HpHT 3838-K131-NYV

Summary

Product Identification

The KMS HpHT™ HFK™131 series consists of FOOD & DAIRY Ultrafiltration (UF) ELEMENTS designed for high pH and temperature cleaning.

• Membrane Chemistry: Proprietary semi-permeable polyethersulfone (PES)
• Membrane Type: HpHT™ HFK™-131, with an observed separation range of 10,000 Daltons. The membrane layer is PES on a polyolefin backing material.
• Construction: Sanitary spiral wound with net outer wrap
• Regulatory Status: Conforms to USDA 3-A standards and FDA regulations (CFR Title 21)
• Standard Options:
  • Diameter: 3.8, 4.3, 6.4, and 8.0 inches
  • Length: 36 or 38 inches
  • Feed Spacer: N (31 mil), V (46 mil), H (62 mil), or F (80 mil)
  • Outer Wrap: Controlled (e.g., NYV) or trimmable (e.g., NYT)
• Pure Water Flux: 1.0-2.2 gfd/psi (24-53 l/m²/h/bar) at 77°F (25°C).

Specifications

Operating Limits

• Typical Operating Pressure: 30 - 120 psi (2.1 - 8.3 bar)
• Maximum Operating Pressure: 140 psi (9.7 bar)
• Operating Temperature Range: 41 - 140°F (5 - 60°C)
• Cleaning Temperature Range: 105 - 185°F (40 - 85°C)
• Allowable pH - Continuous Operation: 2.0 - 10.0
• Allowable pH - Clean-In-Place (CIP): 1.8 – 12.5
• Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time (including online, off-line, and during transition). Reverse pressure will damage the membrane.
• Design Pressure Drop (below 140°F / 60°C):
  • 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)
  • Per Vessel (3 elements 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)
  • Per Vessel (4 elements in series):
    • N spacer: 48-60 psi (3.3-4.1 bar)
    • V spacer: 60-68 psi (4.1-4.7 bar)
• Maximum Pressure Drop (above 140°F / 60°C):
  • 10 psi (0.7 bar) per element for N and V spacers
  • 15 psi (1.0 bar) per element for H and F spacers

Feed Water

• Maximum Feed Turbidity: 1 NTU
• Maximum Feed SDI: 5.0 (15-minute test)
• Chemical Exposure - Oxidizing Agents:
  • Exposure of HpHT membrane to free chlorine or other oxidizing agents such as permanganate, ozone, bromine, and iodine is not recommended.
  • Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide will accelerate membrane degradation.
• Chemical Exposure - Cationic Polymers and Surfactants:
  • PES 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.

Mechanical / Hydraulic

Nominal Dimensions

• Lubricants for Installation: For module installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the module and will void the warranty.
