If you use any of the air purification systems or shop for one you may be familiar with activated carbon filters. With so many air purification systems to choose from, you may wonder how an activated carbon works or what the benefits of using one are. These filters are major combaters of everything from allergens and harsh pollutants to unpleasant tastes and odors. They rely on the process of adsorption to capture and remove impurities. Hence, you can use bulk activated charcoal to control odor. To know more about activated charcoal read below.
What is activated carbon?
Activated carbon is also called activated charcoal is a very useful adsorbent. Due to their high surface area and pore structure, they can be used to purify, and decolorize both liquid and vapor applications. Moreover, bulk activated charcoal are economical adsorbents for many industries such as water purification, food-grade products, industrial gas purification, precious metal recovery mainly for gold.
Types of activated carbon
Different types of activated carbon are suited for various specialized applications. Each grade and size of activated carbon is application-specific. Designing a proper activated carbon filtration system is essential. Also, activated carbon’s physical and chemical characteristics play a significant role in removing contaminants effectively.
Coconut shell-based activated carbon: The high hardness and low dust make these coconut shell carbons particularly attractive for water and critical air applications. It is a renewable and green raw material.
Coal-based activated carbon: The demand for this type is typically high. It is a relatively low-cost filter media for both gas and liquid applications. It has a high surface area characterized by both mesopore and micropores.
Catalytic-based activated carbon: It is used to remove chloramines and hydrogen sulfide from drinking water. It has all the adsorptive characteristics of conventional activated carbons as well as the ability to promote chemical reactions.
Impregnated activated carbon: Surface impregnation chemically modifies through a fine distribution of chemicals. It is a cost-effective way to remove impurities from gas streams which would otherwise not be possible. It is used as a bacteria inhibitor in drinking water filters.
Applications:
Activated carbon or Activated charcoal is used in a wide range of applications for both industrial and residential uses that include drinking water purification, power plant, landfill gas emission, and water treatment. Air purification solutions include VOC removal and odor control. Activated carbon is considered to be the world’s most powerful adsorbent.
