Model Specifications (8040-SR100-260)

• Part Number: 8872201
• Nominal Permeate Flow: 4,500 gpd (17.0 m³/d)
• MgSO₄ Rejection: > 99.0 percent
• Active Membrane Area: 260 ft² (24.1 m²)
• Feed Spacer: 46 mil (1.2 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.
• Performance Variation: Individual element permeate flows may vary +20/-15% from nominal values.

Operating limits

• Typical Operating Pressure: 200 - 600 psi (1,380 - 4,140 kPa). Typical operating pressure for TFC SR100 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)
• Maximum Continuous Free Chlorine: <0.1 mg/l
• 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.
• Single Element Recovery: Approximately 15% per element.

Feed water

• Maximum Feed Turbidity: 1 NTU
• Maximum Feed SDI (15 minute test): 5.0
• Chemical Tolerance (Free Chlorine): Approximately 2,000 ppm-hours (based on testing at 77°F (25°C), pH 8). Exposure to free chlorine or other oxidizing agents (e.g., permanganate, ozone, bromine, iodine) is not recommended.
• Chemical Tolerance (Chloramine): Approximately 60,000 ppm-hours (based on testing at 77°F (25°C), pH 8, in the absence of free chlorine).
• Cationic Polymers and Surfactants: Exposure to these chemicals during operation or cleaning is not recommended as the membrane may be irreversibly fouled.

Mechanical / Hydraulic

• Nominal Dimensions (Model 8040-SR100-260):
  • A: 40 inches (1,016 mm)
  • B: 8 inches (203 mm)
  • C: 1.125 inches (29 mm)
• Weight (Model 8040-SR100-260): 44 lbs (20 kg)
• Accessory Part Numbers:
  • Interconnector: 0035260
  • O-ring: 0035464
  • Brine Seal: 0035705
• Lubricants: For element loading, use only recommended silicone lubricant (or approved equivalent), water, or glycerin to lubricate O-rings and brine seals. Petroleum based lubricants or vegetable based oils may damage the element and void the warranty.
