Specifications

Active Membrane Area (Note: not all combinations available)

• Membrane Characteristics: The membrane consists of a semipermeable polyethersulfone (PES) layer on a polyester backing material.
• Pure water flux (both MFK-601 and MFK-618): 2.0-4.4 gfd/psi at 77°F (25°C).

Operating limits

• Typical Operating Pressure: 30 - 120 psi (2.1 - 8.3 bar)
• Maximum Operating Pressure: 140 psi (9.7 bar)
  • Permeate pressure should not exceed baseline (concentrate) pressure at any time. Reverse pressure will damage the membrane.
• Typical Operating Temperature Range: 41 - 131°F (5 - 55°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: 131°F (55°C)
• Cleaning (CIP) Temperature Range: 104 - 122°F (40 - 50°C)
  • Maximum cleaning temperature is 122°F (50°C).
• Allowable pH - Continuous Operation: 2.0 - 10.0
• Allowable pH - Clean-In-Place (CIP): 1.8 - 11.0
• Design Pressure Drop Per Element:
  • N spacer: 5-15 psi (0.3-1.0 bar)
  • V spacer: 5-20 psi (0.3-1.4 bar)
  • H, F, D or E spacer: 10-20 psi (0.7-1.4 bar)
• Design Pressure Drop Per Vessel (3 In Series):
  • N spacer: 15-45 psi (1.0-3.1 bar)
  • V spacer: 15-60 psi (1.0-4.1 bar)
  • H, F, D or E spacer: 30-60 psi (2.1-4.2 bar)
• Water Quality for Cleaning & Diafiltration:
  • Maximum feed turbidity: 1 NTU
  • Maximum feed SDI: 5.0 (15-minute test)
• Chlorine and Chemical Exposure:
  • Recommended chlorine exposure time: 30 minutes per day.
  • Residual chlorine concentration during cleaning cycle (CIP) should be 150 ppm @ pH 10.5 or higher.
  • Chlorine concentration should never exceed 200 ppm.
  • Chlorine should only be added to the cleaning solution after the pH has been adjusted to 10.5 or higher.
  • Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide will accelerate membrane degradation.
• Cationic (Positively Charged) Polymers and Surfactants: Exposure to these chemicals during operation or cleaning is not recommended and will void the warranty, as MFK membranes may be irreversibly fouled.
• Lubricants: For module installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the element and will void the warranty.
