Water Technology and Desalination Scholarship 2017

Heriot-Watt University and the International Desalination Association are pleased to offer a scholarship for students to this joint Masters programme. Read more about eligibility criteria and how to apply.


Water resource management is a global issue that is becoming increasingly important. With a rapidly growing world population, greater urbanisation and a changing climate putting pressure on freshwater resources, water resource management and the technologies that support it, will play a large part in providing fresh water to meet basic human needs.

Water Technology and Desalination is designed for science and engineering graduates, as well as practising engineers, who wish to gain specialised knowledge in water treatment with an emphasis on membrane technology.

The global scarcity of fresh water and ever increasing requirement for desalination and recycling creates a high demand for water technologists. This applied programme ensures students acquire the necessary skills to meet the current market demand.
Prof. Bhaskar Sen Gupta

The programme aims to provide a sound understanding of a range of technologies that can be developed to provide safe, accessible water supply from saline groundwater and seawater. In particular, there is a technical focus on the design parameters and processes underpinning their efficient performance and operation. Students will also develop a critical awareness of the wider issues of resource management within the context of global change and the challenges presented by the need for desalination to be delivered on a technically robust and sustainable basis.
