Silica is a mineral, meaning it is made up of atoms that are arranged in a specific pattern.
Webpected that activated silica will make the process less critical. The point of silica addition must also be studied. In some waters the silica should be added ahead of the alum, and, in others, subsequent to it. The proper point must be determined for each water. At present, however, it appears that silica application usually follows alum addition. WebAddition of a mineral acid destabilizes the silicate solution forcing the silicate polymers to form colloidal silica particles, known as a silica hydrosol. The size of the colloidal particles, typically 1.5 to 2.0 nm, depends on silica concentration, electrolyte level, amount of excess acid and temperature.
