There are numerous contaminants in water that is to be used for drinking water. Filtration is the process of removing suspended solids from water by passing the water through a permeable fabric or porous bed of materials. Groundwater is naturally filtered as it flows through porous layers of soil. However, surface water and groundwater under the influence of surface water is subject to contamination from many sources. Some contaminants pose a threat to human health, and filtration is one of the oldest and simplest methods of removing them.
This 2-hour interactive online course presents the basics of filtration methods including slow and rapid sand filtration, diatomaceous earth filtration, direct filtration, packaged filtration, membrane filtration, and cartridge filtration. The material is taken from Technical Briefs published by the National Drinking Water Clearinghouse. The course is not intended to be a detailed design course, but rather provides an overview for each of these treatment methods.
This course includes a test at the end.
After completing this course, you will be able to:
• Describe how each of the different types of filtration systems remove contaminants in water used for drinking.
• Explain the advantages and limitations of each type of filtration system.
• List the expected removal efficiencies of each type of filtration system.
• Illustrate the process for selecting an appropriate filtration system.
