Overview
A membrane is a material capable of separating substances when a driving force is applied across the membrane. Relative to traditional potable water treatment processes that focus on liquid-solid separation, membranes are more effective at removing dissolved contaminants from source water. Thus, the popularity of membrane filtration has increased as drinking water standards have become more stringent. While membrane filters were once considered viable technology only for desalination, they are now increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material. As advancements are made in membrane technology, capital and operating costs continue to decline.
In this course the student will review the technical brief Membrane Filtration published by the National Drinking Water Clearinghouse. This course is particularly relevant to engineers involved in the design and selection of water treating and/or distribution systems, as well as engineers who are simply interested in learning more about potable water filtration systems.
The student must take a multiple-choice quiz consisting of ten questions at the end of this course to obtain PDH credits.
