Specifications for 3838 HFM-180

• Active Membrane Area: 49 ft² (4.6 m²) with HYV/T Spacer (62 mil)

Operating limits

• Typical Operating Pressure: 30 - 120 psi (2.1 - 8.3 bar)
• Maximum Operating Pressure: 140 psi (9.7 bar)
• Recommended Operating Temperature Range: 41 - 130°F (5 - 54°C)
• Maximum Operating Temperature:
  • At pH 6.0 - 7.5: 150°F (65.5°C)
  • At pH 3.5 - 6.0: 140°F (60°C)
  • At pH 2.0 - 3.5 and 7.5 – 10.0: 130°F (54°C)
• Cleaning Temperature Range: 105 - 130°F (40 - 54°C)
• Allowable pH - Continuous Operation: 2.5 - 10.5
• Allowable pH - Clean-In-Place (CIP): 1.5 - 11.0
• Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time. Reverse pressure will damage the membrane.
• Design Pressure Drop Per Element:
  • N spacer: 12-15 psi (0.8-1.0 bar)
  • V spacer: 15-20 psi (1.0-1.4 bar)
  • H or F spacer: 15-25 psi (1.0-1.7 bar)
• Design Pressure Drop Per Vessel (3 in series):
  • N spacer: 36-45 psi (2.5-3.1 bar)
  • V spacer: 45-60 psi (3.1-4.1 bar)
  • H or F spacer: 45-75 psi (3.1-5.2 bar)
• Design Pressure Drop Per Vessel (4 in series):
  • N spacer: 48-60 psi (3.3-4.1 bar)
  • V spacer: 60-75 psi (4.1-5.2 bar)
  • H or F spacer: 45-75 psi (3.1-5.2 bar)
• Chlorine Exposure during CIP:
  • Recommended exposure time: 30 minutes per day.
  • Residual chlorine concentration: 150 ppm @ pH 10.5 or higher.
  • Maximum chlorine concentration: 200 ppm.
  • Chlorine should only be added after pH has been adjusted to 10.5 or higher.
• Chemical Incompatibilities: Exposure to cationic (positively charged) polymers or surfactants is not recommended and will void the warranty. Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide will accelerate membrane degradation.
• Lubricants: Use only water or glycerin to lubricate seals during installation. Petroleum or vegetable-based oils or solvents may damage the element and void the warranty.

Product water

• Pure water flux: 2.0-4.0 gfd/psi (50-100 l/m²/h/bar) at 77°F (25°C).
