Overview
The purpose of water treatment is to do whatever is necessary to render a raw water suitable for its intended use. Depending on the quality of the water source and the intended use, treatment may range from simple disinfection with chlorine to more expensive, specialized processes such as reverse osmosis or ion exchange treatment. This course examines the more common water treatment problems and addresses the most likely means of treatment. Emphasis is placed on identifying the base available technologies (BAT) for treating small water systems, although much of the material is also applicable to large water systems.
In this course the student will review Chapter 6, "Water Treatment" of EM 1110-2-503, "Design of Small Water Systems" published by the U.S. Army Corps of Engineers. This course is particularly relevant to engineers involved in designing both public and private water systems. Although the publication's title suggests coverage of only small water systems, much of the discussion applies to large systems as well.
The student must take a multiple-choice quiz consisting of fifteen questions at the end of this course to obtain PDH credits.
