Wastewater Engineering
Module Notes
Module Details
Ability to apply biochemical engineering principles to wastewater treatment processes
Ability to formulate mathematical models able to describe physicochemical and/or biological processes pertaining to either municipal or industrial wastewater treatment
Knowledge of physicochemical (conventional/advanced oxidation) and biological processes and their application in wastewater treatment plants
Ability to design and assess both chemical (including advanced oxidation) as well as biological processes for municipal and industrial wastewater treatment systems
There are no prerequisites for this module. However, students should have basic knowledge of mass and energy balances, unit operations and biochemical processes.
Wastewater flowrates. Qualitative and quantitative characteristics of wastewaters. Sewage networks. Legislation and treatment levels. Pretreatment (screens, grit chambers, grease removal, flow stabilization). Primary sedimentation and flotation. Fundamentals of microbiology and microbial kinetics. Secondary treatment. The activated sludge process. Alternative secondary suspended growth systems. Biofilm systems (trickling filters and biodiscs). Nutrient removal (nitrification, denitrification, biological phosphorus removal). Modelling of activated sludge systems. Natural systems for wastewater treatment. Disinfection. Sludge (biosolids) management.
Sources and characteristics of industrial effluents. Methods of evaluation of the polluting loading. Physical and chemical treatment technologies:
- Coagulation - flocculation

Advanced oxidation processes (AOPs)
- Ozone oxidation
- Photocatalysis
- Electrochemical processes
- Ultrasound irradiation
- Thermochemical processes
Process integration
