Nelsen Scale Prevention Systems
FILTERSORB-SP ANTI-SCALING SYSTEMS
Nelsen Scale Prevention Systems features Filtersorb SP
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 SP 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
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-SP Hardness Stabilizer protection were
much cleaner after a short time of use than the control
systems which were cleaned monthly.
Filtersorp SP 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
