Dupont Filmtec BW Membranes

• Membrane Type: The membranes are a polyamide thin-film composite in a spiral-wound configuration.
• High Performance: They offer high permeate flow and high salt rejection, typically achieving a stabilized salt rejection of 99.5%. This ensures high-quality purified water, often used for drinking water and industrial processes.
• Durability and pH Tolerance: One of the most notable features is their robustness and durability, which allows for a wide cleaning pH range of 1-13. This tolerance is critical for effective cleaning and can help extend the lifespan of the membrane, especially when dealing with waters that cause scaling or fouling.
• Operating Conditions: The membranes are designed to operate under specific conditions to ensure optimal performance. Typical operating parameters include:
  • Maximum Operating Temperature: 113°F (45°C)
  • Maximum Operating Pressure: 600 psi (41 bar)
  • Continuous Operation pH Range: 2-11
  • Maximum Feed Silt Density Index (SDI): SDI 5
  • Free Chlorine Tolerance: < 0.1 ppm

The BW series is utilized in a wide range of applications, including:

• Municipal drinking water production
• Industrial water demineralization (e.g., for power generation, steel, and chemical industries)
• Process water production (e.g., for food and beverage, electronics, and pharmaceutical industries)
• Boiler feedwater treatment
