Abstract
PURPOSE: To remove silicic acid in water, which has been recognized as very hard to work, easily and with high efficiency by bringing a silicic acid-containing water into contact with activated alumina particles in the presence of a metal ion.
CONSTITUTION: The water containing silicic acid is regulated its alkalinity by the addition of an alkali if its alkalinity is deficient, and also its hyrolyzable metal ion content is controlled, if it is deficient, by the addition of a hydrolyzable metal ion, e.g., aluminium ion, magnesium ion, iron ion, etc. Under these conditions, the silicic acid-containing water is brought into contact with activated alumina particles. The alkalis used include caustic soda, caustic potash, aqueous ammonia, alkali aluminates, etc.
