Activated Carbon Block (CTO/ACB)
Activated carbon is a form of carbon that has been treated with oxygen to make it very porous, allowing for a larger surface area for chemical reactions to occur.
The carbon absorbs organic materials and Chlorine from the water it comes into contact with.
The Activated Carbon Block is enclosed in a 5-micron filter to catch tiny carbon dust particles that may break off during the filtration.
Many carbons preferentially adsorb small molecules. Iodine number is the most fundamental parameter used to characterize activated carbon performance. It is a measure of activity level (higher number indicates a higher degree of activation) often reported in mg/g (typical range 300–1200 mg/g). It is a measure of the micropore content of the activated carbon (0 to 20 Å, or up to 2 nm) by adsorption of iodine from the solution. It is equivalent to the surface area of carbon between 900 and 1100 m2/g. So essentially the greater the Iodine Number Rating on an Activated Carbon Block, the more effectively the carbon will absorb things such as chlorine and organic molecules.
