CHE 446 Fundamentals of Industrial Wastewater Treatment
Credit Structure : (3-0)3
Catalog Description :
Introduction to waste treatment in industrial plants. Kinetics of
reactions involved in different methods. Chemical study of unit processes and
unit operations. Design of treatment devices for purification
of wastewater and control procedures for environmental protection.
Course Objectives:
To give the students basic
principles for the processes used to treat various types of wastewaters and
design procedures with calculations mainly for different biological treatment
schemes; abilities to communicate effectively and function effectively within
teams; a solid understanding of professional and ethical responsibility; an
awareness of the need for, and ability to engage life-long learning; an understanding
of the impact of chemical engineering in a global and environmental context,
consistent with the principles of sustainable development; a familiarity with
the contemporary chemical engineering issues.
