Environmental Water Chemistry (ENG507)

School School of Engineering and Information Technology
Credit Points 3
Availability MURDOCH: S1-internal
Teaching Timetables Murdoch S1
Description Students will acquire the knowledge of and skills to utilise the most important water chemistry principles and tools with particular emphasis on equilibrium chemical speciation. The quantification of the concentration of chemical species will be emphasised, since this is the differentiator between the benign versus toxic presence of any contaminant in water as well as the determinant whether a co-occurring species affects or is irrelevant to the change in water composition that the treatment engineer is attempting to produce.
Unit Learning Outcomes The completion of this unit enables students to:
1. Understand the concept of chemical equilibrium of species in water.
2. Understand the utility and calculation of hardness, alkalinity, and various concentration metrics in aqueous systems.
3. Understand the processes and quantify the species in weak acid and base aqueous equilibria.
4. Utilize and calculate the equilibrium species in simple multiphase systems.
5. Utilize and calculate the equilibrium speciation in simple, environmentally relevant aqueous systems including use of electron balances and free energy calculations.
Timetabled Learning Activities Lectures: 2 hours per week; workshops: 1 hour per teaching fortnight starting in Week 2; computer workshops: 1 hour per teaching fortnight.
Unit Learning Experiences The lectures will involve a combination of traditional lecture presentations and interactive learning activities. Weekly workshop and computer sessions will involve the application of concepts from lectures to solve problems and do to so in a peer led team environment.
Assessment The learning and assessment strategies are based on the student's understanding and facility in using chemical equilibrium principles and simulation tools to understand the major aqueous speciation in natural water systems and to design appropriate chemical water treatment technologies to meet specified objectives. Therefore, in assessments students must provide the rationale and quantitative calculations, the aqueous speciation before and after chemical perturbations in simple aqueous systems. Individual and teamwork solutions to aqueous chemistry problems will be used. Verbal feedback by tutors during problem solving sessions 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 completed ENG340 Environmental Water Chemistry cannot enrol in this unit for credit.

Graduate Diploma in Engineering (GradDipEng)
Graduate Diploma in Water Treatment and Desalination (GradDipWatTrmt) [New in 2016]
Master of Engineering (ME)
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.
