What does an activated carbon filter remove?
Activated carbon has swept through the modern world and become an essential component in an enormous range of industries, including medical, cosmetic, and agricultural applications. This versatile ingredient is also a crucial component for the best water filtration systems.
How Activated Carbon Filters Work
Carbon’s effectiveness is largely thanks to its incredible surface area.
Physical adsorption is the main way in which activated carbon filters out a given substance. As liquid or air comes into contact with activated carbon, intermolecular forces draw molecules into the millions of pores and pockets on the surface of activated carbon.
Beyond physical adsorption, activated carbon also facilitates chemical reactions. A common example involves chlorine molecules. When chlorine comes into contact with activated carbon, both molecules react to form chloride ions, effectively removing chlorine from water.
The amount of contamination that activated carbon removes from the air or water depends on many different factors, including the type and amount of pollution, the acidity and temperature of the water or air, and how long the water or air spends in contact with the activated carbon.
The specific type of activated carbon also determines the level of filtration provided. Carbon molecules with large holes trap big and heavy molecules such as the ones found in organic chemicals. Small, fine pores pick up smaller and lighter contaminants. Manufacturers of activated carbon often label their products by their adsorption potential.
While activated carbon is safe to ingest, no trace of carbon is left in drinking water after it has been properly and thoroughly treated.
To fully explain every application of activated carbon would take volumes, so we’ve condensed its many uses into several broad categories:
- Medical Applications — Activated carbon is widely used in the medical community to treat overdoses and poisoning. Additionally, activated carbon capsules or tablets can be purchased around the world to alleviate problems like indigestion and diarrhea.
- Industrial Applications — Activated carbon is used in a broad range of industrial and manufacturing contexts. One common industrial application is in metal finishing. Activated carbon is the primary purification agent for removing impurities from metals like nickel.
- Analytical Chemistry Applications — Because of its high adsorption, activated carbon is often used to purify solutions of organic molecules and chemicals. When combined with diatomaceous earth, activated carbon acts as a stationary phase in the low-pressure separation of carbohydrates.
- Agricultural Applications — Activated carbon has risen in popularity with organic farmers and vintners. In livestock production, activated carbon serves as an additive to animal feed, a natural pesticide, a processing aid, and a disinfectant. For winemaking, it is a processing agent that absorbs odor and undesirable color pigments.
- Environmental Applications — Because of its high surface area and adsorption potential, activated carbon serves a wide range of environmental uses. It is useful in groundwater remediation and spill cleanup.
- Cosmetic Applications — Activated carbon is now a popular ingredient in shampoos, toothpaste, and face masks. The same properties that make activated carbon a wonderful filter make it excellent in cosmetic contexts. It traps toxins and contaminants so they can be washed away.
- Distilled Beverage Purification — In the manufacturing of whiskey and vodka, activated carbon filters are sometimes used to remove organic impurities from the beverage. Activated carbon filters out impurities that affect taste, color, and odor without reducing the alcohol content of the drinks.
- Water Purification — Water purification is a major use of activated carbon. Activated carbon filters are used in both large- and small-scale products. They can remove impurities from large-scale, community-wide water systems as well as smaller scale, residential applications.
- Air and Gas Purification — Activated carbon filters out odors, pollutants, and volatile organic compounds (VOCs) from the air by trapping gas molecules and removing them efficiently from circulation. Also, activated carbon can be used to detect and adsorb radon in the air. In gas purification, activated carbon filters remove odors, hydrocarbons, and oil vapors from the air.
- Mercury removal — Mercury is a common and hazardous emission of coal-fired power plants or industries. When infused with halogens or sulfur, activated carbon traps mercury gas and removes it from the air.
- Gas storage — Activated carbon’s porous surface acts like a sponge for many types of gases. Research suggests activated carbon can store fuel gases efficiently in low mass, low volume, and low-pressure environments.
- Space Technology — Activated carbon is an essential component in the life support systems of spacesuits. The activated carbon filter removes trace contaminants from the flow of oxygen to the astronaut, including body odors.
