Abstract
Technologies used in water desalination are accompanied by adverse environmental effects. There are several effects to be considered in desalination plants, such as the use of the land, the groundwater, the marine environment, noise pollution and the use of energy. The objectives of this study is the determination of the environmental impacts of Rejected brine in Reverse Osmosis desalination plants, according to the site visits to RO plants in Egypt and the analysis conducted with regards to the brine disposal impacts and thus propose the best solution for impacts handling according to the Egyptian conditions to reach finally to an environmentally friendly desalination plant.
