• Note: Maximum chlorine exposure for all elements is 30 minutes per day at pH and temperature conditions listed above.

Mechanical / hydraulic

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 required to minimize pressure/flow shocks to elements.

Element Dimensions: Element dimensions, including Diameter (OD), Length (L), and Permeate Water Tube Inner Diameter (P.W.T. ID), vary significantly by model number. Element weights are also provided in the datasheet. See the official PDF for exact tabulated values for each model.

Membrane Area: The membrane area (in sq. ft.) varies depending on the element model number and feed spacer thickness (in mils). See the official PDF for exact tabulated values.

Recommended Element Cross Flow Rate: Recommended cross flow rates (in m³/hr and gpm) vary depending on the element and feed spacer thickness (in mils). The recommended cross flow rate will be subject to differential pressure limitations and specific applications. See the official PDF for exact tabulated values.

Feed water

Dairy Product Total Solids Limits: Maximum total solids (T.S.) for dairy products vary based on the feed spacer thickness (in mils).

• Sweet Whey Max. T.S.: 15 - 30 (depending on feed spacer)
• Acid Whey Max. T.S.: 15 - 28 (depending on feed spacer)
• Skim Milk Max. T.S.: 14 - 28 (depending on feed spacer)
• Whole Milk Max. T.S.: 15 - 35 (depending on feed spacer)
• Note: Trials should be made to determine temperature and viscosity effects.
