Microfiltration Membrane

Course: 0.4 CEUs,
Scott Yaeger, Instructor

Learn in-depth knowledge of the various types of microporous membranes including: Strengths and Weaknesses, Performance Characteristics, Integrity Testing, Retention Efficiency, Ratings and Comparisons. Learn to differentiate between microporous, ultrafiltration, nanofiltration, and reverse osmosis membranes.

The attendee will learn about membrane:

  • Definitions: Microfiltration, Ultrafiltration, Nanofiltration, and Reverse Osmosis
  • Types: Philicity, Morphology, Structure, Formats, Materials, and Supports
  • Membrane Formation: Liquid, Gas, and Thermal Phase Inversion, Stretching, Substitution, Etching
  • Pore Structure: Isotropic, Anisotropic, Duel Anisotropic, Asymmetric
  • Pore Size: History, Measurement, Efficiency, Reality, Integrity Testing, Distribution
  • Retention Efficiency: Nominal, Absolute, LRV, Sterilizing Grade, Nominally Absolute, or Absolutely Nominal
  • Surface Modification: Philicity, Zeta Potential, Ion Exchange, Affinity, Adsorption
  • Retention Mechanisms: Sieve, Depth, Adsorption, Impingement,
  • Pressure/Flow Characteristics: Thickness, Pore Distribution, Surface Area, Effective Surface Area
  • Life: Plugging, Passage, Grow Through
  • Device Geometries: Pleated, Pleat Variations, Hollow Fiber, Tubular, Spiral Wound, Flat Plate Cassettes
  • Applications: Pharmaceutical, BioPharmaceutical, Food and Beverage, Microelectronics, Chemical, Medical, Laboratory

The aforementioned bullet points are representative but by no means totally inclusive.
