  • 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 ...

  • Repowering and Modification of Grid Connected Reverse Osmosis Desalination Plants

    Currently, there is a strong demand for efficient seawater desalination plants, which can meet the tougher environment regulation and energy saving requirements. From this standpoint the present work was undertaken to include the proposed schemes for repowering and modification of Reverse Osmosis (RO) desalination plants. The model of Modified Desalination Plant (MDP) during sunny periods may be ...


  • Comparison of RO and NF in wastewater reclamation

    Currently, water reuse and reclamation are considered as an essential technology available for alternative water resources with respect to non-potable as well as potable uses. Therefore, lots of studies have been developing various technologies for water reuse, reclamation, and desalination to producing the more reliable and higher quality reclaimed/reused water. In addition, there are several ...

  • 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 ...
