WASTEWATER TREATMENT AND SEWERAGE - 2022/3

Module code: ENGM036

Module Overview

Wastewater quality and treatment have major implications for public and environmental health and the urban water cycle. In this module we will explore this through a broad ranging overview of elements of wastewater treatment and sanitation systems, including the design approaches, sewerage systems and sustainable urban drainage system (SuDs). Major wastewater (sewage) treatment processes will be covered in detail, aligning the theoretical knowledge in ENGM055 Applied Chemistry and Microbiology to practical process design, with inputs from both academics and professionals working in the sector. Approaches to developing world sanitation and wastewater treatment processes will also be covered in the module, which provide in-depth technical knowledge related to topic in ENGM289 Global Challenges in Water and Health. On successful completion of the module, the students are able to show originality in the application of knowledge of sustainable sewerage systems and wastewater treatment to specific situations.

Assessment Strategy





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

 


  • Ability to synthesize and critically assess the need for wastewater treatment for the protection of natural water bodies and public health (learning outcomes 1 and 4) is assessed through examination.

  • Analysis of the design principles and evaluation of the unit processes in wastewater collection and treatment (learning outcomes 2, 3, 4 and 5) is assessed through both coursework and examination.

  • Proposing appropriate wastewater treatment and drainage schemes  and evaluation of industrial and professional practices on wastewater treatment process design and plant operation and management (learning outcomes 1, 2, 3, 4, 5 and 6). This is assessed through the design coursework.

  • Analysis and comprehensive understanding of wastewater collection and treatment issues, both in industrialised and developing world, to evaluate the treatment process selection and management strategies (learning outcomes 1, 4, 5 and 6). This is assessed through both coursework and examination.



 

 

  Thus, the summative assessment for this module consists of:


  • Examination [Learning outcomes assessed 1, 2, 3, 4] (2 hours) {70%}

  • Coursework on i). Wastewater treatment process design, and ii). Sewerage and sustainable urban drainage [Learning outcomes assessed 1, 2, 3, 4, 5, 6] (37 hours) {30%}



 

 

  Formative assessment


  • Formative assessment will be through a range of exercises provided in the lecture notes and discussed in the tutorial sessions.



  Feedback


  • Students will receive written feedback on the coursework, and verbal feedback will be provided in the classroom.

Methods of Teaching / Learning







  The learning and teaching strategy is designed to:

 

This module provides theoretical and practical knowledge that is required in the wastewater management industry and relevant public agencies. Students will develop applied skills in sustainable sewerage and drainage (aligned with Sustainability), biological wastewater treatment, primary and secondary treatment, advanced wastewater treatment reuse, sludge treatment, unit operations and design in municipal wastewater treatment, which are commonly required for professional contribution in the field of wastewater treatment, and protection of natural water bodies and public health.

The module is delivered principally by lecturers, and industry experts who introduce industry relevant practical knowledge (aligned with Employability).

The learning and teaching activities include lectures, classroom exercises and design coursework:


  • Lecture on public and environmental health aspects of wastewater treatment and rationale behind wastewater treatment

  • Lecture and classroom exercises on wastewater collection and conveyance

  • Lecture and classroom exercises on the fundamentals and design principles of biological wastewater treatment processes

  • Lecture on microbiology of wastewater and sanitation in developing countries

  • Lecture and exercises on full scale wastewater treatment plant design and UK’s wastewater industry practices 

  • Lecture on the operation and management of full scale wastewater treatment plants and UK’s wastewater industry practices 

  • Lecture on waste stabilisation ponds and wastewater management in developing countries 

  • Lecture and exercise on introduction to wastewater treatment process simulation 

  • Coursework on design of wastewater treatment plant and sustainable urban drainage systems 

  • Independent study on wastewater treatment process design principles, wastewater collection and sustainable urban drainage 








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.

Other information

The Department of Civil and Environmental Engineering is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability and Resourcefulness and Resilience, in line with the Surrey Curriculum Framework. This module is designed to allow students to develop knowledge, skills and capabilities in the following areas:

 

Employability: Students will be supported to develop a unique set of individual, interpersonal and professional skills in water/wastewater engineering. These skills will equip students to be employment ready. The module will bring in speakers from industry to give talks on real-life process design, and career development.

 

Sustainability: Students will recognise the social-environmental impact of water/wastewater engineering technologies and policies. Real-life case studies related to sustainability issues such as renewable energy, greenhouse gas emission and climate change will be discussed, and external speakers will give talks about sustainability in the water industry.
