Activated carbon adsorption is most effective for removing what?

Activated carbon adsorption is most effective for removing what?

• A. Heavy metals
• B. Bacteria
• C. Nitrates
• D. Taste and odor compounds

Answer: (D)

Activated carbon adsorption works by attracting and holding certain dissolved compounds onto the carbon’s large, porous surface. It’s especially effective for removing organic molecules that cause taste and odor in water, such as earthy or musty compounds like geosmin and MIB, which readily adhere to the carbon. While it can remove some organic byproducts, it isn’t the primary method for inorganic contaminants or microbes. Heavy metals require ion exchange or precipitation, bacteria are mainly addressed by disinfection and filtration, and nitrates are not readily removed by activated carbon. So, taste and odor compounds are the ones most effectively removed by this process.
