WATR06010 2018 Advanced Wastewater Treatment
This module explains the fundamental characteristics and operational processes for a range of advanced wastewater treatment processes for the additional removal of organic material, suspended solids and nutrients compared to conventional systems. Topics covered include replacement/upgrading of existing systems to address more stringent effluent requirements and/or drive greater efficiencies, the use of chemicals to remove phosphorus, enhanced biological removal of phosphorus and/or nitrogen, moving bed biofilm reactors, filtration, membrane, adsorption and advanced oxidation technologies.
Learning Outcomes
On completion of this module the learner will/should be able to;
Describe the range of advanced wastewater treatment processes and explain where and when they can be used effectively and efficiently
Illustrate how various enhanced biological systems for the reduction/removal of phosphorus and/or nitrogen can be integrated with conventional wastewater treatment systems
Outline how inorganic coagulants are used to remove phosphorus from wastewater, compute appropriate doses and explain how the system should be operated and monitored
Illustrate how tertiary filtration systems operate and explain how the system should be operated and monitored
Discuss how advanced wastewater treatment systems should be operated, monitored, trouble-shooted and managed to achieve legal, environmental and economic objectives.
Teaching and Learning Strategies
This module will be delivered using blended learning techniques. This will include online lectures (via Adobe Connect or similar), workshops and site visits augmented by independent learning and directed learning. This approach is expected to address student-learning needs. Moodle will be used to upload educational material (i.e. presentations and recordings of online lectures plus supplementary reading material) and as a means of assessment (e.g. quizzes, uploading assignments and journals). This blended approach (lectures and workshops) brings students together to facilitate group learning.
Module Assessment Strategies
This module is 40% Continuous Assessment and 60% Final Exam.
Assessment will consist of two MCQs in weeks 4 - 6 and 8 - 10.
A practical assignment issued in weeks 3 - 4 must be submitted in weeks 10 - 12.
Repeat Assessments
Repeat Continuous Assessment and/or Final Exam.
Indicative Syllabus
1. Describe the range of advanced wastewater treatment processes and explain where and when they can be used effectively and efficiently

- Range of Tertiary Physical, Chemical and Microbiological processes
2. Illustrate how various enhanced biological systems for the reduction/removal of phosphorus and/or nitrogen can be integrated with conventional wastewater treatment systems
- Sequencing of environmental conditions (i.e. aerobic, anaerobic, and anoxic), Process Schematics, Intermittent Aeration, modified Oxidation Ditches, SBRs (full batch, upflow displacement, aerobic granular sludge) and RBCs.
- Processes such as Modified Ludzack-Ettinger (MLE), A2/O, Step Feed, Modified Bardenpho, UCT, Anamox and PhoStrip.
3. Outline how inorganic coagulants are used to remove phosphorus from wastewater, compute appropriate doses and explain how the system should be operated and monitored
