Abstract: PURPOSE: A producing method of seawater magnesia using concentrated seawater is provided to produce seawater magnesia with high productivity and simple processes by using a solid-liquid separator and the concentrated seawater obtained from a seawater desalination process. CONSTITUTION: A producing method of seawater magnesia using concentrated seawater comprises the following steps: decarbonating the concentrated seawater obtained from a seawater desalination process; precipitating magnesium hydroxide by adding a precipitation agent to supernatant of the decarbonated concentrated seawater; separating and filtering magnesium hydroxide from the supernatant using a solid-liquid separator; and plasticizing the separated magnesium hydroxide. The seawater desalination process is a reverse osmotic pressure type seawater desalination process. The precipitation agent is one or more selected from Ca (OH)2 or NaOH. The producing method of seawater magnesia processes the supernatant without magnesium hydroxide with a nanofilter into concentrated water and processed water.
