Water Treatment Operations (ENG343)

Organisational Unit Engineering and Energy
Credit Points 3
Availability MURDOCH: S2-internal
Teaching Timetables Murdoch S2
Description This unit introduces the student to the function and design of the primary physical and chemical technologies which are used to treat water. These technologies are the basis of municipal potable water treatment, as well as industrial, mining, protected agriculture, food processing, and even under-sink residential applications. Particular emphasis is placed on the principles of operation and the manipulation of design parameters, allowing the technologies to be adapted to different water sources and treatment objectives.
Unit Learning Outcomes On successful completion of the unit the student will be able to:
1. Understand the purpose and function of the treatment operations comprising a conventional municipal surface water treatment train.
2. Analyse and synthesise source water quality data and product water quality information to estimate the appropriate type and size of water treatment train.
3. Understand and quantitatively predict the water contaminants which a unit operation will remediate.
4. Critically evaluate malfunctions or inefficient operation of water treatment operations at a basic level and generate recommendations for remedy of the poor performance.
5. Access and synthesise technical and professional knowledge regarding a water quality problem in the news and then communicate the problem and potential solution to a peer audience.
6. Critically review and communicate the function of a physical and/or chemical water treatment process, including its relationship to alternative and partner water treatment unit operations.
Timetabled Learning Activities Lectures: 1 x 2 hours per week; workshop 1 hour per week.
Unit Learning Experiences The unit consists of lectures, workshops, and guest lectures. The learning experiences will include both individual and group exercises. The student will be exposed to multiple sources of information including lectures, textbooks, journal articles, news bulletins and reports, engineering design documents, handbooks and reports, grey literature, and specially developed digital media. This information will cover:
* Treatment of surface water versus groundwater versus recycle sources.
* Analysis of industrial and natural water quality data sets and determination of treatment trains relative to product water quality objectives.
* Design of individual potable water treatment unit operations in response to given physical and water quality inputs.
* Application of model mass balances, reactor design analysis, chemical kinetics, and mass transport concepts to treatment process evaluation and design.
* Mechanistic versus empirical model simulation of filtration, coagulation/flocculation, and disinfection. * Treatment process chemical reagent versus product balances.
* Industrial visit to operating water treatment plants.
* Group work for the design and analysis of real and simulated water treatment design.
* Investigating and qualifying the recent trends, innovations, and concerns in water treatment.

Internet Access RequirementsMurdoch units normally include an online component comprising materials, discussions, lecture recordings and assessment activities. All students, regardless of their location or mode of study, need to have access to and be able to use computing devices with browsing capability and a connection to the Internet via Broadband (Cable, ADSL or Mobile) or Wireless. The Internet connection should be readily available and allow large amounts of data to be streamed or downloaded (approximately 100MB per lecture recording). Students also need to be able to enter into online discussions and submit assignments online.
