Silica can exist in water supplies in two main forms. The first of these is "Reactive Silica". Reactive silica is dissolved in water as the bisilicate ion making it a very weak acid. This type of silica can be removed by using specialized ion exchange resins since the silica is dissolved. However, these resins are difficult to regenerate.
