History, Mechanisms, and Classifications of Filters

1.0 Credit


This course provides students with a basic understanding of water filtration mechanisms, concepts, equations and the various methods of classifying filtration systems. Topics include a historical overview of the development of water treatment in Europe and North America and its impacts on water filtration today. In addition, the mechanisms governing filtration are covered along with concepts in fluid dynamics and the equations used. Finally, the media properties, filtration classifications and river, slow sand and precoat or cake filtration are discussed.

Delivery Method



Industry experience or completion of level two portion of the Water Treatment Technology program.


After successfully completing this course, students should be able to:

  • Outline the development of water filtration throughout Europe and North America and how these early concepts influenced water treatment today.
  • Explain basic filtration mechanisms some basic concepts in fluid mechanics and filtration equations.
  • Describe basic media properties and the major filter classifications.
  • Explain how river, slow sand, and pre-coat or cake filtration works.
