Abstract
Water abstraction for cooling requirements in energy production accounts for more than 40% of the total gross abstraction in European Union, thus driving the interest in using alternative water resources for this purpose. The current study presents the follow-up of membrane distillation for treatment of wastewater from Flue Gas Desulphurization (FGD) plant for potential applications in cooling towers of power industry. The process resulted by the integration of membrane distillation, in which pure water is produced as permeate from the process, with salt crystallization, in which the concentrated solutes can be recovered as solids. Membrane crystallization is an emerging membrane process with the capability to extract simultaneously fresh water and valuable components from various streams. Successful application of crystallization for produced water treatment, seawater desalination and salt recovery has been demonstrated. In this work molecular simulations have been performed to give insights on the experimental results. Experimental tests have been carried out using a membrane crystallizer bench-scale plant to check the suitability of the utilized software. Here, with an integrated experimental-computational approach, we demonstrate that hydrophobic membranes containing also graphene materials assist the crystal-growth for mono and bivalent salts, speeding up crystal nucleation in comparison to the bulk solution.
