CEG2101 : Treatment of Water and Wastewater

Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

1. To introduce and discuss the fundamental processes underpinning the design of water and wastewater treatment processes.
2. To introduce and discuss the various components of water and wastewater treatment plants.
3. To exercise the design and analysis of some unit processes used in water and wastewater treatment.

The treatment of water and wastewater relies on biological and physicochemical unit processes to remove pathogens, nutrients, biological oxygen demand or pollutants from water. To meet drinking water quality and wastewater effluent standards engineers need to be able to properly design treatment processes based on their understanding of the underlying scientific principles. This module will provide an overview of the unit processes used in water and wastewater treatment and will exemplify the detailed design for one unit process.

Outline Of Syllabus

The module will provide a schematic overview of the unit processes used in a drinking water and wastewater treatment plant. Drinking water and effluent standards will be covered. Low tech and high tech systems will be compared. The basic scientific principles for the engineering design will be introduced. The module will illustrate the detailed design of one unit process, the removal of trace chemical pollutants from drinking water with activated carbon using data measured in the practical.

Teaching Rationale And Relationship

Learning outcomes will be achieved by introducing knowledge and theory in lectures and by exercising the relevant skills in practicals and design workshops. Design workshops will simultaneously review the taught content of some lectures and develop the key intellectual or communication skills. The group learning exercises will train independent learning, design and team work skills. The student’s broader knowledge of the subject area will be assessed with a written exam.

Assessment Methods

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