Coconut shell activated carbon has mainly pores on a micropore scale. Almost 85-90% of the coconut shell surface is made up of these micropores. These small pores match the size of contaminants in drinking water and are therefore very effective in trapping them.
Unlike, peat and wood charcoal are predominantly macro-sized pores that match the size of larger molecules.
The superiority of micropores in coconut carbon gives it a denser and more durable structure that provides good mechanical strength and hardness as well as greater resistance to friction wear.
Some of the other features that the carbon industries see as a big advantage in favor of coconut carbon are:
- Coconut is a renewable source of carbon
- Coconuts grow throughout the year, with harvesting being generally 3-4 times in a year
- The coconut tree can be maintained for many years
In summary, activated carbon of coconut shell plays a very important role in the purification of drinking water, since:
- It adsorbs disinfection by-products
- Adsorption of volatile organic compounds
- Adopts pesticides and herbicides
- Removes halogens from water
- Improves the appearance of drinking water
- Improves the taste of water
