摘要
A process is disclosed for the production of acidic solutions of activated silica for water treatment. Activated silica is formed during the process of acidifying a sodium silicate solution to below pH 4 with sulfuric acid. A polyvalent metal salt is then added to stabilize the acidified activated silica.
