Physicochemical Water Treatment Operations (ENG510)
|Organisational Unit||Engineering and Energy|
|Teaching Timetables||Murdoch S2
|Description||This unit introduces students to the function and design of the primary physical and chemical treatment technologies which are used to treat water. Particular emphasis is placed on the principles of operation and the manipulation of design parameters allowing technologies to be adapted to different water sources and treatment objectives. Understanding these also forms the basis for understanding more specialised treatment operations as well as hybrids. The student will be introduced to the means of and limits to sizing of each operation.|
|Unit Learning Outcomes||The completion of this unit enables students to
1. Understand the purpose and function of unit operations that comprise a conventional municipal surface water treatment train.
2. Understand how unit operations may be combined, modified, and utilized to meet specific water treatment objectives.
3. Design the basic scale and operation of the primary physical and chemical water treatment processes.
4. Understand and quantitatively predict the water contaminants which a unit operation will remediate and at a basic level be able to troubleshoot malfunctions of these unit operations.
5. Critically review and communicate 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: 2 hours per week; workshops: 1 hour per week.|
|Unit Learning Experiences||* 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.
* Apply and model mass balances, reactor design analysis, chemical kinetics, and mass transport concepts to treatment process evaluation and design.
* Energy versus filtration efficiency optimization of media filters.
* 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.
|Assessment||The learning and assessment strategies are based on the student's understanding and facility in using principles and simulation tools to determine and design appropriate physical and chemical water treatment technologies to meet specified objectives. Therefore in assessments students must provide the rationale and quantitative calculations supporting choice, scale, and operation of unit operations. Feedback from peers includes a scoring sheet versus set criteria on a research paper. Verbal feedback by tutors during teamwork is available to improve the assessed tasks.|
|Prerequisites||Enrolment in graduate coursework in a Murdoch Environmental, Energy, Physics, Electrical, Chemical or Metallurgical Engineering discipline. Other Murdoch graduate students with equivalent qualifications may be enrolled with permission from the unit coordinator.|
|Exclusions||Students who have previously completed ENG343 Water Treatment Operations may not enrol in this unit for credit.|

|Internet Access Requirements||Murdoch 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.|
