Aims

This module is designed to provide a conceptual understanding of the legal, health and technical aspects of treating water for drinking and industrial purposes, and to introduce the principles involved in the design and selection of unit processes for a water treatment plant.

Teaching Rationale And Relationship

Knowledge and understanding are acquired primarily through lecture classes. However, students are expected to add to this by directed reading of technical journal papers, text books and selective use of web sites. Laboratory (practical) classes provide deeper understanding of practical aspects of unit processes and they also provide skills and experience that support the design coursework in module CEG8108. Data analysis and tutorials to help to formulate numeracy and design skills. The field trip is included to provide practical context for lecture materials.

Assessment Rationale And Relationship

The coursework (Laboratory Report) will assess both the Knowledge Outcomes and Skills Outcomes, by providing students with the technical challenge of practising key water treatment unit processes at laboratory-scale, analysing key physical, chemical and biological parameters in treated water, and using the data generated to prove fundamental assumptions behind the water treatment process. The written report will provide further experience in presenting this information in a technical document.

Class test is designed to assess the knowledge outcomes and in particular test the student's ability to formulate and implement simple process designs.
