Dairy-MF 3838 MFK-603-FYV

Summary

Product identification

• Product Description:
  • Membrane Chemistry: Proprietary semi-permeable polyethersulfone (PES)
  • Membrane Type: MFK™-603 with observed separation range of 0.1 micron
  • Construction: Sanitary spiral wound with net outer wrap
  • Regulatory Status: Conform to USDA 3-A standards and FDA regulations (CFR Title 21)
• Specifications:
  • KMS Part Number: 0757063, Model: 3838 MFK-603-FYV, Active Membrane Area: 33 ft² (3.0 m²), Feed Spacer: 80 mil (2.0 mm)
  • KMS Part Number: 0750703, Model: 8338 MFK-603-FYT, Active Membrane Area: 181 ft² (16.8 m²), Feed Spacer: 80 mil (2.0 mm)
• Membrane Characteristics:
  • The membrane used in these elements consists of a semipermeable polyethersulfone (PES) layer on a polyester backing material.
  • Pure water flux of the MFK-603 membrane is 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)
• Maximum Operating Temperature: 176°F (80°C) during process
• Cleaning (CIP) Temperature Range:
  • 104 - 122°F (40 - 50°C) for chlorine cleaning
  • 104 - 176°F (40 - 80°C) for cleaning not involving chlorine
• Allowable pH - Continuous Operation: 2.0 - 10.0
• Allowable pH - Clean-In-Place (CIP): 1.8 - 11.0
• Design Pressure Drop Per Element: 10-20 psi (0.7-1.4 bar)
• Maximum Pressure Drop Per Vessel: 60 psi (4.2 bar)
• Permeate Pressure: Permeate pressure should not exceed baseline (concentrate) pressure at any time (including online, off-line, and during transition). Reverse pressure will damage the membrane.
• Differential Pressure: The maximum differential pressure per module is listed on the reverse side of the original sheet for the different feed spacer elements. The maximum differential pressure for a housing is also listed.

Feed water

• Water Quality for Cleaning & Diafiltration: Refer to KMS “Water Quality Guidelines for CIP and Diafiltration” for more detailed information.
• Chlorine and Chemical Exposure:
  • Recommended chlorine exposure time at the defined conditions is 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.
  • Maximum cleaning temperature is 122°F (50°C) when chlorine is used.
  • Maximum cleaning temperature is 176°F (80°C) for cleaning cycles not involving chlorine.
  • Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide (H₂O₂) will accelerate membrane degradation.
• Cationic Polymers and Surfactants: MFK membranes may be irreversibly fouled if exposed to cationic (positively charged) polymers or surfactants. Exposure to these chemicals during operation or cleaning is not recommended and will void the warranty.
• 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.
