Nelsen Scale Prevention Systems features Filtersorb SP3 filter media to first remove the already existing scale from pipes and heat exchanger surfaces (descaling effect) and further to protect the system from future formation of scale (scale protection effect).
Filtersorb SP3 is based on a completely new technology. In this process the chemical structure of scale forming minerals is changed. This technology is so effective that it requires a contact time of only seconds.
The media is used in an up flow system, therefore only an in-out head is needed. The media transforms the dissolved calcium carbonate (temporary hardness) into non-charged, neutral chemical bonds.
These bonds are completely stable and cannot attach to any surfaces. The chemical bonds are rinsed away by the water flow. The size of the bonds is so small (in the range of nano-meters) that they can only be seen with a microscope. Therefore the effect is the same as if the water was free of temporary hardness (calcium carbonate). The chemical structures are heat resistant and do not fall apart.
The media is used to clean pipes from already existing scale and to protect pipes and hardware from scale.
Tests with commercial coffee machines showed that those with FilterSorb-SP3 Hardness Stabilizer protection were much cleaner after a short time of use than the control systems which were cleaned monthly.
Filtersorb SP3 works great in front of RO membranes. It keeps these membranes from clogging with calcium-carbonate. A preexisting membrane’s efficiency is improved after only 10 days if calcium carbonate was the reason for the blocking.
