TFC-8040-SR100-400 Low Pressure Nanofiltration

Summary

Product identification

• Product Name: FLUID SYSTEMS® TFC®- SR™100 8” ELEMENT
• Type: Low Pressure, Selective Rejection Nanofiltration Elements
• Membrane Chemistry: Proprietary TFC® polyamide
• Membrane Type: SR™100 – selective rejection nanofiltration membrane
• Construction: Spiral wound with fiberglass outerwrap
• Applications: Sulfate and hardness removal from seawater, removal of color and organics from ground water, softening and de-ashing.
• Model: 8040-SR100-400
• Part Number: 8872202

Performance Specifications

• Nominal Permeate Flow: 6,200 gpd (23.5 m³/d)
• Rejection (MgSO₄): > 99.0 percent
• Active Membrane Area: 400 ft² (37.2 m²)
• Feed Spacer: 28 mil (0.7 mm)

Test Conditions: 5,000 mg/l MgSO₄ in deionized water at 95 psi (655 kPa) applied pressure, 15% recovery, 77°F (25°C), pH 7.5.

Note: Individual element permeate flows may vary +20/-15% from the nominal values. Performance is highly dependent on water chemistry, temperature, pH, and solution concentration; pilot studies are recommended.

Operating limits

• Typical Operating Pressure: 200 - 600 psi (1,380 - 4,140 kPa). Typical operating pressure for systems is in the range of 150 psi (1,035 kPa) to 250 psi (1,725 kPa).
• Maximum Operating Pressure: 600 psi (4,140 kPa)
• Maximum Operating Temperature: 122°F (50°C)
• Maximum Cleaning Temperature: 113°F (45°C)
• Allowable pH – Continuous Operation: 4 - 10
• Allowable pH – Short Term Cleaning: 1.7 – 11.5 (limit exposure to 4 hours, once per month)
• Maximum Differential Pressure Per Element: 10 psi (69 kPa)
• Maximum Differential Pressure Per Vessel: 60 psi (414 kPa)
• Permeate Pressure: Should not exceed feed-concentrate pressure by more than 5 psi (34 kPa) at any time.
• Recovery: Maximum recovery is site and application specific; single element recovery is approximately 15%.

Feed water

• Maximum Feed Turbidity: 1 NTU (feedwater with turbidity greater than 0.2 NTU generally results in frequent cleanings)
• Maximum Feed SDI (15 minute test): 5.0
• Maximum Continuous Free Chlorine: <0.1 mg/l

Chemical Tolerance

• Free Chlorine/Oxidizing Agents: Not recommended. Free chlorine tolerance is approximately 2,000 ppm-hours at 77°F (25°C), pH 8. This tolerance may be significantly reduced if catalyzing metals (e.g., iron) are present or if pH and/or temperature differ. Sodium metabisulfite (without catalysts such as cobalt) is the preferred reducing agent.
• Chloramines: Tolerance of approximately 60,000 ppm-hours in the absence of free chlorine, based on testing at 77°F (25°C), pH 8.
• Cationic (Positively Charged) Polymers and Surfactants: Exposure to these chemicals during operation or cleaning is not recommended, as irreversible fouling may occur.

Nominal Dimensions and Weight

• Associated Parts:
  • Interconnector: 0035260
  • O-ring: 0035464
  • Brine Seal: 0035705

Note: Dimensions are for reference only and should not be interpreted as accurate specifications.

Element Loading

For element loading, use only the recommended silicone lubricant (or approved equivalent), water, or glycerin to lubricate O-rings and brine seals. The use of petroleum-based lubricants or vegetable-based oils may damage the element and void the warranty.
