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.

Instructor Bio:
scott-yaegerScott P. Yaeger has been an instructor in Microfiltration and Ultrafiltration Membranes for more than 10 years at American Filtration and Separation Society and American Institute of Chemical Engineering events. He has spent more than 30 years in the development, manufacturing and application of both microfiltration and ultrafiltration membranes for both dead end and tangential flow processes. His broad level of experience has helped him develop courses that not only teach the technical aspects but also the practical aspects of membrane filtration. Scott’s extensive knowledge for the application of these membranes in virtually all processes for a broad range of products can provide some unique insight in the maximizing membrane performance.

Mr. Yaeger has held senior level positions in R&D, Engineering, Manufacturing, Marketing, Sales and General Management in several multi-national membrane companies servicing the worldwide applications filtration products and services. He was the Founding Chairman of the American Filtration and Separation Society and has authored numerous articles in trade journals and international conferences. His courses are consistently rated as Very Good to Excellent.
