BX PHT PVDF 250kDa

Summary

Product Identification

Synder Filtration's PHT Series Ultrafiltration Elements are spiral-wound, sanitary-grade membranes. This specific product is a BX (PVDF 250kDa) membrane, indicating a Polyvinylidene Fluoride (PVDF) membrane with a molecular weight cut-off (MWCO) of 250 kDa. These elements are designed for exceptional physical and chemical durability.

Operating Limits

• 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 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

Chlorine Exposure

• 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 the pH and temperature conditions listed above.

Dairy Product Total Solids Limits

Maximum total solids (T.S.) limits for various dairy products based on feed spacer size:

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

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

• Corn wet milling
• Microbial/Particle removal

Mechanical / Hydraulic

Element Dimensions and Weight Elements are available in various model numbers with different diameters, lengths, permeate tube IDs, and weights.

• Columns: Model No., OD (in.), L (in.), ID* (in.), Weight (lb), Weight (kg)
• For example, the 1812F model has an OD of 1.8 in, length of 12 in, ID of 0.63 in, and weighs 1.0 lb (0.5 kg).
• The 2540M model has 1" permeate tube extensions (0.75" OD).
• Note: Different diameters are available. Specifications are subject to change without notice.
• See the official PDF for exact tabulated values for all models.

Recommended Element Cross Flow Rate Cross flow rates vary significantly based on element diameter and feed spacer size.

• Columns: Element (diameter), Feed Spacer (mils), m³/hr, gpm
• For example, a 1.8" element with a 31 mil feed spacer has a recommended cross flow rate of 1 m³/hr (5 gpm).
• Note: The recommended cross flow rate will be subject to differential pressure limitations and specific applications. Please consult Synder Filtration if additional information is needed.
• See the official PDF for exact tabulated values for all models and feed spacer combinations.

Membrane Area (sq. ft.) Membrane area varies based on the element model and feed spacer size.

• Columns: Element Model No., Feed Spacer (mils), then membrane area in sq. ft.
• For example, a 2540F element with a 31 mil feed spacer has a membrane area of 29 sq. ft.
• Note: Not all feed spacer options are available for every element model, as indicated by 'N/A'.
• See the official PDF for exact tabulated values for all models and feed spacer combinations.

Technical Notes: For element sizes not listed, Synder Filtration can custom design elements to specific needs (outer diameter, vessel/housing inner diameter, element inner diameter, and length). Elements are also available with or without a controlled bypass tail, and additional feed spacers are available. Trials are recommended to determine optimal application conditions.
