  1. DESALINATION THREAT TO THE GULF

  2. Prof. Hersh ChadhaOPM (Harvard) ARPS What is desalination and brine? • Seawater is pumped into the plant and pre-treated to meet water quality requirements. • The pre-treated water enters the Desalination unit and is divided into a highly pure product (drinking water) and waste water, commonly called brine. • This by-product of the desalination process is concentrated salt water containing a mixture of chemicals used during plant operation and is pumped back into the sea.

  6. Prof. Hersh ChadhaOPM (Harvard) ARPS Some Facts of Desalination in the Arabian Gulf • Seawater desalinated daily from the Arabian Gulf – 12 Million Cubic metres • Seawater desalinated annually from the Arabian Gulf – 4.38 Billion Cubic metres • Seawater desalinated daily from the UAE – 6 Million Cubic metres • Number of Bottles (1.5 litres capacity) of Water desalinated daily in the UAE – 4 Billion • Desalination Plants in the Arabian Gulf - 120
