A method for manufacturing ceramic bails for water treatment capable of exerting microbicidal activity in water and solution is provided. The method includes producing a first composition by dissolving borax (Na<SUB>2</SUB>B<SUB>4</SUB>O<SUB>7</SUB>.10H<SUB>2</SUB>O) and copper sulfate (CuSO<SUB>4</SUB>.5H<SUB>2</SUB>O) in an equivalent ratio of 1:1 to water, and drying the solution to produce a first composition, producing a second composition by adding silica to a first mixture of nitric acid and silver mixed in an equivalent ratio of 1:1 while heating the first mixture, adding more than 3 weight percents of the first composition to 200 weight percents of distilled water based on 100 weight percents of a ceramic ball while heating the distilled water, adding more than 8 weight percents of the second composition to a second mixture of the first composition and the distilled water when a total weight of the second mixture is reduced by a half, and drying the second mixture; and dehydrating the second mixture at a temperature of 400° C. to 500° C. |
