Aragon cartridges

Aragon filtering material is a unique polymer of combined action, ensuring microglobular purification. It retains the finest mechanical particles and removes dissolved chemical impurities owing to its complex structure and to the sorption and ion-exchange mechanism. According to the Conclusion of the Pasteur Institute, Aragon filtering material completely removes from water all bacteria and viruses including hepatitis A viruses, noroviruses, and rotaviruses. Silver in the metallic form, incorporated into the polymer structure, suppresses reproduction of the filtered-off bacteria and viruses.



  • Aragon cartridge itself prompts when it becomes necessary to replace or regenerate it, owing to self-indication of the end of the operation life: sharp decrease in the pure water flow rate.
  • Aragon cartridge can be regenerated at home, which significantly prolongs its operation life. The complete regeneration cycle involves treatment to remove mechanical impurities and iron and restoration of ion-exchange properties. This is very important, because problems of water treatment are not restricted to scale control.
  • Aragon cartridge has an antidischarge property: The filtered-off contaminants can never be discharged into the purified water owing to a complex labyrinth structure of the filtering material.
  • The amount of water that can be purified with Aragon cartridge is 7000 l (with repeated regenerations, 25000 l). It is intended for scale removal by the mechanisms of removal of hardness salts and of quasi-softening.
  • Aragon material allows choice of the filter adequate to the natural water type of the given region. For soft water, Aragon S; for hard water, Aragon H, Aragon 2

Quasi-softening effect of Aragon cartridge

A unique feature of Aragon cartridges is that, with hard water, two mechanisms of scale elimination operate simultaneously: removal of hardness salts by the classical ion-exchange mechanism and the quasi-softening effect (patent 2004138606/15).

 

What is the quasi-softening effect and what are its unique features?

 

In common water, calcium carbonate is present in the form of calcite. On heating, it precipitates to form a dense deposit (scale). Calcite crystals have a rectangular shape. Therefore, they tightly adhere to each other and to surrounding surfaces like small bricks. However, calcium carbonate also exists in another modification, aragonite, with rhombic crystal shape. Common water contains virtually no aragonite. Rhombic crystals of aragonite tend to agglutinate and adhere to surfaces to a considerably lesser extent than do rectangular crystals of common calcite.

 

As a result, friable aragonite deposit is readily broken and washed away with water flow. Appearance of aragonite in water results in breakdown of the already formed scale, because aragonite crystals become centers of recrystallization. This is the essence of the quasi-softening effect exerted by Aragon cartridge. The quasi-softening effect was theoretically substantiated by researchers of the Vienna State University and was confirmed on the quantitative level at the Fedorovskii Russian Research Institute of Mineral Resources.

 

The essence of this process is as follows: Due to Coulomb attraction forces, dipoles of water molecules and ions of hardness salts form cluster structures. These are relatively large metastable formations. As water flows through the porous structure of the Aragon material, the pressure that steadily grows owing to channel narrowing compresses and breaks down the clusters. The salts get free of the shell of water molecules and interact with the filtering material. Its specific properties create conditions for the formation from the dissolved carbonates of carbon dioxide which is sorbed by channel walls. At the exit from the filtering material, the pressure grows to a maximum and then sharply decreases to zero. As a result, carbon dioxide is intensely released, and it rapidly volatilizes from water.

 

The same phenomenon can be observed when opening a bottle with carbonated water. The release of carbon dioxide increases pH of water, creating favorable conditions for the formation of calcium carbonates in the form of aragonite, which saturates the purified water.

 

The formation of the aragonite structure of hardness salts was confirmed experimentally. The appearance of aragonite can be seen both under a microscope at a large magnification and in X-ray diffraction patterns taken at the Russian Research Institute of Mineral Resources.

 

Quantitative data of X-ray phase analysis show that the content of the aragonite form of calcium carbonate in water after passing through Aragon material increases considerably (by a factor of 8–10).

Aragon S

 

Aragon S cartridge is the calcium-saturated modification of Aragon material for soft water.


Aragon S fully removes from water harmful impurities, with deficient calcium and magnesium salts preserved.


Aragon H

 

Aragon H cartridge is the modification intended for regions with hard water. Aragon H removes from water excessive hardness salts, iron, and other harmful impurities. The amount of hardness salts decreases to the level recommended by physicians. Owing to the quasi-softening effect, the calcium salts remaining in water are mainly in the aragonite form.


Aragon 2

 

Aragon 2 cartridge is a composite material synthesized by the unique technology developed by the Geyser Company for compounding with an ion-exchange resin.
The approximate ratio of Aragon polymer to the ion-exchange resin is 1 : 1. This allowed the operation life of Aragon 2 cartridge with respect to removal of hardness salts to be increased by a factor of 12–15 relative to Aragon H.


The presence of an ion-exchange resin in the filtering material considerably increases the operating life and the efficiency of removal of such impurities harmful for human as manganese, iron (including colloidal iron), and heavy metals (cadmium, lead, etc.). The quasi-softening effect mechanism operates simultaneously.
