AIMS

This module aims to provide a basic knowledge of classical and contemporary problems in the management of wastewater for the practising engineer. It provides a basic knowledge of the main physical, chemical and biological processes used for the treatment of wastewater. It offers gaining practical experience in selecting the appropriate wastewater collection and treatment schemes, and in designing the required works.

INTENDED LEARNING OUTCOMES

1. Subject Specific Knowledge, Understanding and Skills

By the end of this module, the students should:

• have acquired an understanding of waste water collection system components, their characteristics and functioning of such systems;
• be able to design a wastewater collection system;
• be able to estimate or measure the pollution load of wastewater produced in an area or from a particular activity;
• have acquired a basic understanding of unit treatment processes;
• understand the role, the kinetics and the factors affecting the performance of microorganisms in a particular biological treatment process;
• be able to design treatment units;
• recognize the environmental impact of wastewater discharge to the environment.

2. Core Academic Skills

By the end of this module, the students should:

• be able to identify, formulate and analyse a management problem in a given water collection/treatment system, i.e. assess the situation, formulate alternatives and recommend feasible solutions;
• be able to critically assess research results;
• have acquired some practical experience of using wastewater collection and treatment modelling tools;
• have acquired an understanding of the impact of solutions for civil engineering works.

3. Personal and Key Skills

By the end of this module, the students should have:

• improved further the necessary skills for independent learning;
• enhanced report and presentation skills;
• acquired an ability to function in multi-national teams.
