This first lecture on Beer Filtration focuses on the theory of filtration and particularly the mechanisms by which beer (or wort) are filtered.

Many of these filters operate primarily on the basis of filter aids such as diatomaceous earth. Filter Aids' characteristics can impact beer quality and process throughput.

Learning Objectives

  • Describe the different mechanisms of filtration
  • Describe the main differences between surface and depth filters
  • Explain the main types of filter aids
