Carbón activado impregnado de plata

Silver Impregnated Activated Carbon is a functional enhancement that results in uniform deposition of Ag – as an element of Ag or Ag – on both inner and outer surfaces of high quality active carbon substrates, usually from coir, coal or wood based raw materials. Dipping is performed by means of a controlled wet CVD or ion-exchange technology, which guarantees an even distribution of silver grains across the carbon’s pore net at accurately calibrated loading levels. The final product maintains the complete absorption capacity of the basic active carbon and also acquires a strong, embedded antibacterial function.

Silver is used to convert active carbon from pure physical adsorber to dual action filter. Silver ions (Ag, Ca) emitted from the carbon surface are highly toxic to a wide range of organisms — including bacteria, fungi, and some viruses — that damage the integrity of the cell’s membrane and suppress the enzyme metabolism. This antibacterial and germicidal action solves one of the main shortcomings of standard active carbon in water-processing applications: the risk of bacteria colonisation and re-growth inside the carbon bed. Silver impregnated active carbon can preserve filtration sanitation by inhibiting the growth of microorganisms at its source, thereby preserving the treatment water quality and prolonging the useful lifetime of the filter medium without requiring additional chemical sterilization.
