Working Principle

Filtersorb SP3, by Watch Water, is a Scale Prevention Media which works on the principle of Nucleation Assisted Crystallization (NAC). FilterSorb SP3 media has small nucleation sites on its surface. When the hard water flows over these nucleation sites, the bicarbonates (HCO3) of calcium & magnesium are transformed into micro-crystalline carbonate (CO32-) form. These micro-crystals are very stable, harmless and incapable of forming scale in the water.

The following equation describes the process of Nucleation Assisted Crystallisation that occurs inside the pressure vessel: the pressure vessel:

Filtersorb SP3 antiscale media does not add sodium to water like conventional softeners, while keeping the healthy minerals intact. In the pressure vessel, the equilibrium of the reaction is driven to the right due to the driving force of stable crystal formation. As long as CO2 is being removed the soluble Ca(HCO3)2 converts into insoluble calcium carbonate (CaCO3) crystals.
