CVEN40070 Water & Wastewater Treatment Processes

Academic Year 2023/2024

This elective course is designed primarily for civil engineering students to provide them with the fundamental knowledge required in the water treatment and wastewater treatment sectors. The course is divided into 4 thematic areas: applied water chemistry and microbiology; water analysis; drinking water production processes; and wastewater treatment processes. Among the topics addressed are: principles of chemistry and microbiology specifically invoked in the engineering control of water quality; routine analytical methods associated with water production and wastewater treatment; coagulation; flocculation; clarification (sedimentation and flotation); filtration, chemical stabilisation, and disinfection; preliminary treatment; primary treatment; secondary treatment (activated sludge and biofiltration); sludge treatment; and relationships between effluent and environmental standards.

Learning Outcomes:

Upon completion of this course, students should be able to:
1. Develop, from first principles, the basic equations describing the physics, chemistry and microbiology of water and wastewater treatment processes.
2. Apply these equations to solve problems relating to the design of water and wastewater treatment infrastructure, appreciating the underlying assumptions and limitations.
3. Demonstrate understanding of the physical, chemical and microbiological fundamentals of water and wastewater treatment, and their relevance vis-a-vis water quality.
4. Demonstrate the ability to communicate effectively on technical issues related to water and wastewater analyses.
