The AquaPur tank is used for storing drinking water for your home. AquaPur uses silver-ion technology developed by Valrom to prevent the development of microflora in the storage tank. It requires minimal maintenance operations and can provide safer, cleaner water for long periods. The interaction stages are as follows: the active layer is exposed to the immersion medium at the interface with the liquid. Ag+ ions diffuse into the immersion medium. The concentration gradient increases and equilibrium is established at a level of approx. 23 ppm (parts per million). The time to reach the equilibrium concentration is approx. 2448 hours, depending on the amount of liquid and the recirculation speed. Microorganisms are exposed to contact with Ag. Ag ions interfere with the microorganisms’ reproduction mechanism, inhibiting their development. – other Ag+ ions are released as they are consumed. This product is treated with silver-based biocides and has been tested in accordance with ISO 22196:2011.
