Granular activated carbon, eminently microporous and, therefore, indicated for water purification.

Adsorption is a process where a solid is used to remove a soluble substance from water. In this process the activated carbon is the solid. Activated carbon is produced specifically to reach a very large internal surface area (between 500 – 1500 m 2 /g). This large internal surface makes the carbon have an ideal adsorption. Activated carbon comes in two variations: Powdered Activated Carbon (PAC) and Granular Activated Carbon (GAC). The GAC version is mostly used in water treatment.

• The raw material is of plant origin, and therefore does not contain the heavy metals and other contaminants typically present in mineral coals.
• When thermally activated, no chemical compounds are used that can leave residues in the coal.
• Coal has the pore diameter that most efficiently absorbs low molecular weight organic pollutants, which are usually the most harmful to humans.
• Elimination of odors and flavors in water.
