One of the main applications of granular activated carbon is the purification of water. Its function is the retention of organic contaminants and the elimination, by chemical reaction, of the free residual chlorine that remains in the water after the disinfection stage. The removal of free chlorine takes place in the first few centimeters of the carbon bed, so there is no longer any protection against bacterial growth in the rest of the bed. Sooner or later, bacteria can enter from a poorly disinfected influent, or from some point in the effluent pipe. This may happen mainly when there is no water circulation while the equipment is out of service. Bacteria reproduce, and turn the carbon bed into a source of contamination. In order to inhibit bacterial growth, the surface of the carbon is impregnated with 0.1% metallic silver to make carbon bacteriostatic using ionic silver to enable it to bind strongly with carbon surface to make it suitable to function and purify large volumes of water. FEATURES & BENEFITS â?? High efficiency â?? Negligible silver leaching â?? No health hazards to humans â?? No loss in Bacteriostatic property up to 6000 litres water â?? Available in Granular and block form
