HSRO-390-FF FilmTec Heat-Sanitizable Reverse Osmosis Membrane – Sanitary Full-Fit Design

Deliver high-purity water with confidence using the DuPont FilmTec™ HSRO-390-FF, a premium 8" x 40" heat-sanitizable RO membrane engineered for the most demanding sanitary applications. This full-fit (FF) element combines outstanding rejection and high flow with the unique ability to withstand hot water sanitization — eliminating chemical sanitizers and reducing operational complexity.

Key Specifications & Performance

• Permeate Flow: 9,000 gpd (34 m³/day) nominal (tested at 2,000 ppm NaCl, 150 psi)
• Stabilized Salt Rejection: 99.5%
• Active Membrane Area: 390 ft² (36 m²)
• Configuration: Full-Fit Sanitary Style (minimizes dead zones)
• Test Conditions: 2,000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8, 15% recovery

Membrane Type: Polyamide Thin-Film Composite Dimensions: 8" diameter x 40" length

Exceptional Features

• Heat Sanitizable: Withstands sanitization up to 185°F (85°C) at low pressure — ideal for maintaining sterility without harsh chemicals.
• High Flow & Efficiency: High active area supports lower flux operation (for reduced fouling) or fewer elements for the same output, saving on capital and footprint.
• Sanitary Full-Fit Design: Reduces stagnant areas where bacteria can accumulate, meeting stringent FDA-compliant requirements for high-purity systems.
• Robust Operating Limits:
  • Max Operating Pressure: 600 psi (41 bar)
  • Max Operating Temperature: 113°F (45°C) continuous
  • Max Sanitization Temperature: 185°F (85°C)
  • pH Range (Continuous): 2–11
  • Short-Term Cleaning pH: 1–12
  • Max SDI: 5.0
  • Free Chlorine Tolerance: < 0.1 ppm

Primary Applications

• Pharmaceutical, medical, and biotechnology purified water
• Food & dairy process water and permeate polishing
• Medical/dialysis water systems
• Any sanitary or high-purity RO application requiring heat sanitization and low extractables
