Description

This module provides the learner with the fundamental characteristics and operational processes for a range of Advanced Drinking Water Treatment Systems including ortho-P dosing for lead mitigation and removal, ultraviolet irradiation technology, advanced water filtration, activated carbon filtration, membrane technologies, taste and odour improvement, advanced oxidation technologies including ozonation, aeration, water softening, desalination, and pH adjustment.

 

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Describe the range of advanced drinking water treatment processes and explain where and when they can be used effectively and efficiently.

2.

Outline the potentially harmful and deleterious effects that various substances and micro-organisms may have on consumers of drinking water from both polluted and natural sources.

3.

Describe the processes that would positively impact on the quality of drinking water produced from a number of sources and comparatively assess the relative costs and benefits of employing such technologies.

4.

Sample, test and monitor the water quality from advanced drinking water treatment processes and provide an analysis of the success of such systems for various water sources and potential uses of the treated water.

5.

Identify technologies to solve issues for drinking water supplies and determine the appropriate applications of such technologies to solve problems.

Teaching and Learning Strategies

The teaching and learning strategy is based on the provision of on-line lectures, tutorials and group
workshops that incorporate elements of enquiry and project-based learning along with practical laboratory demonstrations, case study assignments, and guest lecturers.

Module Assessment Strategies

Final written examination and continuous assessment consisting of Moodle MCQ assessment (multiple choice quiz), workshop laboratory practical, and an individual practical case study assignment involving a written report.

Repeat Assessments

The learner must undertake repeat final written examination and/or continuous assessment project
work depending on the particular failed element to achieve an overall pass grade.

Indicative Syllabus

1. Overview of conventional drinking water treatment processes and their limitations

2. Introduction to advanced treatment processes and applications to improving the quality of drinking water supplies. Physical methods for particulate removal and optimisation of chemical dosing for DAF and other flocculation processes.

3. Lead removal and mitigation processes within water distribution networks. Ortho-P dosing for lead removal.

4. Membrane technologies including reverse osmosis, nanofiltration, ultrafiltration and microfiltration for fine particle removal.

5. Advanced oxidation processes for the destruction of organic and inorganic substances in water, including hydroxyl radical, ozone, and UV based AOPs.

6. Advanced media filtration systems including granular activated carbon and pressure filters.

7. Alternative disinfection technologies for cryptosperidium and giardia destruction including UV radiation, ozonation, and membrane technologies.

8. Water softening, taste and odour reduction, pH adjustment and aeration to improve drinking water treatment and quality. Certification and validation.

9. Desalination and dissolved solids treatment processes.

10. Cost-benefit assessment and implementation of advanced treatment processes and plant upgrades. Case studies.

Twort's Water Supply, Seventh Edition, has been expanded to provide the latest tools and techniques to meet engineering challenges over dwindling natural resources. Approximately 1.1 billion people in rural and peri-urban communities of developing countries do not have access to safe drinking water. The mortality from diarrhea-related diseases amounts to 2.2 million people each year from the consumption of unsafe water.

This update reflects the latest WHO, European, UK, and US standards, including the European Water Framework Directive. The book also includes an expansion of waste and sludge disposal, including energy and sustainability, and new chapters on intakes, chemical storage, handling, and sampling. Written for both professionals and students, this book is essential reading for anyone working in water engineering.

  • Features expanded coverage of waste and sludge disposal to include energy use and sustainability
  • Includes a new chapter on intakes
  • Includes a new chapter on chemical storage and handling
