WATER TREATMENT - 2019/0

Module Overview

This module is one of the core subjects which provides students with essential knowledge of drinking water treatment and supply. In this module students learn about conventional and advanced water treatment methods and related design principles. The lectures of this module are delivered by academics and water industry experts. On successful completion of the module, the students are able to show originality in the application of knowledge of water treatment to specific situations. The primary JBM threads for this module include: Design, Sustainability and Health and Safety Risk Management; and this module covers Professionalism and Ethics as contributory thread.

Module content

Indicative content includes:

• Defining the needs of water treatment – EC directives/WHO guidelines /other international regulations;


• Environmental and water quality management of reservoirs, raw water sources;


• Rationale behind water treatment process design- Multiple barrier approach;


• Review of water treatment processes applicable for the industrialised & developing world;


• Unit processes and design guidelines of removing contaminants, including coagulation, sedimentation, softening, disinfection, rapid gravity filtration, membrane filtration, adsorption, gravel upflow/downflow filters, and slow sand filtration;


• Water treatment in unusual circumstances, oxidation processes and desalination with reverse osmosis (RO);


• Water supply issues and distribution network;


• Operational management of water treatment and auditing technical performance.

Assessment pattern

Alternative Assessment

None.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

• Critical awareness of the rationale behind water treatment and the analysis of the design principles in drinking water treatment and supply (LO’s 1, 2 and 4) is assessed through both coursework and 2 hour unseen examination.


• Appropriate selection of water treatment processes and the evaluation of industrial and professional practices on water treatment plant operation and management (LO’s 3, 4, 5 and 6).  This is assessed through the water treatment plant design coursework.


• Evaluation of problems in water treatment and distribution, both in industrialised and developing world, for most appropriate treatment process selection and management strategies (LO’s 4, 5 and 6). This is assessed through both coursework and 2 hour unseen examination.

• Examination [Learning outcomes assessed 1, 2, 3, 4 and 6] (2 hours) {70%}


• Coursework on i). Water treatment process principles and design, and ii). Water supply/distribution [Learning outcomes assessed 1, 2, 3, 4, 5 and 6] (37 hours) {30%}

• Formative assessment will be through a range of exercises provided in the lecture notes and discussed in the classroom. In particular, one quiz will be used to provide the formative feedback.


• Students will receive written feedback on the quiz, and verbal feedback will be provided in the classroom.

Module aims

• Provide a systematic understanding and critical awareness of the issues involved in producing potable water in both the industrialised and developing world
• Provide insights from edge of field on managing drinking water sources such as lakes and reservoirs
• Provide a systematic understanding of water treatment and supply systems including abstraction, storage and distribution and physico-chemical unit processes
• Provide a comprehensive understanding of water treatment process design and management
• Provide a systematic understanding and critical awareness of the particular issues in designing and operating treatment systems in the developing world

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

This module provides basic and applied knowledge that is required to serve the drinking water supply industry and water quality agencies. The knowledge gained in this module, related to, coagulation-flocculation-sedimentation units, softening units and other unit operations, is commonly required in quality assurance and operation of drinking water supply. Industry experts from UK and Germany also deliver lectures to provide industry relevant practical knowledge.

The learning and teaching activities include lectures, classroom exercises and design coursework:

• Lecture on water sources and quality (3 hours)


• Lectures and classroom exercises on water treatment processes and design of process units (15 hours)


• Lecture on water supply and distribution (3 hours)


• Lecture on water supply in developing countries (3 hours)


• Lecture on ground water quality contaminants (3 hours)


• Lecture on reservoir water quality (3 hours)


• Lecture on water treatment and supply practices in Germany (3 hours)


• Coursework on design of water treatment processes and plant (37 hours)


• Independent study on water treatment, design and supply (80 hours)

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
