MQ PHT PES 50kDa

Summary

Product identification

Synder Filtration’s PHT Series of Ultrafiltration Elements are identified as PHT Sanitary Ultrafiltration Spiral-Wound Elements, model MQ (PES 50kDa).

Operating limits

• Maximum Temperature: 60°C (140°F)
• pH Range @ Max Temperature: 2-10
• 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 is 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: 2-12.5
• Chlorine:
  • Free Chlorine During Operation: 0 Norm ppm (<0.1 Max ppm)
  • Chlorine During CIP at pH 10.8-11.0 and 50°C: 150 Norm ppm (180 Max ppm)
  • Note: Maximum chlorine exposure for all elements is 30 minutes per day at pH and temperature conditions listed above.

Dairy Product Total Solids Limits

Maximum total solids percentages are provided for Sweet Whey, Acid Whey, Skim Milk, and Whole Milk, varying with the feed spacer size (31, 46, 65, 80 mils). See the official PDF for exact tabulated values. Trials are recommended to determine temperature and viscosity effects.

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, & fouling
• Customizable dimensions for unique housings

Common Applications

• Specialty protein separation
• Beverage clarification

Mechanical / hydraulic

The document lists various element models with their physical dimensions, weights, recommended cross-flow rates, and membrane areas.

• Element dimensions and weights:

  • Elements are available in various outer diameters (from 1.8 inches to 10.3 inches), lengths (from 12 inches to 50 inches), and permeate tube inner diameters (0.63, 0.75, 0.83, 1.14 inches).
  • Weights range from 0.5 kg (1.0 lb) for smaller elements up to 22.7 kg (50 lb) for larger models.
  • See the official PDF for exact tabulated values for specific models.
  • Note: Some models include 1" permeate tube extensions (0.75" OD).

• Recommended Element Cross Flow Rate:

  • Recommended cross flow rates are provided in m³/hr and gpm for various element diameters (1.8" to 10") across different feed spacer sizes (24, 31, 46, 65, 80 mils).
  • See the official PDF for exact tabulated values.

• Membrane Area:

  • Membrane areas are listed in square feet for different element models and feed spacer sizes (24, 31, 46, 65, 80 mils).
  • Areas range from 10 sq. ft. for smaller elements to 620 sq. ft. for larger models.
  • See the official PDF for exact tabulated values.
