Activated carbon, a porous material made from carbon-rich sources like coconut shells, is commonly used in water treatment for its ability to adsorb a variety of contaminants, including organic compounds, chlorine, and heavy metals. This makes it essential for improving water quality by removing impurities and improving taste and odor.
How It Works: Activated carbon adsorbs pollutants through physical and chemical adsorption. It works by trapping contaminants in its pores, offering a large surface area for removal.
Types:
- Granular Activated Carbon (GAC) – Used in large-scale filtration systems.
- Powdered Activated Carbon (PAC) – Effective for quick adsorption in slurry form.
- Extruded Activated Carbon (EAC) – Cylindrical pellets used in air and water treatment.
Applications:
- Water Treatment: Removes organic compounds, chlorine, and VOCs.
- Wastewater Treatment: Used in industrial applications.
- Aquarium & Pool Treatment: Ensures clean water.
- Air Purification: Removes gases and odors.
Advantages:
- High adsorption capacity
- Cost-effective and versatile
- Improves water taste and odor
- Can be regenerated
Limitations:
- Less effective at removing heavy metals and inorganic contaminants
- Requires regular replacement or regeneration
In summary, activated carbon is an efficient and affordable solution for water purification, improving water quality by removing a wide range of contaminants.
