Coconut Activated Carbon finds common application in water purifiers. The large internal surface area makes it a good adsorbent for contaminants in drinking water. They have predominant pores in micro pore range. About 85-90% surface area of this activated carbon exist as micro pores. The size of these pores is ideal to trap water contaminants and hence find wide application in purification process.
The predominance of these pores gives it rigidity and mechanical strength to resist attrition and wearing away by friction. Few more features that make coconut activated carbon an ideal option in the industry are:
• Coconut is a renewable resource of carbon that grows throughout the year.
Charcoal has desirable characteristics as a fuel. It is non-smoky when burned and is not subject to organic decay, and is a concentrated form of energy; thus, while coconut shell has a heating value of 5,535 kcal/kg. And since it is a permanent crop, once planted there is no need to prepare the land with consequent expenditure of energy. It is non-seasonal and provides a continuous supply of nuts practically month after month.
• Coconut trees can be preserved for many years.
Since coconuts have a great Shelf life they can withstand any climatic condition while preservation. They in turn can be used for various purposes as well.
• Coconut activated carbon improves the taste and appearance of drinking water.
Coconut water has great benefits and the technologies developed for upgrading and bottling of matured coconut water as a soft drink using certain preservatives. Matured coconut water is being utilized successfully for production of vinegar using the technology
• It removes halogens from water.
Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate.
