Silica Removal Filters
Silica present in water varies form less than 1 ppm to over 100 ppm. It forms a very hard scale in boilers and form deposits on turbine blades. In modern high pressure boilers, it is reduced to as low as 10ppb level. Silica is present in water in colloidal form and ionic form. Colloidal silica can be removed by dosing poly electrodes in the water before clarification. Only the ionic silica is removed in anion exchanger mixed bed exchanger.
