Biological Water Treatment Operations (ENG515)
|Organisational Unit||Engineering and Energy|
|Teaching Timetables||Murdoch S2
|Description||Provides a quantitative and detailed high-level entry into the science and engineering principles of modern biological water treatment processes. These processes are the basis of municipal wastewater (sewage) treatment, but also are often found in industrial, concentrated livestock, protected agriculture, food processing, and on-site sanitation operations. Students design and construct laboratory bioreactors with live bacteria for the processing of water, renewable energy, and bioremediation reactions, under the tutelage of experts that work with the technologies on a regular basis.|
|Unit Learning Outcomes||The completion of this unit enables students to
1. Understand the components that make modern urban and industrial waste water treatment work.
2. Design concepts for the treatment of wastewater with respect to pollutant removal, energy costs and reaction kinetics.
3. Understand and integrate bio-geochemical processes (reduction of N, S and C).
4. Predict the effect of design options on water treatment by using computer models.
5. Quantify, trouble-shoot and optimise biological wastewater treatment processes.
6. Use fundamental thermodynamical, kinetic and stoichiometric principles as the foundation for the quantification of biological and chemical aqueous processes.
7. Control the growth of microbes for the purpose of industrial and environmental processes.
8. Evaluate which processes are technologically and economically suitable.
9. Communicate with water professionals on water recycling and treatment issues.
10. Apply their knowledge of biofilm formation for a number of water related issues (e.g., diffusion controlled bioprocesses, redox mediation).
11. Understand the basis for and effects of microbial corrosion.
|Timetabled Learning Activities||Lectures: 1 hour per week; laboratory workshop: 1 x 3 hours per week.|
|Unit Learning Experiences||* Students are supplied with and analyse industrial and experimental data sets of water treating bioreactors.
* Students engage with a sophisticated wastewater treatment plant simulation build for wastewater treatment plant operators, including optimisation of the process, and the response to process upsets (loss of biomass, low temperature operation, high suspended solids income, buffer capacity problems, residual nitrate or ammonia in the effluent.
* Students carry out laboratory and model pollution events leading to process upsets such as: acidification of anaerobic digestion, nitrous acid inhibition of nitrification.
* Bioreactor operation.
* Online bioprocess control.
* Bioprocess modelling.
* Industrial visit to operating water treatment plants.
* Group work for the design and analysis of real and simulated bioprocesses.
* Investigating and qualifying the latest literature trends on technologies for water recycling.
|Other Learning Experiences||The use of online tasks accompanied by short videoclips, computer based learning activities and process simulations encourage student centred, problem based learning approaches.|
|Assessment||Assessments include a mixture of online problem based learning activites, laboratory group work, quantitative interpretation of simulated processes. Feedback from peers includes a scoring sheet versus set criteria. Verbal feedback by tutors during teamwork is available to improve the assessed tasks. Adaptive assessment methods may be used is where applicable.|
|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. CHE144 Foundations of Chemistry or equivalent.|
|Exclusions||Students who have completed ENG342 Bioenergy and Resource Recovery 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.|
