Eco Pro-400i

Summary

Product identification

• Product Name: FilmTec™ Eco Pro-400i Element
• Product Type: Spiral-wound element with polyamide thin-film composite membrane
• Description: Designed for reverse osmosis plant managers and operators dealing with challenging waters. It offers high salt rejection at low pressure, achieves reduction of fouling impact by minimized pressure drop, and delivers excellent rejection of silica, boron, nitrate, total organic carbon (TOC), and ammonium. The element provides effective cleaning performance, robustness, and durability due to its wide cleaning pH range (1-13) and chemical tolerance. It includes iLEC™ interlocking end caps, which help reduce system operating costs and the risk of o-ring leaks.

Typical Performance

• FilmTec™ Eco Pro-400i Element

  • Active Area: 400 ft² (37 m²)
  • Feed Spacer: 34-LDP (Note: 'Thickness (mil)' is stated in original table header, but '34-LDP' is the value given, suggesting a model or type identifier, not a numerical thickness.)
  • Permeate Flow Rate: 11,500 GPD (43.5 m³/d)
  • Typical Stabilized Salt Rejection: 99.7%
  • Minimum Salt Rejection: 99.4%

• Standard Test Conditions: Permeate flow and salt (NaCl) rejection are based on the following standard test conditions:

  • NaCl Concentration: 2,000 ppm
  • Applied Pressure: 150 psi (10.3 bar)
  • Temperature: 77°F (25°C)
  • pH: 8
  • Recovery: 15%

• Notes:

  • Flow rates for individual elements may vary by no more than ±15%.
  • Stabilized salt rejection is generally achieved within 24-48 hours of continuous use.
  • Active area is guaranteed ±3%.

Mechanical / hydraulic

• Dimensions (Nominal):
  • Net Length (A, elements connected): 40.0 inches (1,016 mm)
  • Total Length (B, individual element with iLEC™ end caps): 40.5 inches (1,029 mm)
  • Diameter (C): 7.9 inches (201 mm)
  • Permeate Tube ID (D): 1.125 ID (29 ID)
• The element is designed to fit a nominal 8-inch (203-mm) I.D. pressure vessel.

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
  • Short-Term Cleaning (30 min.): 1 – 13
• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Tolerance: < 0.1 ppm
  • Note: Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Removal of residual free chlorine by pretreatment prior to membrane exposure is recommended.

Product Water (Additional Note)

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.
