| Module Overview |
| This is a compulsory module to provide students essential knowledge of water chemistry, microbiology and chemical processes associated with water and wastewater treatment. On successful completion of the module, the students are able to apply the above knowledge in the practice of water and wastewater treatment and other environmental engineering applications. |
|
|
| Prerequisites/Co-requisites |
A basic knowledge of chemistry and biology. |
|
|
| Module Aims |
To provide a systematic understanding and critical awareness of the water chemistry, microbiology and chemical processes associated with water and wastewater treatment. |
|
|
| Learning Outcomes |
Upon successful completion of the module, students should be able to:
- Demonstrate a comprehensive understanding of the underlying biological, physical and chemical science principles and governing equations applicable to water and wastewater treatment;
- Understand the relevant chemical process principles as applied to the treatment of water and wastewater;
- Apply the above knowledge in the practice of water and wastewater treatment and other environmental engineering applications.

| Module Content |
· Aqueous chemistry, including moles, equivalents, and other units and definitions, solubility product constant, the behaviour of acids and bases and the concept of pH, water hardness and alkalinity, kinetics and equilibria, and electrochemistry;
· Process principles including fluid mixing, mass balance and mass transfer;
· Microbiology and biochemistry with reference to classification and terminology, the role of enzymes in metabolism, and biochemical pathways of special interest to water and wastewater processes;
Practical Content: There will be 9-hours’ laboratory classes introducing experimental skills including measurements of chlorine demands and residuals and microbiology tests. |
