PHILOSOPHY:
The course imparts to students the technical underpinnings to develop solutions for the environmental challenges faced by engineers today and provide insight into ways of tackling the emerging issues. The course covers the physical and chemical properties of environmental pollutants, the fate of pollutants in the environment and the principles of various treatment processes. The interdisciplinary knowledge gained in this course will provide attendees with a solid foundation for designing unit processes and making informed decisions as practicing environmental engineers.
ASSESSMENT:
For this 15-point course (100 marks):
· 40 marks are allocated to course work
o three online quizzes (18 marks)
o two lab reports (18 marks)
o student’s participation, basically attendance (4 marks).
· 20 marks to one mid-term test
· 40 marks to final exam (* a student must PASS the final exam to pass the course)
LEARNING OBJECTIVES:
This course aims to further equip you with a broad spectrum of environmental engineering related knowledge, and to advance your capability of applying fundamental mathematical, physical, chemical, and microbiological principles to solve a range of environmental issues. On the completion of this course, students will be able to:
- Identify the underlying mechanism(s) of environmental impact from various pollutants.
- Break down environmental systems into their respective key components to analyse them for specific engineering design purpose.
- Discuss the principles of various treatment processes.
- Predict quantitatively any impacts of different engineering parameters on the efficacy of an environmental treatment process.
- Apply fundamental principles to gain an understanding of behaviours of different environmental pollutants.
- Understand basic water chemistry and develop a preliminary assessment of the fate of contaminants in the aquatic environment.

LABORATORY:
LAB 01: Metal complexation in wastewaters (NS)
LAB 02: Chemical transport in soils (AS)
All experiments will be conducted in the Environmental Engineering Laboratory (201B) at the time specified in the laboratory schedule distributed during class. All students must attend labs and submit a report for each experiment conducted in the laboratory.
Safety note: students must wear closed-toed shoes (i.e. no sandals or similar footwear). Students will be asked to leave if wearing inappropriate shoes.
