Benefits of this standard series include:

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

Common applications for this element include:

• Specialty protein separation
• Beverage clarification

Operating limits

• Maximum Temperature: 55°C (131°F)
• pH Range @ Max Temperature: 3-9
• pH Range @ Ambient Temperature: 2-10

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.

• pH Range @ Ambient Temperature: 1.8-11

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.

Feed water

Dairy Product Total Solids Limits

Maximum total solids for various dairy products are dependent on the feed spacer size. Trials should be conducted to determine temperature and viscosity effects.

• Sweet Whey Max. T.S.: 15 (31 mil), 25 (46 mil), 28 (65 mil), 30 (80 mil)
• Acid Whey Max. T.S.: 15 (31 mil), 24 (46 mil), 26 (65 mil), 28 (80 mil)
• Skim Milk Max. T.S.: 14 (31 mil), 24 (46 mil), 26 (65 mil), 28 (80 mil)
• Whole Milk Max. T.S.: 15 (31 mil), 30 (46 mil), 33 (65 mil), 35 (80 mil)

Mechanical / hydraulic

The element dimensions, membrane area, and recommended cross flow rates vary significantly by model number and feed spacer size.

• Element Dimensions: A comprehensive table lists Element Model No., Diameter (B) in, Length (A) in, and P.W.T. ID (Permeate Water Tube Inner Diameter). For example, model 1812F has a diameter of 1.8 in, length of 12 in, and P.W.T. ID of 0.63 in. Other models range up to 10.3 in diameter and 50 in length. Note: 2540M and *1" permeate tube extensions have 0.75" OD.
• Membrane Area: This is provided in square feet (sq. ft.) for each element model across various feed spacer sizes (24, 31, 46, 65, 80 mils). Values range from 3.6 sq. ft. for the 1812F (31 mil spacer) to 620 sq. ft. for the 10338 (31 mil spacer). Some combinations are marked N/A.
• Recommended Element Cross Flow Rate: Provided in m³/hr and gpm for elements grouped by approximate diameter, and across different feed spacer sizes (24, 31, 46, 65, 80 mils). For example, 1.8" diameter elements range from 1-2 m³/hr (4-7 gpm) depending on the spacer. The largest 10" diameter elements range from 42-68 m³/hr (184-299 gpm). The recommended cross flow rate is subject to differential pressure limitations and specific applications.
• Element Descriptions (Weight): A table provides Model No., OD (in.), L (in.), ID* (in.), Weight (lb), and Weight (kg) for various elements. For example, the 1812F weighs 1.0 lb (0.5 kg), while the 10338 weighs 50 lb (22.7 kg).
