Advanced Course in Water Treatment Processes
Brief Description
The Advanced Course in Water Treatment Processes provides you with an overview of both the theoretical and practical aspects of industrially relevant advanced water treatment processes. Topics include chemical water treatment, advanced oxidation processes, calculating the required chemical doses required for various chemical water treatment processes, desalination and membrane technology. The course also includes a review of the current South African water crisis and the need for alternative water resources, development of new treatment processes, energy considerations, basic water chemistry, examples of advanced water treatment technologies, the scientific basis and limitations, operational considerations, case studies and advances in membrane technologies.
Learning Outcomes
After successfully completing this course, you will be able to calculate the required chemical doses required for various chemical water treatment processes explain and identify advantages of various advanced oxidation processes design advanced oxidation processes for removal of contaminants identify technologies for desalination explain and compare membrane-based and thermal-based desalination explain the basic principles of low pressure membranes explain the basic principles of high pressure membranes select and design a membrane filtration system given specific feed and effluent requirements define and explain fouling and cleaning in low pressure membranes define and classify fouling and propose mitigation activities to control fouling in high pressure membrane systems evaluate need for pre-treatment and for post-treatment in membrane systems explain the basic principles of electrodialysis and ion-exchange, and evaluate the quality of an effluent water stream using BAT standards.
