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…
Application of solar energy to seawater desalination in a pilot system based on vacuum multi-effect membrane distillation
2020
Abstract The evaluation of a novel solar seawater desalination system implemented at the University of Almeria (Spain) is presented. It integrates a solar thermal field based on static collectors and a thermal desalination system based on the vacuum multi-effect membrane distillation technology. The distillation unit has a particular innovation to increase its thermal performance, using a seawater flow to condense the steam and preheat the feed. Experiments were made under different environmental conditions to assess the role of the thermal storage system for minimizing the effect of disturbances in solar radiation. Thermal energy could be delivered at a stable temperature to the distillati…

Brackish water off-grid desalination systems for developing countries
2017
The REvivED water project aims to contribute to overcoming the drinking water challenge through desalination technology. The goal is to produce safe and affordable drinking water with a significantly reduced energy consumption compared to the current state-of-the-art technology. The overall project comprises several systems and applications with twelve pilots in total, ranging from Electrodialysis (ED) small systems for brackish water desalination to larger scale hybrid (RED/ED-RO) systems for sea water desalination. Specific attention is devoted to develop energy efficient and robust brackish water desalination systems for application in developing countries. To reduce the energy consumpti…
