Summary
Product Identification
This document describes a Sanitary Ultrafiltration (UF) Spiral-Wound Element, specifically the BY (PVDF 100kDa) model from Synder Filtration. These Ultrafiltration Elements are designed to offer an optimal combination of flux and rejection across a comprehensive range of molecular weight cut-offs (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
- Maximum Inlet Pressure: 120 PSI (8.3 Bar)
- Minimum Outlet Pressure: 10 PSI (0.7 Bar)
- Maximum Differential Pressure per Element: 18 PSI (1.2 Bar)
- Maximum 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 <30 min): 50°C (122°F)
- pH Range @ Max Temperature: 2-11
- pH Range @ Ambient Temperature: 1.8-11
- Free Chlorine During Operation:
- Normal: 0 ppm
- Maximum: <0.1 ppm
- Chlorine During CIP (at pH 10.8-11.0 and 50°C):
- Normal: 150 ppm
- Maximum: 180 ppm
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: The datasheet provides a table for maximum total solids (T.S.) for various dairy products (Sweet Whey, Acid Whey, Skim Milk, Whole Milk) based on feed spacer thickness (31, 46, 65, 80 mils). See the official PDF for exact tabulated values. Note: Trials should be made to determine temperature and viscosity effects.

*Models 2540M and 3938.75 (footnote from Element Dimensions table) and models marked with * in Element Descriptions table: 1” permeate tube extensions (0.75” OD).
Membrane Area (SQ. FT.): The membrane area varies significantly based on the model number and the feed spacer thickness (24, 31, 46, 65, 80 mils). See the official PDF for exact tabulated values.
Recommended Element Cross Flow Rate: Recommended cross flow rates (in m³/hr and gpm) are provided for various element sizes and feed spacer thicknesses. See the official PDF for exact tabulated values. Note: The recommended cross flow rate will be subject to differential pressure limitations and specific applications.
