Unit processes and operations for drinking water production are a dynamic research area in the program. The Program is especially well known for its strengths in the area of physical, chemical and biological treatment technologies for the purification of drinking water. Faculty in the Environmental Engineering Program study the control of carcinogenic organic byproducts of drinking water disinfection; factors which affect the formation of these byproducts; the media filtration and dissolved air flotation; removal of pathogens such as Cryptosporidium and Giardia; chemistry of coagulation; coagulation of natural organic matter in water; biologically-active filtration for drinking water purification; control of algae in water supplies; optimal design of dissolved air flotation; removal of manganese; and biological denitrification. An emerging research area is treatment processes for application in the developing world.
