The pressure was felt by the scientific community which started investigations for cheap and efficient ways to treat sea water. Nowadays, a number of well proven technologies exist with advantages and disadvantages which make each one of them more suitable in specific sites. As in any other case, the application of new technologies which can enhance the efficiency of such processes is always required. In this work we investigated the usage of electrohydrodynamic atomization (EHDA) to improve the efficiency of the thermal desalination process. It is divided into three parts: the study of the spray, the characterization and design of a multinozzle device and experiments with a single-effect electrohydrodynamic thermal desalination device. From the results it could be inferred that EHDA enhances the evaporation by providing wider dispersion of the generated droplets. Additionally, the proposed design for the multinozzle device was proven to be stable and suitable for desalination processes. Lastly, the single-effect electrohydrodynamic thermal desalination device operated stable with good performance ratios with the use of a membrane.
