EN3002 Wastewater Engineering

[Lecture: 26 hrs; Tutorial: 13 hrs; Lab: 0 hr; Pre-requisite: Year 3 standing; Academic Unit: 3]

Learning Objective :

This course aims to provide you with a basic understanding of the wastewater analysis/characterization, the preliminary design and operation of unit processes in wastewater treatment. You will acquire a deeper knowledge of the physical, chemical, and biological principles in wastewater assessment and treatment, with a particular emphasis on water recycle and resources recovery.

Course Content :

Characterization of wastewater. Analysis of wastewater flowrate and loading; Wastewater treatment: physical, chemical, and biological unit processes. Advanced wastewater treatment. Sludge treatment and disposal.




Physical, chemical and biological characteristics of wastewater


Analysis and selection of wastewater flowrates and constituent loadings for process design


Physical unit operations: Screening, grit chamber, sedimentation and air flotation


Chemical unit operations: coagulation, precipitation, chemical oxidation and scale control.


Biological treatment introduction, biomass growth kinetics


Advanced wastewater treatment: nutrient removal – Nitrogen and phosphorus removal, activated sludge processes and attached growth processes


Anaerobic treatment processes, sludge treatment and disposal: sources, characteristics and quantities of sludge. Treatment processes, gravity and flotation thickening, sludge digestion, vacuum and pressure filtration. Ultimate sludge disposal.

Learning Outcome :

By the end of the course, you would be able to:

  1. Analyse physical, chemical and biological characteristics of wastewater.
  2. Determine the design and operation of unit processes in wastewater treatment.
  3. Explore and develop sustainable wastewater treatment technologies.
  4. Conduct the system analysis toward optimal operations.
