TFC-4040-XR 4" High Rejection, Low Pressure

Summary

Product identification

• Product Name: FLUID SYSTEMS® TFC®- XR 4” ELEMENT
• Description: High Rejection, Low Pressure RO Element for Brackish Water
• Membrane Chemistry: Proprietary TFC® polyamide
• Membrane Type: TFC®-XR membrane
• Construction: Spiral wound with fiberglass outerwrap
• Applications: High rejection for brackish water treatment
• Model: 4040-XR
• Part Number: 8482001

Specifications (Nominal)

• Permeate Flow: 2,200 gpd (8.3 m³/d)
• Chloride Rejection: 99.75%
• Active Membrane Area: 85 ft² (7.9 m²)
• Feed Spacer: 28 mil (0.7 mm)

Test Conditions: 2,000 mg/l NaCl solution at 325 psi (2,240 kPa) applied pressure, 15% recovery, 77°F (25°C), and pH 7.5. Individual element permeate flows may vary +20/-15% from nominal values. Minimum chloride ion rejection is 99.2% under the specified test conditions.

Operating limits

• Typical Operating Pressure: 225 - 450 psi (1,550 - 3,100 kPa)
• Maximum Operating Pressure: 600 psi (4,140 kPa)
• Maximum Operating Temperature: 113°F (45°C)
• Maximum Cleaning Temperature: 113°F (45°C)
• Permeate Pressure: Should not exceed feed-concentrate pressure by more than 5 psi (34 kPa) at any time.
• Maximum Differential Pressure per Element: 10 psi (69 kPa)
• Maximum Differential Pressure per Vessel: 60 psi (414 kPa)
• Allowable pH – Continuous Operation: 4 - 11
• Allowable pH – Short Term Cleaning: 2.5 - 11 (It is recommended to limit exposure to this extended pH range to 4 hours, once per month.)
• Recovery: Single element recovery is approximately 15% per element (site and application specific).

Feed water

• Maximum Continuous Free Chlorine: <0.1 mg/l
  • TFC-XR membrane has a free chlorine tolerance of approximately 1,000 ppm-hours based on testing 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.
  • Chloramine tolerance is approximately 60,000 ppm-hours in the absence of free chlorine based on testing at 77°F (25°C), pH 8.
• 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
• Chemical Tolerance: Exposure to cationic (positively charged) polymers or surfactants during operation or cleaning is not recommended as it may cause irreversible fouling.

Mechanical / hydraulic

• Nominal Dimensions (for 4040-XR):
  • A: 40 inches (1,016 mm)
  • B: 4 inches (101.6 mm)
  • C: 0.75 inches (19.0 mm)
  • D: 1.0 inches (25.4 mm)
• Weight: 10 lbs (4.5 kg)
• Associated Parts:
  • Interconnector Part Number: 0035267
  • O-ring Part Number: 0035458
  • Brine Seal Part Number: 0035702
• Lubricants: 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.
