Everything You Need To Know About Silica In Your Water
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.
