Freeze water desalination

Project Description

The demand of fresh water supply is exceedingly increasing due to the rapid growth of global population and economic development. With limited fresh water resources, desalination of sea water offers potential to meet the increasing water demands. Generally most current water desalination technologies are energy intensive and has high carbon footprint. This project aims to investigate the use of stored cold energy in cryofluid (liquid air, liquid nitrogen or liquid natural gas) to develop freeze desalination system. During the freezing process of sea water, salts will naturally separate as the clean ice crystals form. The work will involve developing the computational fluid dynamic modelling of the freeze desalination process and investigate the effect of the various parameters affecting the water production. The work also involves the development of a representative prototype to validate the simulation and prove the concept. A major advantage of this technology is the exploitation of cold energy stored using surplus electricity at off peak hours thus minimising cost and carbon footprint.

Funding Notes

Home/European candidates
For excellent applicants (very good first degree), there is the potential for funding for Home (UK) / EU students that will cover fees and a stipend of £14,400 un-taxed.
Overseas candidates
Overseas students are welcome to apply but should note that they will be required to be either completely self-funding, or if awarded a scholarship, they should be able to pay for their living expenses.
