ET 1244 - Chemical Treatment

Course Description

Most water and wastewater treatment plants now use chemicals for some of the processes. In water treatment, chemicals are used to adjust pH, aid in settling particulate matter, to enhance filtration, and to remove trace constituents. In wastewater treatment, chemicals can be used to remove phosphorus; they can enhance settling in primary and/or biological treatment; they can assist in odor control, sludge thickening, sludge dewatering, and sludge stabilization. In this class, students will learn about the various chemicals used, how they can be stored and handled safely, and how to calculate dosages. Ideas on costs and how to contract for the purchase of chemicals will be provided.
