Silica Removal by Ion-Exchange

Ionic Silica is a very weak acid that is why it is removed by a Hydroxide-based cycle almost completely. Silica Ion-Exchange systems are normally composed of mineral tanks and since we use strong base chemical to regenerate the resin in this system so we need to have corrosion resistant tanks such as (FRP tanks and Rubber-lined Steel tanks).
