What is Filtersorb SP3? ✨
FILTERSORB®SP3 is the result of extensive research work along with its undisputable success in the market, worldwide since 2005.
Watch®‘s core motivation for developing this product was to find an alternative to conventional ion exchange based water softeners, reverse osmosis or other chemical based systems that prevent scale.
Recent restrictions placed upon the above mentioned technology lead to an environment friendly, cost effective solution for hard water, Watch®‘s FILTERSORB®SP3. FILTERSORB®SP3 completely takes care of the primary cause of scale forming cations viz. Ca2+ and Mg2+
Working Principle
When the hard water under goes nucleation in the pressure vessel, the calcium bicarbonate Ca(HCO3)2 is transformed into aragonite form of calcium carbonate CaCO3 crystals. These crystals are formed through decomposition and crystallization process, forming very stable harmless crystals.
The following equation describes the reaction that occurs inside the pressure vessel when flow over grains of nucleation.
The name fragment SP(Scale Prevention) 3“ is to indicate this unique transformation of water hardness Ca(HCO3)2 into 3 components viz.
In the pressure vessel, the equilibrium of carbonate species in water is changed, assisted by the driving force of stable crystal formation and therefore the reaction is pushed to the right →. With this technology, as long as CO2 is being removed the soluble Ca(HCO3)2 converts into insoluble calcium carbonate (CaCO3) crystals
The calcium carbonate crystals grow steadily. They are very stable and cannot dissolve (incapable of forming scale) in the water.
Glass grains crystallization sites provide increased nucleation sites for the formation of submicron sized CaCO3 crystals. Hence this amazing process is called NUCLEATION ASSISTED CRYSTALLIZATION or NAC in short.

Do not use where water is microbiologically unsafe or with water of unknown quality without adequate disinfection before or after the unit. System must be maintained according to manufacturer's instructions. Pre-treatment for sediment, Iron, Hydrogen Sulfide, Manganese, hydrocarbons and Copper may be required depending on conditions.Install systems in new facilities with copper pipe after six weeks of water use.
Applications
FILTERSORB® SP3 has proven itself in a variety of applications as an alternative to ion exchange softening or other conventional water treatment methods. The maintenance-free characteristics make it especially suited for Foodservice and Commercial applications where equipment maintenance is often overlooked.

No TDS change
As FILTERSORB® SP3 does not remove or add anything to the water. As no ion-exchange chemistry is used, the TDS of the water remains unchanged before and after the treatment.
No pH change
pH value of the water remains the same. This factor makes the treated water suitable for almost any use where corrosion is concerned.
Minerals Preserved
FILTERSORB® SP3 does not add sodium or any chemicals to the water. It simply reserves the Calcium and Magnesium contents of water, making the treated water arguably the healthiest mineral water available. Both Calcium and Magnesium are quintessential for nervous systems and muscles functionalities. They are indispensable parts in the cell chemistry of the plants and most of the life forms on earth.
De-Scaling
Not only does FILTERSORB® SP3 prevent scale formation, but it also helps to remove the previously formed scales. During the flow some of the micro-bubbles are losing a small amount of CO2, which diffuses rapidly in water and interact with surface scale, especially in closed spaces (pipes, boilers, etc). As a result, the scale which is already present on these surfaces is removed slowly.
Biocidal effect
The NAC process creates the conditions that water dissolved CO2 agglomerate to form micro-bubbles. These CO2 bubbles actively destroy bacterial membranes acting as a biocide. So along with the scale prevention FILTERSORB® SP3 also helps to prevent Biofouling.
FILTERSORB® SP3 has good capacity to absorb Iron, Copper, Manganese, Lead, Zinc etc. Hence in high concentration presence of these contaminants the FILTERSORB® SP3 beads may change color and come to an end of the media life. From studies it‘s also possible that the media might change color due to dye leaching from the container tank made of polyethylene.
In case of any strange color change of the FILTERSORB® SP3 media beads or the treated water is noticed, please contact us with detailed water analysis
