High productivity with excellent salt rejection
The FilmTec™ SW30-4040 is a 4″×40″ seawater RO element for small commercial desalination systems. It delivers a high flow of ~1,950 gpd (~7.4 m³/day) and salt rejection up to 99.7% (typical ≥99.4%), reducing operating costs by running at ~800 psi with excellent stability.
Key Features
- Active area: ~80 ft² (~7.4 m²)
- Permeate flow: ≈ 1,950 gpd (~7.4 m³/day)
- Salt rejection: up to 99.7% (typical ≥99.4%)
- Membrane type: Polyamide TFC, fiberglass shell
- Dimensions: 4″ × 40″ (≈ 99 × 1016 mm)
Operating Limits
- Operating pressure: 800 psi (~55 bar) — Max: 1,200 psi (83 bar)
- Temperature: up to 45 °C (113 °F)
- pH: 2–11 (continuous), 1–13 (cleaning ≤30′)
- Feed water SDI: ≤ 5 | Free chlorine: < 0.1 ppm
- Typical recovery: ~8% in seawater tests (32,000 ppm NaCl)
Certifications & Compliance
The materials comply with NSF/ANSI/CAN 61 for drinking water system components. Residual chlorine must be removed before feedwater enters the membrane (oxidative damage is not covered under warranty).
Note: Performance data is based on test conditions of 32,000 ppm NaCl, 25 °C, 8% recovery. Actual results will vary depending on system design, pretreatment, and operating conditions.
