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 ...

Seawater desalination — a green technology?
Journal of Water Supply: Research and Technology-Aqua, 2010The need for resource-saving, low-impact “green” desalination technologies is evident as the use of desalination accelerates in many parts of the world. The concept of “best available techniques” (BAT) aims at the identification of state of the art technologies, processes, or methods of operation which indicate the practical suitability for preventing ...

Environmental impact of seawater desalination plants
Environmental Monitoring and Assessment, 1991Enormous amounts of seawater are desalted everyday worldwide. The total world production of fresh water from the sea is about 2621 mgd (9.92 million m(3) day(-1) 1985 figures). Desalting processes are normally associated with the rejection of high concentration waste brine from the plant itself or from the pretreatment units as well as during the ...

Utilization of gamma-irradiation for seawater desalination
Applied Radiation and IsotopesWe present a method used for the seawater desalination with low doses of gamma irradiation (up to 1.0 kGy) emitted from Co-60 source. For seawater, the method is based on laboratory measurements at room temperature. The optical and electrical characterization of Mediterranean Sea (MS) coast, Red sea (RS) coast, and sodium chloride (NaCl) solution were ...

How Mangroves Desalinate Seawater
Physiologia Plantarum, 1968AbstractWater relations of a number of mangroves and other halophytes were studied. All mangroves had high negative pressure in the xylem (30 to 60 atm) which more than balances the osmotic pressure of the seawater (25 atm). Freezing a short stem section of an attached twig always resulted in wilting caused by eavitation of the tensile sap ...

Seawater desalination by reverse osmosis
Endeavour, 1980Abstract Until comparatively recently the purification of sea or brackish water depended largely on some form of distillation. In recent years, however, a number of industrial concerns have directed increasing attention to processes depending on reverse osmosis.
