Activated Carbon Water Treatment
You are here:
Granular Carbon Water Treatment
Activated carbon is widely used in water treatment for its excellent adsorption properties. It helps remove contaminants, improve taste and odor, and ensure water safety. Activated carbon is a powder provided in different sizes to meet project requirements.
1. Adsorption of Contaminants
Activated carbon has a highly porous structure and a large surface area, allowing it to trap and hold various impurities through adsorption. This is particularly effective for:
- Organic Compounds: Removes pesticides, herbicides, and industrial chemicals.
- Chlorine & Chloramine: Commonly used in municipal water treatment but can cause taste and odor issues.
- Volatile Organic Compounds (VOCs): Includes PFAS, PFOS, solvents and other pollutants.
- Taste & Odor Compounds: Eliminates compounds like geosmin and methylisoborneol (MIB), which cause musty smells.
- Heavy Metals: Can reduce lead, mercury, and other metals, though effectiveness varies.
2.Types of Activated Carbon Used
- Granular Activated Carbon (GAC): Used in large-scale filtration systems, including municipal water plants and home filtration units.
- Powdered Activated Carbon (PAC): Often added to water in treatment plants to remove contaminants before sedimentation and filtration.
- Activated Carbon Block (ACB): Common in household filters for drinking water purification.
3. Water Treatment Applications
- Municipal Water Treatment: Used to purify drinking water by removing chlorine, disinfection byproducts, and organic pollutants.
- Industrial Water Treatment: Helps remove harmful chemicals from wastewater before discharge.
- Aquariums & Fish Tanks: Maintains clean water by removing toxins and impurities.
- Home Water Filtration: Found in pitcher filters, faucet-mounted filters, and refrigerator water filters.
4. Advantages & Limitations
✅ Advantages
✔ Effective over a wide range of contaminates PFAS, VOSs, Organic Compounds, Metals.
✔ Non-toxic & environmentally friendly, no residual or breakdown products
✔ Effective for in-situ remediation of groundwater without costly excavation.
❌ Limitations
✖ Must contact contaminate contaminant must contact carbon.
✖ Contaminants are adsorbed no destruction of contaminates .
✖ Not effective against all pollutants (salts, minerals, or dissolved inorganic compounds).
