BN PHT PVDF 50kDa

Summary

Product identification

The PHT Series Ultrafiltration Elements are made with PVDF (polyvinylidene fluoride) and have a 50 kDa (kilodalton) molecular weight cut-off. They are spiral-wound elements designed for sanitary applications.

PHT Series Benefits:

• Conforms to 3-A, FDA, and USDA sanitary standards
• Elimination of chlorine during CIP with hot sanitation
• High resistance to pH, temperature, and fouling
• Customizable dimensions for unique housings

Common Applications:

• Brine clarification
• Protein concentration

Operating limits

Operating Parameters:

• Maximum Temperature: 60°C (140°F)
• pH Range @ Max Temperature: 3-10
• pH Range @ Ambient Temperature: 2-10.5

Pressure:

• Max Inlet Pressure: 120 PSI (8.3 Bar)
• Min Outlet Pressure: 10 PSI (0.7 Bar)
• Max Differential Pressure per Element: 18 PSI (1.2 Bar)
• Max Permeate Backpressure: 5 PSI (0.3 Bar)
• Note: Soft start on boost pumps required to minimize pressure/flow shocks to elements.

Cleaning Parameters:

• Maximum Temperature (Short term <30min): 85°C (185°F)
• pH Range @ Max Temperature: 2-11
• pH Range @ Ambient Temperature: 2-12

Chlorine:

• Free Chlorine During Operation:
  • Norm ppm: 0
  • Max ppm: <0.1
• Chlorine During CIP at pH 10.8-11.0 and 50°C:
  • Norm ppm: 150
  • Max ppm: 180
• Note: Maximum chlorine exposure for all elements is 30 minutes per day at pH and temperature conditions listed above.

Feed water

Dairy Product Total Solids Limits:

• Note: Trials should be made to determine temperature and viscosity effects.

Mechanical / hydraulic

A wide range of element models are available with varying diameters, lengths, permeate water tube IDs, weights, recommended cross flow rates, and membrane areas.

For exact tabulated values for specific models (e.g., 1812F, 2519, 3838, etc.) including:

• Outer Diameter (OD), Length (L), Permeate Water Tube Inner Diameter (P.W.T. ID or ID*)
• Weight (lb and kg)
• Recommended Element Cross Flow Rate (m³/hr and gpm) for various feed spacer sizes (24, 31, 46, 65, 80 mils)
• Membrane Area (sq. ft.) for various feed spacer sizes (24, 31, 46, 65, 80 mils) See the official PDF for exact tabulated values.

Notes:

• *1” permeate tube extensions (0.75” OD) are available for certain models.
• Different diameters are available; requirements should be specified when ordering.
• Elements can be designed to fit exact needs by specifying element outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length.
• Elements are available with or without a controlled bypass tail.
• Additional feed spacers are available.
• The recommended cross flow rate is subject to differential pressure limitations and specific applications.
• Trials should be conducted to determine optimal application conditions.
