<p>A method of desalinating seawater, comprising the acidity adjusting step of mixing an oxidizing agent in seawater to thereby attain adjustment to an acidic water of 2 or below pH value; the reduction adjusting step of mixing a reducing agent in the acidic water after the acidity adjusting step to thereby attain adjustment to a reduced water of 11 or above pH value; the separation step of passing the reduced water after the reduction adjusting step through a filtration layer of rice husk smoked charcoal to thereby separate any solid matter contained in the reduced water; and the filtration step of passing the reduced water devoid of solid matter after the separation step through an adsorption filtration layer of rice husk smoked charcoal mixed with multiple ore particulates of zeolite, Bakuhanseki stone, tourmaline, basalt, etc. to thereby attain adsorption removal of substances resulting from breakdown of salts contained in the reduced water. Accordingly, a seawater desalinating method capable of removing salts contained in seawater at low cost is realized by a chemicophysical treatment of seawater combining a chemical treatment composed of the acidity adjusting step and the reduction adjusting step with a physical treatment composed of the separation step employing a filtration layer of rice husk smoked charcoal and the filtration step employing an adsorption filtration layer.</p> |
