Thermodynamic model for a reversible desalination cycle using polyelectrolyte hydrogels
(Corresponding) Rud O., Košovan P.
Topic:
Desalination
We propose a novel desalination scheme which employs the hydrogels as a tool to draw salt ions from a brine with low salinity to a brine with high salinity. As a driving force we use the fact that the volume of polyelectrolyte gel does depend on the surrounding salinity. While the salinity...Read more
Mixed Nanostructures/PES/ RO Membrane for Water Desalination
(Corresponding) Shalaby M., Abdallah H., Shaban A., Chetty R., Kumar M.
Topic:
Desalination
Different nanomaterials graphene, zinc nanorode and zinc nanosephere were used in membrane preparation. Polyethersulphone as a main polymer was blended with nanosoultions of these nanomaterials, then coated by composite coating layer consists of polyvinylacohol and titanium dioxide nanotubes to...Read more
Phase Diagram Modelling of a Multi-component Aqueous Solution of Katwe Salt Lake, Uganda
(Corresponding) Lwanyaga J., Kasedde H., Kirabira B.
Topic:
Desalination
A methodology is developed to compute the phase diagram of a hexary system and to determine the mineral precipitation sequence upon removal of water. The methodology is applied to construct the phase diagram and precipitation sequence of the system (〖Na〗^+,K^+)(〖Cl〗^-,〖SO〗_4^(2-),〖CO〗_3^(2-)...Read more
Novel super-hydrophobic carbon nanotube-based nanomaterial for membrane distillation
Ouda M., Wadi V., Hai A., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Desalination
Membrane distillation (MD) is a low-grade heat-based emerging technology found viable for seawater desalination. Membrane properties such as high hydrophobicity, mechanical strength, and thermal stability are crucial in assessing the compatibility of a membrane for use in this application. In this...Read more

SUPERHYDROPHOBIC NANOPARTICLE-COATED PVDF-HFP MEMBRANES FOR INCREASED FLUX AND FOULING RESISTANCE MEMBRANE DISTILLATION
(Corresponding) TOURNIS I., TSIOURVAS D., SIDERATOU Z., SAPALIDIS A.
Topic:
Desalination
Water is one of the most precious natural resources of the planet. Global water demand is expected to increase by 20-30% in near future, mainly due to the increase of industrial activities and domestic use. In this context, up to now, many water treatment technologies have been proposed to address...Read more
The thermodynamic model of improved desalination using hydrophobic polyelectrolyte gels
(Corresponding) Rud O., Prokacheva V., Uhlik F.
Topic:
Desalination
We study a weak polyelectrolyte hydrogel and its application as a desalination agent. We model the desalination process as a four-step reversible thermodynamic cycle transferring ions from a low salinity solution to a high salinity one. As a driving force for ions movement, we use the fact that...Read more

Recent Developments in Solar-Powered Membrane Distillation
Jawed A., Nassar L., Hegab H., Merwe R., AlMarzooqi F., Banat F., (Corresponding) Hasan S.
Topic:
Desalination
Freshwater scarcity remains one of the most crucial issues facing our world. Although the traditional membrane distillation (MD) technique can efficiently produce clean water irrespective of climate conditions, the process wastes a lot of energy. Thanks to the development of photo-thermal materials...Read more

Water desalination using polyelectrolyte hydrogel. Gibbs ensemble modeling
(Corresponding) Rud O., Laktionov M., Nova L.
Topic:
Desalination
Polyelectrolyte hydrogels possess the remarkable ability to efficiently absorb large volumes of water through an osmotic membrane by exerting swelling pressure. Conversely, the insoluble cross-linked structure of the gel allows for dewatering when triggered by external stimuli such as temperature...Read more
