• Municipal Water Purification: Ensures high-quality water for public and private water systems.

Typical Properties

• Test Conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, and 15% recovery. Individual flow rates may vary by ±15%.

• Note: Sales specifications may change with design revisions.

Suggested Operating Conditions

The BW30 PRO-400 Reverse Osmosis Membranes are designed for reliable performance in challenging conditions:

• Note: The maximum temperature for continuous operation above pH 10 is 95°F (35°C).

• Important: Oxidation damage is not covered under warranty. DuPont recommends dechlorinating feedwater before membrane exposure.

Important General Information

To ensure the optimal performance and longevity of the BW30 PRO-400 Reverse Osmosis Membranes, follow these guidelines:

• Moisture Maintenance: Keep elements moist after initial wetting.

• System Operation: Follow the FilmTec™ Reverse Osmosis / Nanofiltration Elements Operation Excellence guidelines for successful RO system operation.

• Biological Growth Prevention: During prolonged shutdowns, immerse membranes in a preservative solution.

• Handling and Compatibility: The customer is fully responsible for the effects of incompatible chemicals and lubricants on the membranes.

System Operation and Start-Up Sequence

• Avoid static permeate-side backpressure during operation.

• Permeate from the first hour should be discarded.

• Effective cyst and pathogen removal depend on system design and maintenance practices.
