This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are different ways to desalinate water, freeze concentration is evaluated with the aim of characterize the process to compare the costs and it viability for the obtainment of potable water. The effects of salt solutions on freeze concentration by freezing and posterior thawing were evaluated in this study. Fractioned thawing was studied as a method to recover solutes incorporated in the ice obtained by falling-film cryoconcentrator. The ice layer used for the melting process was obtained by cryoconcentrated salt solutions, adjusting the temperature of cooling fluid to - 20 oC, in this case, ethylene glycol - water 50% (w/w). It had been worked with different concentrations such as 0.1%, 0.5 %, 1.5 %, 2.5%, 3.5%, 6 % and 8.5 %; 3 repetitions for each one. Fractioned thawing was performed at 20oC, where were made 10 fractions, keeping a similar weight for the test samples. Different parameters were studied to obtain the tracking of the process: concentration index, solute yield and thawing velocity. The results obtained showed that in the first fractions, concentration index, had values > 1 and decreased through melting, therefore; concentrated extract was collected in the earlier fractions. It would be needed to thaw 40-50 % of the ice to recover the majority of retained solutes, thus; obtain pure water. It is stated that thawing velocity increased along the increment of concentration. Moreover there were attempts on working with concentration such as 11 %, 13.5 % and 18 % but it wasn't possible to get valid results.

Book excerpt: “Blue is the new green.” This is an all-new revised edition of a modern classic on one of the most important subjects in engineering: Water. Featuring a total revision of the initial volume, this is the most comprehensive and up-to-date coverage of the process of desalination in industrial and municipal applications, a technology that is becoming increasingly more important as more and more companies choose to “go green.” This book covers all of the processes and equipment necessary to design, operate, and troubleshoot desalination systems, from the fundamental principles of desalination technology and membranes to the much more advanced engineering principles necessary for designing a desalination system. Earlier chapters cover the basic principles, the economics of desalination, basic terms and definitions, and essential equipment. The book then goes into the thermal processes involved in desalination, such as various methods of evaporation, distillation, recompression, and multistage flash. Following that is an exhaustive discussion of the membrane processes involved in desalination, such as reverse osmosis, forward osmosis, and electrodialysis. Finally, the book concludes with a chapter on the future of these technologies and their place in industry and how they can be of use to society. This book is a must-have for anyone working in water, for engineers, technicians, scientists working in research and development, and operators. It is also useful as a textbook for graduate classes studying industrial water applications.
