Summary

Product identification

This is a Sanitary Ultrafiltration Spiral-Wound Element, model ST (PES 10kDa). These ultrafiltration elements offer an optimal combination of flux and rejection across a comprehensive range of MWCOs.

Standard Series Benefits:

• Conforms to 3-A, FDA, and USDA sanitary standards
• Widest range of UF MWCOs available
• Good resistance to pH and temperature
• High resistance to fouling
• Customizable dimensions for unique housings

Operating limits

• Maximum Temperature: 55°C (131°F)
• pH Range @ Max Temperature: 3-9
• pH Range @ Ambient Temperature: 2-10
• 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): 50°C (122°F)
• pH Range @ Max Temperature: 2-11
• pH Range @ Ambient Temperature: 1.8-11
• 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 the pH and temperature conditions listed above.

Feed water

Dairy Product Total Solids Limits (Max. T.S.) The maximum total solids for dairy products vary by feed spacer size (in mils):

• Sweet Whey: 15 (31 mil), 25 (46 mil), 28 (65 mil), 30 (80 mil)
• Acid Whey: 15 (31 mil), 24 (46 mil), 26 (65 mil), 28 (80 mil)
• Skim Milk: 14 (31 mil), 24 (46 mil), 26 (65 mil), 28 (80 mil)
• Whole Milk: 15 (31 mil), 30 (46 mil), 33 (65 mil), 35 (80 mil)
• Note: Trials should be made to determine temperature and viscosity effects.

Mechanical / hydraulic

Synder Filtration offers a range of element models with varying dimensions, membrane areas, and recommended cross-flow rates depending on the model number and feed spacer configuration.

Element Dimensions and Weight: Elements are available in various Outer Diameters (OD), Lengths (L), Permeate Water Tube Inner Diameters (P.W.T. ID), and weights. For example, common ODs range from 1.8" to 10.3", lengths from 12" to 50", and P.W.T. IDs from 0.63" to 1.14". Weights vary from 0.5 kg to 22.7 kg.

• See the official PDF for exact tabulated values for each model's OD, Length, ID, and Weight.
• Note: Some models like 2540M have 1" permeate tube extensions (0.75" OD).

Membrane Area (SQ. FT.): Membrane area varies significantly by element model number and selected feed spacer thickness (e.g., 24, 31, 46, 65, 80 mils).

• See the official PDF for exact tabulated values of membrane area per model and feed spacer.

Recommended Element Cross Flow Rate: Recommended cross flow rates vary by element diameter and feed spacer thickness. For example, a 1.8" element might have cross-flow rates from 1-2 m³/hr (4-7 gpm), while a 10" element could have rates from 42-68 m³/hr (184-299 gpm).

• See the official PDF for exact tabulated values of recommended cross flow rates per element and feed spacer.
• Note: The recommended cross flow rate will be subject to differential pressure limitations and specific applications.

Common applications

• Whey protein concentrate & isolate production
• Gelatin concentration
• Beverage clarification
• Enzyme concentration
