Eco Platinum-440

Summary

Product identification

The FilmTec™ Eco Platinum-440 Element is a spiral-wound element featuring a polyamide thin-film composite membrane. It is designed to offer a unique combination of low energy consumption and high salt rejection, making it suitable for reverse osmosis plant managers and operators dealing with controlled pre-treatment waters.

Key benefits include:

• Offers FilmTec™ Elements' industry-leading benefits coupled with a unique combination of low energy and high salt rejection.
• Provides improved hydraulic balance which enables system energy savings.
• Delivers excellent silica, boron, nitrate, TOC, and ammonium rejection.
• Provides increased active area with effective cleaning performance, robustness, and durability due to its widest cleaning pH range (1-13) and chemical tolerance.

Performance Specifications

• Active Area: 440 ft² (41 m²)
• Feed Spacer: 28-LDP
• Permeate Flow Rate: 12,650 GPD (48 m³/d)
• Typical Stabilized Salt Rejection: 99.7%
• Minimum Salt Rejection: 99.4%

Performance data is based on standard test conditions: 2,000 ppm NaCl, 150 psi (10.3 bar), 77°F (25°C), pH 8, 15% recovery. Flow rates for individual elements may vary by ±15%. Stabilized salt rejection is generally achieved within 24-48 hours of continuous use.

Operating limits

• Maximum Operating Temperature: 113°F (45°C)
  • 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

Feed water

• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • The presence of free chlorine and other oxidizing agents can cause premature membrane failure. DuPont Water Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure.

Mechanical / hydraulic

Dimensions

• A: 40.0 in (1,016 mm)
• B (ID): 1.125 in (29 mm)
• C: 7.9 in (201 mm)

This element is designed to fit a nominal 8-inch (203-mm) I.D. pressure vessel.

Important Considerations

The use of this product, in and of itself, does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
