  • Use of Composite Materials in the Desalination Process

    The vast majority of the Earth’s surface is covered by saltwater and people living on the remaining land need fresh water to sustain life. But, as our readers are well aware, more than 1 billion people lack reliable access to fresh water and that count is only expected to grow. Remarkably, almost 60 percent of the world’s population lives less than 60 km from a seacoast. Desalinated ...

  • Seawater Desalination

    Seawater covers 71% of the planet surface and represents 97% of the world's water,and seawater has a lot of resources to be explored.Along with recycled wastewater, it is one of the few rainfall-independent water sources.However,in the current condition,seawater cannot be used directly because of the high salinity.To solve it,many methods of desalination are adopted. Desalination is a process ...

  • Comparative analysis of the thin-film desalination plant process

    Thin-film installations with different heating surface orientations are widely used in seawater technology. Despite the presence of various thermal schemes and the construction of evaporating devices for installations of this type, comparisons of their power output are not available. We have carried out a comparison of the thermal schemes of MSF and thin-film installations in order to determine ...

  • Thermodynamic efficiencies and GHG emissions of alternative desalination processes

    Three alternative approaches to desalinating seawater were evaluated with respect to their thermodynamic efficiencies and greenhouse-gas emissions. The technologies considered were multistage flash distillation (MSF), reverse osmosis (RO), and membrane distillation (MD). The analysis was based on published stream data from large-scale operational MSF and RO facilities and experimental-scale data ...

  • Process control in multi-stage flash desalination industry

    Process control is an essential part of the desalination industry that requires to be operated under optimum conditions to increase the lifetime of the plant and reduce the unit product cost. Improved process control is a cost-effective approach to energy conservation and increased process profitability. The Multi-Stage Flash (MSF) plant involves many complicated operations related to steam, ...

  • Seawater desalination using forward osmosis process

    This study aims to evaluate the feasibility of the forward osmosis (FO) process for seawater desalination. The leakage of boron from the seawater into the draw solution was also studied. According to the WHO guideline, the maximum permissible limit of boron in drinking water is 2.4 ppm. Preliminary results of boron rejection by forward osmosis membrane were found to be 60–70%. ...

  • Seawater desalination — a green technology?

    The 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 or reducing pollution of the atmosphere, ...

  • An overview on nuclear desalination

    One of the peaceful uses of nuclear energy is in freshwater production. The present work focuses on the recent world water situation, large-scale desalination processes, electricity production, and the features required by advanced inherent and passive safe reactors. The relevant economical assessment of these adapted reactors for water-electricity cogeneration have been carried out and compared ...

  • Taking the pressure off desalination

    California-based PAX Pure hopes to offer a new solution to water scarcity with its groundbreaking water purification tool. Developed by Jay Harman and Tom Gielda, PAX Pure technology desalinates and demineralizes water without membranes, moving parts or chemicals. Instead, the technology simply mimics high-altitude conditions. The big challenge with conventional ...

  • The role and importance of nuclear desalination

    Desalination needs energy and saline water as the process raw material. The desalination process where the needed energy is generated by nuclear sources and/or the saline water is supplied from a nuclear installation, such as cooling water from the power unit, is usually called nuclear desalination. Comparing nuclear desalination with alternative water sources in general and to nonnuclear ...

  • Advances in desalination technology

    Seawater desalination has been the cornerstone of the Middle East's water supply strategy since the mid-1950s, and most of the installed desalination capacity is still provided by multistage flash evaporators. But, desalination is changing. In fact, the term "desalination" is no longer limited to seawater applications; desalination technologies are now routinely employed to desalinate brackish ...

  • Sustainable desalination: environmental approaches

    Abstract The environmental issues of possible concern during construction and operation of desalination plants (mainly large-scale facilities) include impacts that are common to many coastal development projects (e.g. land use and aesthetic impacts), as well as specific impacts associated with the elements of the desalination system and auxiliary infrastructure. In the latter category ...
