A highly
porous adsorbent material, produced by heating organic matter, such as coal,
wood 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 chlorine and dissolved organic solutes by
absorption onto the activated carbon. The coconut shell carbon must be replaced
periodically as it may become saturated and unable to absorb.
One of the most
common applications for activated carbon is the reduction of the undesirable
tastes and odors present in many chlorinated water supplies. Activated carbon
has been successful for many years in the reduction of free chlorine from water
supplies. The end product is clean, fresh water with no objectionable taste or
odor characteristics.
