Water Treatment: Catalytic Carbon


Catalytic carbon is a type of filter media that removes select contaminants from drinking water.

In this guide, we’ve answered the question, “What is catalytic carbon?” You’ll learn how catalytic carbon filters are made, how they differ from standard activated carbon filters, what they remove, the types of systems they’re used in, and more.

A catalytic carbon filter has an altered electronic structure that enhances its catalytic activity, enabling it to remove more contaminants (like chlorine and hydrogen sulfide).

What Is Catalytic Carbon Made From?

The activated carbon itself comes from various natural sources – typically coconut shell, but sometimes wood, coal, or peat. These materials are processed, giving them a large surface area and a highly porous structure.

Catalytic carbon works by adsorbing various contaminants and delivering a catalytic reaction that breaks down other impurities.

How Does Catalytic Carbon Work?

A catalytic carbon filter has an activated carbon media with a large surface area and hundreds of tiny pores. When water flows through the filter, contaminants like chlorine come into contact with its carbon surface.


The carbon’s porous structure allows it to trap or adsorb impurities on its surface, while water molecules can pass through the pores and exit the filter on the other side.

The catalyst incorporated into an activated carbon filter enhances its ability to target and break down other impurities. During a catalytic reaction, CC converts various contaminants into harmless ions.
