Granular Activated Carbon

Granular Activated Carbon

Granular Activated Carbon has a relatively larger particle size compared to powdered Activated Carbon and consequently, presents a smaller external surface. Diffusion of the adsorbate is thus an important factor. These carbons are therefore preferred for all absorption of gases and vapors as their rate of diffusion are faster. Granulated carbons are used for water treatment, deodorization and separation of components of flow system and is also used in rapid mix basins. GAC can be either in granular or extruded form.

FAQs Granular Activated Carbon

1. What is granular activated carbon used for?
Granular activated carbon is primarily used for water and air filtration systems, including odor removal, and in industrial processes that require high adsorption capacity.
2. How is granular activated carbon different from powdered activated carbon?
Granular activated carbon has larger particles and is designed for applications that require slower flow rates, making it ideal for water and air purification systems.
3. Can granular activated carbon be used for home water filtration?
Yes, it is commonly used in home water filters, providing effective removal of chlorine, organic compounds, and other contaminants.
4. How often should granular activated carbon be replaced?
Replacement frequency depends on usage and the level of contamination in the air or water. Typically, it needs replacing every 3-6 months for residential systems.
5. Can granular activated carbon be regenerated for reuse?
Yes, granular activated carbon can be regenerated in some applications, usually through heat or chemical treatment, though it depends on the contamination level.

Granular activated carbon is widely recognized for its effectiveness in removing contaminants from air, water, and industrial fluids. Its larger particle size allows for a slower flow rate, making it ideal for applications where extended contact time with the adsorbent material is required. Granular activated carbon is commonly used in home water filtration systems, industrial water treatment plants, and air purification systems to remove organic compounds, chlorine, and volatile organic compounds (VOCs). With its high adsorption capacity, granular activated carbon offers long-lasting performance and is highly durable. Western Chemical’s granular activated carbon provides a cost-effective solution for businesses and homeowners alike who need efficient and reliable filtration.
