HOW THE FF DESCALER WORKS

FIRST, Calcite or Aragonite:

Without the FF treatment, Calcite crystals (lime scale): In  laboratory tests by placing a drop of water on a glass slide and caUsesng its evaporation, the microscopic observation reveals that the Calcite forms numerous crystals in form of Dendrite, which adhere to the glass. Actually, the lime scales begin to form at the points where the first Calcite crystals adhere to the walls of the pipes and machinery (germination), accumulating in the same way.

With the FF Treatment, Aragonite crystals (soft mud): The same laboratory tests LGAI, accredited by the EC, (Barcelona, File nr.22015382 on 06/06/2002), give a completely different result. It literally states that: “Upon completing the tests mentioned in the results section, we observe that the installation of the Ecological Descaler for Hard Water FLUID FORCE in a pipe from the general distribution network of drinking water, causes a change in the structure of the Calcium Carbonate. Before putting the FF descaler in place, the crystalline structure is mainly in Calcite form and less in the form of Aragonite; after placing it only the crystalline structure of Aragonite may be observed.”

ConclUseson: a) A preventive effect is seen (crystal formation of Aragonite, soft mud evacuated by the running water). b) Calcite and the inlaid Magnesium Carbonate formed prior to treatment are dissolved by means of a slow and progressive process. These tests have been done Usesng different magnets, different magnetic poles, waters flowing at different speeds and temperatures, showing that the velocity of the water flowing through the magnetic field is the most important factor which generates the necessary kinetic energy, without which the magnetic treatment would not cause any effect. Also, it has been demonstrated that the water has a magnetic memory, which maintains the effects of the treatment during a minimum of 2 days even if water does not circulate (tanks, storage cells, etc.).

Other Characteristics

Refractive indices of 1.49 and 1.66 caUsesng a significant double refraction effect (when a clear crystal is placed on a single line, two lines can then be observed), effervesces easily with dilute acids and may be fluorescent, phosphorescent, thermoluminescent and triboluminscent. Aragonite effervesces easily in cold dilute Hydrochloric Acid, is strongly bi-refringent, is fluorescent and its refractive index is 1.7.

Appearance

In good size crystals, 2 main patterns: a) In very acute scalahedrons (dog’s tooth). b) In very obtuse scalahedrons crowning the bases of the trigonales prisms (nail head). c) Also very typical rhombohedrons like exfoliation products; in  massive spastic forms, fibrous, columns, stalactites, granular and dusty. Frequent macles. In simple rombohedric crystals or with multiple macles giving an aspect of a hexagonal prism or stalactites.

Chemical Composition

Contains 56,03% of CaO and 43,97% of CO2. The Ca may be substituted by Mn, Fe and in less measures Sr, Co, Zn, Ba and Pb. The same theoretic composition as Calcite.  It’s a polymorph of CaCO3 unstable in atmospheric conditions.  It contains the isomorphic substitutions Ba, Sr, Pb and Zn. Soluble in hydrochloric acid.

Field Indicators

Hardness (3), perfect exfoliation (rhombohedric), clear in color and a glassy shine, bi-refringency and reacts with it to  cold Hydrochloric Acid. Crystalline habit, one singular plane of division and reaction to cold. Hydrochloric Acid.

         SECOND: The Ions don’t adhere to piping and machinery.  The electrical phenomena caused by FF allow the water to increase its capacity to maintain a greater number of Ions present in the dissolution. 

THIRD: FF decreases the pH and the superficial tension of the water, reducing the risk of scale.
