Fortilife CR100i

Summary

Product identification

The FilmTec™ Fortilife™ CR100i Element is a highly durable, contaminant-resistant, biofouling-resistant brackish water reverse osmosis (RO) element. It is designed for treating and recycling highly biofouling-prone waters, such as wastewater, utilizing an ultra-low pressure drop design and a robust, cleanable membrane chemistry.

• Product Type: Spiral-wound element with polyamide thin-film composite membrane
• Benefits:
  • Up to 10% less energy consumption at the same water productivity.
  • Up to 50% reduction in the number of cleanings.
  • Durable membrane with a cleaning tolerance over a wide pH range (pH 1-13) for consistent, long-lasting lifetime.
  • iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks.

Typical Properties

Test conditions for permeate flow and salt (NaCl) rejection are based on 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, and 15% recovery.

• Active Area: 400 ft² (37 m²)
• Permeate Flow Rate: 11,500 gpd (43.5 m³/d)
• Minimum Salt Rejection: 99.4%
• Stabilized Salt Rejection: 99.7%
• Element dP (typical): 0.1 bar (at 11,500 gpd permeate flow and 15% recovery)

Mechanical / hydraulic

• Dimensions (inches (mm)):
  • Feed Spacer: 34 mil
  • Net Length (A): 40.0 (1,016)
  • Individual Element Length with iLEC™ endcaps (B): 40.5 (1,029)
  • Diameter (C): 7.9 (201)
  • ID (D): 1.125 (29)
• Element designed to fit nominal 8-inch (203 mm) I.D. pressure vessel.

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 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
  • The presence of free chlorine and other oxidizing agents can cause premature failure; oxidation damage is not covered under warranty. Pretreatment for residual free chlorine removal is recommended.

Operation Guidelines

• Avoid abrupt pressure or cross-flow variations during start-up, shutdown, or cleaning.
• Start-up Sequence:
  • Feed pressure should be increased gradually over a 30-60 second timeframe.
  • Cross-flow velocity at the set operating point should be achieved gradually over 15-20 seconds.
• Permeate obtained from the first hour of operation should be discarded.
• The use of this product does not inherently guarantee the removal of cysts and pathogens; effective reduction depends on complete system design, operation, and maintenance.
