What is Activated Carbon?
Activated Carbon History
The history of activated carbon can be traced far back to 1550 B.C.; at the time of ancient Egypt, activated carbon was used as remedies to treat poisonings. Since then, in addition to medical use, powdered activated carbon was mainly used for de-colorization at sweetener factories.
In the 20th century, during World War I, coconut shells were used as raw materials to produce granular activated carbon for military respirators. With the development of new activated carbon products, systems, and services, the production capacity of activated carbon steadily increased worldwide because of its convenience and competitive advantages in many applications.
Modern industrial development and urban congestion created environmental issues worldwide. Protecting the environment is vital to our quality of lives, which depends on the purity of air and water. Demands towards activated carbon have increased for advanced water treatment and purification of air by removing impurities such as dioxin.
