Granular Activated Carbon media and activated carbon cartridges are on of the most common styles of carbon filters in the market. Activated carbon absorbs chemicals such as chlorine fairly easy. This type of carbon can also reduce the amount of other chemicals to an extent, at a reduced capacity.
Catalytic Carbon is becomming a popular choice fore removing/reducing chlorine and other contaminants from the water. Vivekanand Gaur of the WQA explains “To enhance the catalytic activity of carbon, the surface is modified by a chemical process in which the electronic structure of the carbon is altered in such a manner that the resulting carbon offers enhanced catalytic capability”. This process results in catalytic carbon. Catalytic carbon has several advantages over tradational carbon such as better chlorine/chloramines capacity.
Catalytic Activated Carbon
|Chlorine Reduction/Removal||Higher Capacity for Chlorine Reduction/Removal|
|Limited Reduction of THMs, VOCs and Chloramines||Better Reduction of THMs, VOCs and Chloramines|
|Most Common In Cartridge Filters||Only Used in Special Carbon Filters|
|Reduction/Removal of Bad Tastes and Odours||Reduction/Removal of Bad Tastes and Odours|
|Limited Reduction of Hydrogen Sulfide||Better Reduction of Hydrogen Sulfide|
