  • 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, ...

  • 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 ...

  • 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%. ...

  • 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 ...

  • A bio-thermic seawater desalination system using halophytes

    A bio-thermic seawater desalination system using halophytes was developed and successfully tested. A greenhouse as part of a test rig, with different sorts of mangroves, was installed. Measurements showed promising results concerning fresh water relative yielding rates up to 1.4 kg/h/m² (leaf surface)/m² (heat exchanger surface). In addition to experimental results, possible future ...
