Product Profile of Absorbent Granular Activated Carbon

Absorbent granular activated carbon is produced by heating organic matter, such as coal and coconut shell, in the absence of air, which is then crushed into granules. Activated carbon is positively charged and therefore able to remove negative ions from the water such as ozone, chlorine, fluorides and dissolved organic solutes by absorption. Absorbent granular activated carbon must be replaced periodically as it may become saturated and unable to absorb.

Key Features of Absorbent Granular Activated Carbon

• Positively charged and therefore able to remove negative ions from the water such as ozone, chlorine, fluorides and dissolved organic solutes by absorption
• Produced by heating organic matter, such as coal and coconut shell, in the absence of air, which is then crushed into granules
• Must be replaced periodically as it may become saturated and unable to absorb
• Often used as a filter in water treatment systems, where water is directed downwards through a stationary bed of activated carbon, leaving organic material to accumulate at the top of the bed
• Activated carbon is similarly used to lower radon levels in water
