FILTERSORB® SP3 Scale Prevention method:

Nucleation Assisted Crystallization (NAC) Technology. This is a directed crystallization process where continuous catalytic conversion of Carbonate water hardness into non-soluble sub-micron crystals takes place.

When the hard water under goes nucleation in the pressure vessel, the calcium bicarbonate Ca(HCO₃)₂ is transformed in 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.

Ca(HCO₃)₂ → CaCO₃+ CO₂ + H₂O

 

• The name fragment "SP3(Scale Prevention)" is to indicate this unique transformation of water hardness Ca(HCO₃)₂ into 3 components viz. 1. CaCO₃ (micro-crystals) 2. CO₂ (colloid) and 3. H₂O (pure)

In the pressure vessel, the equilibrium of carbonate species in water is shifted, 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.

Once formed and detached from the surface of FILTERSORB® SP3 media beads, the crystals will not adhere to any other surfaces, even in the case of hot water applications. The crystals cannot form scale because of its stable molecular structure and neutral surface electro potentiality.

Nucleation Assisted Crystallization is the basis of reliable Scale Prevention capability of FILTERSORB® SP3.

The transformation of water hardness takes place in the following steps:
1. Continuous transformation of water hardness makes the immediate crystal growth possible with unidirectional chemical equilibrium viz. Ca(HCO₃)₂ → CaCO₃ + CO₂ + H₂O

As CO₂ leaves fast the right hand direction of the equation is preserved.

2. The crystals developing on the surface of the FILTERSORB® SP3 bead, grow rapidly and nucleates
3. After a certain period of time the micro-emulsion of CO₂ and CaCO₃ forms colloid particle and leaves the media bead surface in neutral form. The average dimension of CaCO₃ crystal coated globules ranges in sub micro-meter scale. The noted reaction time is normally around 5 seconds.

 

Micro Crystals and Colloid CO₂ : The story behind amazing pH stabilization of FILTERSORB® SP3 treated water

Influence of formed CaCO₃ as pH balancing factor:
The reaction: Ca(HCO₃)₂ → CaCO₃ + CO₂ + H₂O is unidirectional while SP3 is transforming the hardness into water insoluble crystals.

• In nucleation assisted crystallization process formed CO₂ leaves as colloid gas and is used as the template by the rapidly growing crystals in the nucleation site.
• Formed CO₂ micro-bubbles exists in colloid form and thus does not form carbonic acid to dissolve back the calcium/magnesium crystals
• Hence, the reverse reaction of CO₂ with water forming Carbonic Acid is not possible and the pH stability is maintained. In fact every excess CaCO₃ crystals are buffering any carbonic acid left over. (See Illustrated Presentation)

Note: 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.

Special Information: 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.
