“Activated carbon is porous, inexpensive, and easy to use as an adsorbent, providing a large surface area for contaminant removal. It has more usable surface area per gram than any other material available for physical adsorption. In fact, a teaspoon of activated carbon has more surface area than a football field.” – Henry Nowicki
History of Activated Carbon for Industrial Use
The first uses of activated charcoal date back to the Egyptians, who utilized its adsorbent properties for medicinal purposes and to purify oils. But it was actually charcoal, activated charcoal in the modern sense of the term, which only appeared in the late 19th century.
Activated carbon is considered the world’s most powerful absorbent. It’s environmentally friendly thanks to its regenerative capacity.
What is activated carbon?
Activated carbon (also called activated charcoal or activated carbon) is a very useful adsorbent. Thanks to its large surface area, porous structure (micro, meso, and macro), and high surface reactivity, it can be used to purify, dechlorinate, deodorize, and decolorize both liquid and vapor applications. In addition, activated carbons are economical adsorbents for various industries, such as water purification, food-grade products, cosmetics, automotive applications, industrial gas purification, petroleum, and the recovery of precious metals, primarily gold. The base materials for activated carbons are coconut shells, charcoal, or wood.
Types of activated carbon
There are different types of activated carbon suitable for various specialized applications.
Each grade and size of activated carbon is specific to each application. Selecting the correct activated carbon and mesh size depends on the application and the contaminants to be removed.
Typical applications
Removal of volatile organic compounds such as benzene, TCE, and PCE. Hydrogen sulfide (H2S) and off-gas removal. Impregnated activated carbon is used as a bacteria inhibitor in drinking water filters. Removal of taste- and odor-causing compounds such as MIB and geosmin. Gold recovery. Chlorine and chloramine removal. It is important to design a suitable activated carbon filtration system with adequate contact time, pressure drop, and vessel size. Furthermore, the physical and chemical characteristics of activated carbon play a critical role in effective contaminant removal. Therefore, material testing is essential.
