Eco Pro-440

Summary

Product identification

The FilmTec™ Eco Pro-440 Element is a spiral-wound element featuring a polyamide thin-film composite membrane. It is designed for reverse osmosis plant managers and operators who use controlled pre-treatment waters and require advanced membrane treatment for high water purity and low energy consumption.

Key features include:

• High salt-rejection at low pressure.
• Excellent silica, boron, nitrate, TOC, and ammonium rejection.
• Increased active area with effective cleaning performance, robustness, and durability due to its wide cleaning pH range (1-13) and chemical tolerance.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • Note: Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
• Maximum Operating Pressure: 600 psig (41 bar)
• Maximum Element 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

Feed water

DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure, as its presence can cause premature membrane failure.

Product water

This element offers high water purity and high rejection rates for various contaminants.

Performance based on standard test conditions (2,000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8, 15% recovery):

• Typical Permeate Flow Rate: 12,650 GPD (48 m³/d)
• Typical Stabilized Salt Rejection: 99.7%
• Minimum Salt Rejection: 99.4%

Salt rejection is generally achieved within 24-48 hours of continuous use.

Note on Cysts and Pathogens: The use of this product does not guarantee the removal of cysts and pathogens from water. Effective reduction depends on the complete system design, operation, and maintenance.
