Small Water Systems - Water
Treatment
Edward Brunet, Jr., P.E.
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.
