040) Seawater Membrane 1,950 GPD 4" X 40"
Seawater RO Membrane for High-Salinity Desalination
1,950 GPD commercial seawater reverse osmosis element engineered for consistent performance in demanding marine and coastal applications
The Filmtec SW30-4040 seawater membrane delivers 1,950 gallons per day from feedwater containing 32,000 ppm total dissolved solids, making it the workhorse element for船-based and land-based desalination systems. Automated precision fabrication ensures each element maintains stable rejection rates above 99.4%, reducing variability across multi-element arrays.
Performance Data & Operating Parameters
| Model Number | SW30-4040 |
| Dimensions | 4 inches × 40 inches |
| Active Membrane Area | 80 ft² (7.4 m²) |
| Permeate Flow Rate | 1,950 GPD (7.4 m³/day) |
| Salt Rejection | 99.4% stabilized |
| Test Conditions | 32,000 ppm NaCl, 800 psi, 77°F, 2% recovery |
| Operating Pressure | 800 psi (55 bar) maximum |
| Application | Seawater desalination |
| Flow Variance | ±20% per element |
System Integration & Housing Requirements
The Filmtec SW30-4040 element fits standard 4-inch diameter commercial membrane housings designed for 40-inch elements. This seawater membrane is engineered specifically for feedwater with TDS levels between 20,000 and 45,000 ppm and requires system operating pressure of 600–800 psi to achieve rated permeate flow. Compatible with commercial desalination systems using Dow Filmtec or equivalent 4040 seawater element configurations. Lower operating pressures may be used to reduce pump requirements and energy costs while accepting proportionally reduced flow rates.
