Activated Carbon 101

Activated Carbon was first known to treat water over 2,000 years ago. However, it was first produced commercially at the beginning of the 20th century and was only available in powder form. Initially, activated carbon was mainly used to decolorize sugar and then, from 1930, it was used for water treatment to remove taste and odor.
