Elements for the design and management of the main waste treatment and disposal technologies for energy recovery.
Course Prerequisites
Knowledge of chemistry, Sanitary-Environmental engineering, and plant design
Teaching Methods
The course is organized into lessons and exercises.
Assessment Methods
Method: written test Evaluation parameters: ability to discursively organize knowledge. The questions will focus on both the theory part and the exercise part with also the request for numerical resolutions. Number and types of tests that contribute to the final evaluation: written test.
