Activated Carbon Filters

Activated Carbon Filters

Activated carbon filters contain granular activated carbon. Thanks to the physico-chemical treatment process that takes place in the activated carbon mineral, free chlorine, organic matter, odor, color and taste are removed from the water. While free chlorine is removed by the reaction of chlorine compounds with the activated carbon surface, the organic molecules are removed by being held in the porous structure of the activated carbon material.

Depending on the purpose of use in activated carbon filtration systems, coconut-based or coal-based carbon minerals may be preferred. Coconut-based activated carbon is preferred for drinking water applications where microorganismal growth is not desired. The use of coal-based activated carbon is common in the supply of process water for industrial purposes.

Activated carbon filters are also used for dechlorination (chlorine removal) prior to reverse osmosis demineralization systems.
