BW30-PRO-2540

Summary

Product Identification

This document describes the FilmTec™ BW30 PRO-2540 reverse osmosis membrane element.

• Part Number: 12081023

Key Features

• Delivers consistent water quality and higher rejection and flow than previous generation FilmTec™ BW30 product
• Based on historical FilmTec™ BW30 industry-standard RO membrane with decades of proven performance
• Outstanding durability resulting in stable, long-term performance and sustainable water solutions
• Enhanced fouling protection
• Dry elements achieve quick stabilization

Key Applications

• Light industrial & Drinking water applications requiring stringent permeate quality
• Harsh feed water conditions

Typical Properties

• Permeate Flow Rate: 1,000 gpd (3.8 m³/d)
• Stabilized Salt Rejection: 99.7%
  • Minimum salt rejection is 99.5%.
  • Permeate flows for individual elements may vary +/-15%.

These properties are based on the following test conditions: 2,000 ppm NaCl, 225 psig (15.5 bar), pH 8, 77°F (25°C), and 15% recovery.

Mechanical / Hydraulic

Element Dimensions The BW30 PRO-2540 Elements fit nominal 2.5-inch I.D. pressure vessels. Dimensions are given as inches (mm):

• A: 40.0 (1,016)
• B: 1.19 (30.2)
• C: 0.75 (19)
• D: 2.4 (61)

Operating Limits

• Membrane Type: Polyamide Thin-Film Composite
• Maximum Operating Temperature: 113°F (45°C)
  • Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 600 psi (41 bar)
• Maximum Feed Flow Rate (2540 Elements): 6 gpm (1.4 m³/h)
• Maximum Pressure Drop: 15 psig (1.0 bar)
• pH Range - Continuous Operation: 2 - 11
• pH Range - Short-Term Cleaning (30 min.): 1 - 13
• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Residual free chlorine should be removed by pretreatment.

General Information

• Keep elements moist at all times after initial wetting.
• To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.
• The maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar).
• Avoid static permeate-side backpressure at all times.
• Permeate obtained from the first hour of operation should be discarded.
• Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, cleaning, or other sequences. During start-up, a gradual change is recommended:
  • Feed pressure should be increased gradually over a 30-60 second time frame.
  • Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds.
• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance.
