- Understand the role and limitations of desalination technology in alleviating water scarcity. And, understand the basic principles, advantages and limitations of both thermal and membrane based desalination systems.
- Understand the basic principles of low pressure membrane technology such as ultrafiltration and microfiltration and their practical application in water treatment. And, be able to judge MF/UF operation and select appropriate pre-treatment and cleaning.
- Have in-depth knowledge on process design and operation of reverse osmosis plants for brackish and seawater desalination applications.
- Be able to select pre-treatment and post-treatment processes required to meet reverse osmosis design guidelines depending on raw water (surface, ground or wastewater) quality and desired permeate quality in potable and industrial applications.
- Be able to select and use appropriate water quality methods and models to monitor and predict fouling in reverse osmosis and MF/UF systems.
The course covers the following subjects:
- Desalination and membrane related technologies.
- Water sources, applications, capacities and cost.
