Centrifugal air classifiers use secondary air flow to separate particles ranging from 100 microns to 20 microns. This air flow, as well as the diameter of the coarse-particles opening, is adjustable – for a clear, accurate cut point. Secondary air flow is also crucial in the removal of near-size particles.

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.
