  • Innovative seawater intake for reverse osmosis desalination plants

    Seawater desalination plants typically consist of four major unit operations: seawater intake, pretreatment, Reverse Osmosis (RO) stage, and posttreatment and brine discharge. The best way is to go through vertical beach wells, but the increase of the production capacity of the plants built in recent years makes open intake the only solution. These open ocean intakes draw seawater through the ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Seawater desalination using reusable type small PWR

    Demand for seawater desalination is increasing, especially in regions such as the Middle East and North Africa, where populations are growing at a high annual rate. If such demand is met by fossil fuel energy, the influence on the environment, such as global warming, cannot be disregarded. Since these regions are behind in their preparedness of social capital infrastructure, such as power ...

  • On the performance limitation of reverse osmosis water desalination systems

    The performance of Reverse Osmosis (RO) water desalination processes was investigated using a simulated brackish water plant based on spiral-wound membranes. A semi-rigorous mathematical model was employed in the simulation to calculate the water and salt fluxes at any point along the filtration channel. The effects of two key parameters, namely the transmembrane pressure and membrane surface ...

  • Coupling strategies for desalination plants with gas cooled reactors

    Of late, high temperature gas cooled reactors have received significant attention due to many desirable operational and safety characteristics. Potable water has become more and more scarce due to the increasing population and environmental problems. Seawater desalination is an important consideration when searching for a supply of potable and industrial water. This study deals with possible ...

  • Assessment of an ultrafiltration pre-treatment system for a seawater reverse osmosis plant

    The seawater reverse osmosis system requires extensive pre-treatment in order to ensure reliable performance. The conventional pre-treatment system involves dosing of chemicals, which requires frequent monitoring of raw water quality, and also involves adjusting the dosage. Besides being cumbersome, there is a lot of time lag involved in carrying out these measures. This calls for pre-treatment ...

  • Experiences with the conventional pretreatment system in the seawater reverse osmosis plant at Kalpakkam

    A 1800 m³/day Seawater Reverse Osmosis (SWRO) plant was commissioned in October 2002 at Kalpakkam, India, as part of the Nuclear Desalination Demonstration Project (NDDP). The conventional pretreatment scheme was adopted consisting of a lamella clarifier, pressurised sand filter, activated carbon filter and cartridge filter. The dosing of pretreatment chemicals, ferrous sulphate and ...

  • Status and prospect of R&D aimed at application of nuclear reactors for seawater desalination in Russia

    In the document "Strategy of Nuclear Power Development in Russia for the First Half of XXI Century", approved by the Government of the RF, seawater desalination is considered as a prospective area of application of the small-sized nuclear power plants (SNPP). Taking into account vast water resources of Russia evenly distributed over the territory of the country, seawater desalination is not a ...

  • 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 ...
