Activated Carbon Filter: Production and Function

active carbon filters blog

Activated carbon can be obtained from various materials such as black coal (anthracite), coconut shells, brown coal, and wood. For financial reasons, activated carbon is usually manufactured using the steam activation process. During this process, the raw material is activated by hot steam under vacuum in a furnace at a temperature of approximately 900 to 1100 °C. The absence of oxygen prevents the material from burning. Instead, the heat causes the internal surface of the material to increase significantly. Activated carbon produced in this way can then be further processed for various purposes.
