A very absorbent form of finely powdered carbon; used in purifying gases, and as an antidote for many poisons
A form of carbon specially formulated for filtration Carbon is good for removing a large number of toxins and other unwanted substances from aquarium water it is especially useful for clearing or "polishing" cloudy water One problem with carbon is that is can release phosphate into the water, which stimulated algae growth
Granulated active carbon used to remove tastes, odor, chlorine, chloramines and some organics from water Carbon is the preferred treatment for a large percentage of water contaminants
A highly adsorbent form of carbon used to remove odors and toxic substances from liquid or gaseous emissions In waste treatment, it is used to remove dissolved organic matter from waste drinking water It is also used in motor vehicle evaporative control systems
Pure carbon heated to promote active sites which can adsorb pollutants, used in some water treatment systems to remove certain organic chemicals and radon gas
Available in granules (GAC) or powder Granules are usually more practical for commercial use Removes negative ions from the water (such as ozone, chlorine, fluorides etc ) Once used it can be recharged by heating to 900oC Not generally financially viable for commercial systems Sometimes used in small hatcheries, especially where mains water is being used and chlorine and other chemicals added to the water must be removed
Carbon that has a highly porous structure to provide filtration of odors and extremely fine particulates
A highly absorbent powdered or granular carbon used for purification by adsorption
Adsorptive particles or granules of carbon usually obtained by heating carbon (such as wood) These particles or granules have a high capacity to selectively remove certain trace and soluble materials from water
A highly adsorbent form of carbon used to remove odors and toxic substances from liquid or gaseous emissions In waste treatment it is used to remove dissolved organic matter from waste water It is also used in motor vehicle evaporative control systems
a powdered or granular carbon that is highly absorbent, which may be used to remove organic vapors and odors
chemically treated and heated carbon which has the ability to absorb gold
powdered or granular carbon used for purifying by adsorption; given orally (as a slurry) it is an antidote for some kinds of poisons
A granular material usually produced by the roasting of cellulose base substances, such as wood or coconut shells, in the absence of air It has a very porous structure and is used in water conditioning as an adsorbent for organic matter and certain dissolved gases Sometimes called "activated charcoal "
A material made from burnt wood that is used to remove organic solutes, such as pesticides, and some inorganic solutes, such as chlorine, from water Dissolved organic solutes are removed from the water by absorption onto the activated carbon The activated carbon must be periodically replaced when it becomes saturated and unable to absorb any more solutes Activated carbon is not effective in removing heavy metals, such as lead and salts, which make water hard
