ADVANCED WATER AND WASTEWATER TREATMENT - 2018/9

Module code: ENG3204

Module Overview

The module introduces students to advanced water and wastewater treatment and reuse technologies and principles. The potential for water and material recycling and recovery via the use of sustainable treatment techniques will be introduced with the aim to minimise waste production and maximise water and material reuse.  Some process design concepts will be introduced for those technologies that have more potential for wider practical applications. The module will build upon the information about the concepts and theory of conventional water and wastewater treatment introduced during the module on Environmental Engineering and Hydrology (ENG3177).

Module content

Introduction to wastewater treatment


Characteristics of municipal wastewater and industrial effluent.
Purpose of conventional and advanced processes.


Conventional wastewater treatment (limited potential for recycling/reuse)


Coagulation/flocculation
Chemical precipitation/co-precipitation


Biological treatment processes


Aerobic/anaerobic digestion (introduce design concepts)
Membrane bioreactors (MBRs) and Upflow sludge blanket filtration (USBF) or rotating biological contactors (RBCs)


Advanced wastewater treatment processes (emphasis on  resuse of resources)


Activated carbon adsorption (introduce design concepts)
Membrane separation techniques  (reverse osmosis)
Sludge treatment for reuse


Chemical oxidation and disinfection processes


chlorine,
chlorine dioxide
ozone
ultraviolet irradiation.
byproduct formation and control.


Emerging pollutants


Pesticides and herbicides
pharmaceuticals, endocrine disrupting chemicals
advanced oxidation processes.


Future of water and wastewater treatment


Current issues: energy and chemicals consumption, climate change, population growth, water stress.
Possible solutions: water reuse and recycling, decentralised treatment, catchment management. 

Assessment pattern

Assessment type Unit of assessment Weighting
Examination EXAMINATION (2 HOURS) 70
Coursework COURSEWORK: PART A: CASE STUDY REPORT (20%); PART B CASE PRESENTATIONS (10%) 30

Alternative Assessment

Alternative Assessment: Alternative assessment for the oral presentation of courseworkwill be delivered by students in the presence of the module delivery organiser in an office environment or via Skype if more convenient.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to:


Explain the principles of municipal  and industrial wastewater treatment processes (LO:1,2,3)
Compare and appraise conventional and advanced  technologies associated with  wastewater & waste treatment and reuse (LO:4,5,6,7)
Evaluate the concepts of sustainability and reuse when selecting treatment options, with an emphasis on closed-loop treatment processes rather than end of pipe (LO:5,6,7)


The summative assessment for this module consists of:


Coursework:  case study report (20%) and associated presentation (10%) [Learning outcomes assessed:1,3-7,a,b,h-j,l,n,o] (30%, 40 hours)



Examination [learning outcome: 1-7;b-e,g,i] (70%, 2 hours)


Formative assessment and feedback

Formative assessment, in the form of a comments and (where appropriate) worked solutions, will be through a range of exercises during the lecture and tutorial sessions. The coursework will also provide a vehicle for formative feedback both written (and returned with the coursework submission) and verbally (during a debrief session).

Module aims

  • To introduce students to the fundamentals and principles of advanced water and wastewater treatment and reuse technologies, that have potential for water reuse, material recovery and waste minimisation.
  • The students will be provided with the knowledge required for them to be able to select the most appropriate and sustainable treatment techniques for a particular wastewater stream.
  • They will also be able to design a selection of treatment processes that have wider practical applications.
  • When designing and selected treatment processes during the coursework they will be encouraged to consider multiple factors, including sustainability, the environment, public health and economics.

Methods of Teaching / Learning

The learning and teaching strategy for this part of the module is designed to introduce students to fundamental and advanced wastewater and waste treatment and reuse technologies and principles.  The potential for water and material resource recovery via the use of sustainable treatment techniques will be introduced with the aim to minimise waste production and maximise water and material reuse.  Some process design concepts will be introduced for those technologies that have more potential for wider practical applications. Students will be encouraged to consider multiple factors, including sustainability, the environment, public health and economics, when undertaking case studies for coursework.

The learning and teaching methods include:


One session on “Introduction to Water and Wastewater treatment” (3 h).
Two sessions on “Biological Treatment Processes” (6 h).
Two sessions on “Physical and Chemical Processes” (6 h).
One session on “Chemical Oxidation and Disinfection Processes” (3 h).
One session on “Emerging pollutants” (3 h)
One session on the “Future of Water and Wastewater Treatment” (3 h).
A site visit to a wastewater treatment plant (3h)
Case studies presentations (3h)


All these sessions will be lectures containing tutorial-style questions which help the students to apply the associated theory and concepts.


In addition, there will be a piece of coursework (40 h) where the students work on case studies about a water or wastewater treatment topic of their choice. These case studies will involve a consideration of water and wastewater recycling and/or sustainability. 
The students giving presentations about their case studies and receiving feedback (3 h).
Independent learning (72 h) will also be required by the module.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
