The Hardness and Ash Number of Activated Carbon

E-mail Print PDF


Harness is a measure of the activated carbon’s resistance to attrition. It is an important indicator of activated carbon to maintain its physical integrity and withstand frictional forces imposed by backwashing, etc.

The differences in the hardness of activated carbons mainly depends on the raw material and activity level.The hardness number has a some performance impacts on the life cycle of activated carbon.

 
Ash reduces the overall activity of activated carbon and it reduces the efficiency of reactivation. The metal oxides can leach out of activated carbon resulting in discoloration. Acid/water soluble ash content is more significant than total ash content.


Soluble ash content is very important for aquarists, as ferric oxide which can promote growths of
algal. A carbon with a low soluble ash content should be used for marine, freshwater fish and reef
tanks to avoid heavy metal poisoning and excess plant or algal growth.
