TW30-2540

Summary

Product identification

The FilmTec™ TW30-2540 is a tape-wrapped reverse osmosis (RO) element designed for commercial applications. It is described as an industry standard for reliable operation and production of high-quality water, offering an economical solution for commercial systems with one or two elements per housing.

Feed water

Test conditions for the TW30-2540 are based on a 2,000 ppm NaCl feed stream.

Product water

• Permeate Flow Rate (typical): 1,000 gpd (3.8 m³/d)
  • Based on test conditions: 77°F (25°C), 15% recovery, 225 psig (15.5 bar) applied pressure, and 2,000 ppm NaCl feed stream.
  • Permeate flows for individual elements may vary +/-20%.
• Stabilized Salt Rejection (typical): 99.5%
  • Based on test conditions: 77°F (25°C), 15% recovery, 225 psig (15.5 bar) applied pressure, and 2,000 ppm NaCl feed stream.

Mechanical / hydraulic

• Dimensions:
  • A: 40.0 inches (1,016 mm)
  • B: 1.19 inches (30.2 mm)
• Feed Spacer Thickness: 28 mil
• Elements fit nominal 2.5-inch I.D. pressure vessels.

General Operating Guidelines

• 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.
• Avoid static permeate-side backpressure at all times.
• Proper start-up of RO systems is essential to prepare membranes and prevent damage. This includes gradually increasing feed pressure over 30-60 seconds and gradually achieving cross-flow velocity over 15-20 seconds.
• The use of this product does not guarantee the removal of cysts and pathogens; effective reduction depends on the complete system design, operation, and maintenance.
