Activated Carbon is useful in drinking water treatment because it acts as an adsorbent. Carbon filter is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities from a fluid using adsorption.
⦁ Activated carbon water treatment is basically used for two water treatment purposes and each work in totally different ways

Chlorine Removal:-
Activated Carbon catalyzes removal of free chlorine with little consumption or degradation of the carbon during the process.
Removal of Organic Matter:-
As water passes through an activated carbon filter, organic particles and chemicals are trapped inside through a process known “adsorption”.
There are Two types of Activated Carbon Filter:-

1. Granules Activated Carbon: – It is used in Purification of Drinking Water.
2. Powdered Activated Carbon: – It is used in Waste Water Industries.
