CEG8104 : Wastewater Engineering

Semester 1 Credit Value: 5
Semester 2 Credit Value: 5
ECTS Credits: 5.0


This module is designed to provide a basic understanding of the design and operation of unit processes in the treatment of domestic and industrial wastewaters, with a particular emphasis on biological principles and parameters. An introduction to recent developments and more advanced techniques in biological wastewater treatment will be provided. Students also develop a deeper knowledge of the physical, chemical and biological principles in wastewater assessment and treatment. Basic analytical and the latest molecular microbial ecology skills will be developed through laboratory analysis of wastewater and sludge samples.

Teaching Rationale And Relationship

Knowledge and understanding are acquired primarily through the lecture classes, tutorials and laboratory practicals, with students expected to undertake self-directed learning by reading of technical journal papers, text books, legislation and the selective use of web sites. Laboratory (practical) classes provide a deeper understanding of the practical aspects of the unit processes, they also provide skills and experience that supports the design coursework of other modules, and how wastewater treatment plants achieve compliance to statutory regulations.
*Alternatives will be offered for students who are unable to attend the tutorials/practicals in person.
**Timetabled activities, alternatives will be offered for students who are unable to attend at the specified time.

Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

A design report/presentation is considered the most appropriate and efficient method to assess the range of Knowledge Outcomes in particular, but also includes assessment of the Skills Outcomes.

The laboratory report assesses the understanding of the practical elements of the module, as well as addressing the knowledge and practical skills outcomes.
