Abstract
PURPOSE: To efficiently obtain fresh water by adding cement to salts-contg. water such as seawater or underground water to remove the salts in the water.
CONSTITUTION: Cement as a desalting agent is added to salts-contg. water such as seawater or underground water to carry out desalination. For example, Portland cement contains the components such as SiO2, Al2O3, Fe2O3, CaO, MgO, SO3 etc. and reacts with salts in seawater or the like to flocculate them and perform pH adjustment. Thus, cement shows a useful effect as a desalting agent for seawater, etc. By carrying out secondary treatment using cement in combination with other auxiliary, fresh water sufficiently usable as industrial water is obtd.
