Answer / rao dv. The silica in ionic form (also reactive silica) is removed by strong base anion exchanger effectively. The traces coming out from DM PLANT and colloidal silica which is not removed by SBA EXCHANGER will be carried to the boiler drum. At the boiler operational pressures, the colloidal form will be converted to reactive form.

Colloidal Minerals: Unnecessary and Potentially Hazardous

Minerals are composed of elements. For example, the mineral silica is composed of the elements silicon and oxygen. Colloidal mineral promoters use these terms interchangibly. They also employ the misnomer "metallic minerals" to distinguish (supposedly ineffective) standard supplement products from their "plantbased" colloidal minerals.
