  • Membrane Chemistry: Proprietary TFC polyamide
  • Membrane Type: TFC-HR membrane
  • Construction: Spiral-wound with fiberglass outerwrap
  • Applications: High rejection for brackish water treatment
  • Available Lengths: 40” (1,016 mm) with standard or high area construction, or 60” (1,524 mm) Magnum® length.

This summary focuses on the 8832 HR-575 Magnum® model.

Specifications

Performance is based on testing a 2,000 mg/l NaCl solution at 225 psi (1,550 kPa) applied pressure, 20% recovery (for Magnum elements), 77°F (25°C), and pH 7.5. Individual element permeate flows may vary +20%/-15%. Minimum chloride ion rejection is 99.2%.

  • Model: 8832 HR-575 Magnum®
  • Part Number: 8883205
  • Permeate Flow: 15,000 gpd (56.8 m³/d)
  • Chloride Rejection: 99.5%
  • Membrane Area: 575 ft² (53.4 m²)

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)
  • Maximum Differential Pressure per Element: 15 psi (104 kPa) for 60” (1,524 mm) long elements (10 psi (69 kPa) for 40” elements)
  • Maximum Differential Pressure per Vessel: 60 psi (414 kPa)
  • Permeate Pressure Limit: Should not exceed feed-concentrate pressure by more than 5 psi (34 kPa)
  • Allowable pH (continuous operation): 4 – 11
  • Allowable pH (short-term cleaning): 2.5 – 11
  • Maximum Recovery (60” elements): Approximately 20% (site and application specific)

Feed water

  • Maximum Feed Turbidity: 1 NTU (feedwater >0.2 NTU often requires frequent cleanings)
  • Maximum Feed Silt Density Index (SDI, 15 minute): 5.0
  • Maximum Continuous Free Chlorine: <0.1 mg/l
  • Chemical Tolerance - Free Chlorine: Approximately 1,000 ppm-hours at 77°F (25°C), pH 8. Intentional exposure to free chlorine or other oxidizing agents (permanganate, ozone, bromine, iodine) is not recommended.
  • Chemical Tolerance - Chloramines: Approximately 60,000 ppm-hours at 77°F (25°C), pH 8, in the absence of free chlorine.
  • Cationic Polymers and Surfactants: Exposure to these chemicals is not recommended due to potential for irreversible fouling.

Mechanical / hydraulic

  • Feed Spacer Thickness: 31/28 mil (0.8/0.7 mm)
  • Lubricants: Only recommended silicone lubricant (or approved equivalent), water, or glycerin should be used for O-rings and brine seals. Petroleum or vegetable-based oils may damage the element and void the warranty.
