Decentralised and Industrial Water Treatment (ENG602)
|Organisational Unit||Engineering and Energy|
|Teaching Timetables||Murdoch S1
|Description||Water treatment for potable purposes has been driven predominantly by the need of large communities for drinking water. This has led to highly centralised treatment and distribution systems. This unit introduces the student to the design, characteristics, and function of treatment operations, implementation strategies, operation and maintenance approaches, and specific challenges associated with providing water of appropriate quality for decentralised users; such as mines, farms, remote communities, industrial and advanced manufacturing processes, and natural environment maintenance.|
|Unit Learning Outcomes||The completion of this unit enables students to
1. Understand the concept and characteristics of fit-for-purpose water for representative agricultural, industrial, aquaculture, sanitation, boiler feed, and remote community applications.
2. Understand in what ways and to what degree conventional water treatment unit operations can be down-scaled and adapted to suit non-conventional applications.
3. Gain a working and basic design understanding of water treatment unit operations applicable to small-scale implementation and specific decentralized applications.
4. Understand and quantitatively simulate how small-scale and non-potable water treatment operations perform over a range of feed water types, and environmental and infrastructure conditions and be able to predict the water contaminants which a unit operation will remediate.
5. Critically differentiate between the advantages and disadvantages of alternative treatment trains possible to achieve the same water quality objective.
6. Critically review and communicate the function of a decentralized, 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; workshops: 1 x 2 hours per week.|
|Unit Learning Experiences||* Apply and model mass balances, reactor design analysis, chemical kinetics, and mass transport concepts to decentralised and small-scale water treatment processes.
* Group work for the design and analysis of decentralised and small-scale water treatment trains.
* Investigating and qualifying the recent trends, innovations, and concerns in decentralised and small-scale water treatment.
* Analysis of industrial and natural water quality data sets and determination of treatment trains relative to product water quality objectives.
* Design of individual potable and non-potable water treatment unit operations in response to given physical and water quality inputs, including:
o Particulate loading ranges in total solids and total suspended solids from 1 - 100 mg/L
o Organic loading ranges in TOC and BOD from 0.5 - 10,000 mg/L.
o Dissolved contaminants loadings for salinity from 0.5 - 40 g/L as well as specific trace high toxicity species (e.g., arsenic, lead, fluoride, nitrate)
* Treatment process chemical reagent and energy demand versus product balances.
* Implementation case specific literature review and analyses.
|Assessment||The learning and assessment strategies are based on the student's understanding and facility in applying the principles, simulation tools and material reviews to select the appropriate material and its operational specifications to achieve given water treatment objectives. Therefore in assessments students must provide the rationale and quantitative calculations supporting choice, scale, and application specification of water treatment technologies. 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||Successful completion of ENG510 Physicochemical Water Treatment Operations and ENG515 Biological Water Treatment Operations (or their equivalent with permission from the unit coordinator).|
|Exclusions||Students who have successfully completed ENG459 Sustainable urban Water Systems 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.|
