Method for treating water to reduce dissolved silica content thereof

Process for treating water in order to reduce its dissolved silica content, characterized in that it comprises at least one step of adsorbing said dissolved silica, consisting in passing said water in a reactor containing an adsorbent particulate material consisting of particles of iron (III) hydroxide and/or iron (III) oxyhydroxide; and at least one step of regenerating the adsorption capacity of said particulate material, consisting in contacting said particulate material with a base and at least one chloride. 用于处理水以降低其溶解二氧化硅含量的方法，其特征在于，该方法包括至少一个吸附所述溶解二氧化硅的步骤，该步骤在于使所述水在容纳由氢氧化铁(III)和/或羟基氧化铁(III)的颗粒组成的吸附性颗粒材料的反应器中通过；以及至少一个再生所述颗粒材料的吸附能力的步骤，该步骤在于使所述颗粒材料与碱和至少一种氯化物接触。
