Activated carbon is used in many residential water filtration products, but it can appear in several forms. Granular activated carbon, carbon block cartridges, and bulk activated carbon media each have different physical formats and applications. Understanding these options can make filter selection easier.
1. What Is Activated Carbon?
Activated carbon is a porous carbon-based filtration medium used in various water treatment applications. It can be manufactured from different source materials and processed into different forms.
The type and construction of the carbon should be considered when comparing filtration products.
2. Granular Activated Carbon
Granular activated carbon, or GAC, consists of individual carbon granules. GAC can be placed inside a dedicated cartridge or used as loose media in certain filtration equipment.
The amount and grade of media can vary by product.
3. Carbon Block Cartridges
Carbon block filters use activated carbon formed into a cartridge structure. This is different from a cartridge filled with loose granules.
Carbon block products are available in various sizes and formulations, so compatibility should be confirmed before replacement.
4. Bulk Activated Carbon Media
Some filtration systems use bulk activated carbon rather than a finished cartridge. Products may be sold by weight, allowing the media to be loaded into a suitable filter vessel.
Bulk media should only be used in equipment designed to accommodate that type of material.
5. Choosing the Appropriate Format
Consider whether the existing system requires a cartridge or loose media. Then compare the carbon type, product specifications, system capacity, and installation requirements.
The source material, such as coconut shell carbon, may also be listed as part of the product description, but it should be evaluated alongside the complete product specification.
Conclusion
Activated carbon is available in several forms, including GAC, carbon block cartridges, and bulk media. Choosing between them depends on the existing filtration equipment and intended application. Always match the media format and specifications to the system rather than selecting by material name alone.
