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.
