Activated Carbon
Activated carbon is a filtration media that is preferred due to its cost-effective advantage. It comes in pelletized, granular and powdered forms derived from materials such as coal,coconut shell and wood, The raw charcoal is superheated to create a large internal pore structure where the organic contaminants can adsorb to. Main applications of Activated carbon are
- Odour control
- Absorption of dissolved organic matter
- Colour removal
- De-Chlorination
- Reduction the level of BOD & COD
The efficiency of a particular carbon will be influenced by the mesh size. Commonly used mere sizes are2Xh, 4x8, 6x12, 8x16, 8x30.
