Slow and Rapid Sand Filtration

1.0 Credit

Description

With proper pre-treatment of the water, slow and rapid sand filters are applicable for treatment of any surface supply. Such filters are effective even for highly polluted waters. Even relatively large variations in bacterial pollution loads can be handled in a well-designed and well-operated sand media water plant. This course covers in detail, the process of slow and rapid sand filtration as introduced in Basic Principles of Sedimentation and Filtration. Topics include filter operation, performance optimization, maintenance and backwashing techniques.

Delivery Method

Web-based.

Prerequisites

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

Objectives

By the end of this course, students should be able to:

  • Investigate and identify the components used in slow sand filtration.
  • Investigate the different removal mechanisms available in a slow sand filter.
  • Investigate the different removal mechanisms available in a slow sand filter.
  • Investigate the different parameters that affect slow sand filter performance.
  • Investigate and identify the components used in rapid sand filtration.
  • Investigate the different removal mechanisms available in a rapid sand filter.
  • Investigate the performance parameters associated with a rapid sand filter.
  • Investigate and understand the backwashing process used on a rapid sand filter.
