Water desalination by capacitive electrodialysis: Experiments and modelling
2020
Abstract Electrodialysis-related technologies keep spreading in multiple fields, among which water desalination still plays a major role. A new technology that has not yet been thoroughly investigated is capacitive electrodialysis (CED), which couples the standard ED with capacitive electrodes. CED has a number of advantages such as removal of toxic products and system simplification. Little mention is made of this technology in the literature and, to the best of our knowledge, no modelling works have ever been presented. In this work, the CED process has been studied through experiments and modelling. A CED model is presented for the first time. With a simple calibration based on macroscop…
A novel fluid-structure 2D modelling tool for the assessment of membrane deformation effects on electrodialysis units performances
An ultrathin suspended hydrophobic porous membrane for high-efficiency water desalination
2017
Abstract An ultrathin highly fluorinated porous membrane was designed for a large production of desalted water at very low energy consumption. Imprinting water droplets were used through a low thermally conductive tetra-fluoroethylene (TFE)/2,2,4-trifluoro-5-tri-fluorometoxy-1,3-dioxol (TIT) (HYFLON AD 60) solution and the generated porous nanofilm was suspended onto a polyethersulfone (PES) honeycomb texture. The very tiny fluorinated thickness together with a large number of small-shaped pores provided the membrane for enhanced anti-wetting surface properties, extremely reduced resistance to water vapor transfer and outstanding thermal efficiency. Fine materials structure-transport relati…
Long term analysis of small desalination plant for potable water supply of tourist areas (in Sicily)
2013
The main aim of this work is to gain information on the working conditions of a desalination plant in Sicily, on the costs of produced desalinated water and on the perspectives of new plants to be built in the island, in order to evaluate the long term performance of a desalination plant in a small island for potable water supply. At the same time, because the high operational costs, the work tries to provide green power alternatives for the plant as well. As a pilot we will consider the Lipari Island which has a MED-MVC (Multiple Effect Distillation- Mechanical Vapor Compression) plant. It is important to underline that even though the pilot refers to a Sicilian Island, the developed proce…
