Abstract

Sea water, concentrated by dewatering naturally in the sun, was treated for precipitation of Magnesium Hydroxide by diluted Sodium Hydroxide solution. The Magnesium Hydroxide then is filtered and calcined at 800oC to convert to Magnesium Oxide. By studying affects of parameters: concentration, temperature, stirring rate, … the advandced technological system was determinated, carried out effectively process eliminating Magnesium in the sea water and received saline water for crystallizing purified Sodium salt.
