Deliberate Salinization of Seawater for Desalination of Seawater
Journal of Energy Resources Technology, 2017The basis of a novel method for seawater desalination is outlined. In this work, pressure-retarded osmosis (PRO) energy is obtained and used posteriorly for the reverse osmosis (RO) process for seawater desalination. Although PRO process coupled with an RO process has been studied in the past, however, in this work, there is a fundamental difference ...

Photothermal Membrane Distillation for Seawater Desalination
Advanced Materials, 2016Thermoplasmonic effects notably improve the efficiency of vacuum membrane distillation, an economically sustainable tool for high-quality seawater desalination. Poly(vinylidene fluoride) (PVDF) membranes filled with spherical silver nanoparticles are used, whose size is tuned for the aim.

Seawater desalination by electrodialysis
Desalination, 1978Abstract The first seawater desalination plant by electrodialysis in the world started its operation in September, 1974 at Noshima island of Hofu city, Yamaguchi Prefecture, Japan. The capacity of the plant is 120 m3/day and the plant has been supplying fresh water from the sea for the 800 inhabitants of the island. Batchwise operation is utilized to

The Natural Vacuum Desalination Technology in Seawater Desalination
Applied Mechanics and Materials, 2014Seawater desalination technology is an important way to solve the freshwater shortage problem. Natural vacuum desalination (NVD) technology generates very low pressure environment in the headspace of 10 meters high water column. The weight of the water column is balanced by atmospheric pressure, and low-temperature desalination proceeds in the ...

Integrated membrane systems for seawater desalination
Desalination, 2006In the present work, seven different flow sheets for seawater desalination process have been analyzed. In each of them, except for the first (FS1) constituted by the only RO unit, different membrane units have been integrated in order to reach all the important benefits in the logic of process intensification: RO operates on NF permeate in FS2; both MF

Integrated membrane operations for seawater desalination
Desalination, 2002Reverse osmosis is widely applied to water desalination because of the relatively low cost of the process. Besides the well defined role that this technology plays in the desalination scenario, in the last years, from all over the world, demand for lower costs and higher quality of water has been advanced.

Optimization of chemical structures for seawater desalination
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2019The stable conformation of a chemical structure can be searched by optimizing the spatial coordinates of the given arrangement of functional groups that determine the structure. Typically, the process seeks to optimize the geometry of a known particular arrangement.

Thermoresponsive Magnetic Nanoparticles for Seawater Desalination
ACS Applied Materials & Interfaces, 2013Thermoresponsive magnetic nanoparticles (MNPs) as a class of smart materials that respond to a change in temperature may by used as a draw solute to extract water from brackish or seawater by forward osmosis (FO). A distinct advantage is the efficient regeneration of the draw solute and the recovery of water via heat-facilitated magnetic separation ...
