Coconut charcoal: One of the best sources of Activated Carbon
Industrialization and high-input agriculture are continuously expanding into the developing world, and chemical impurities such as pesticides, herbicides, and fertilizers are finding their way into drinking water supplies and have been associated with severe health-related issues. Activated carbon is a water treatment technology that has the capacity to remove these problematic chemicals from water sources.
Coconut shell activated carbon filters are most preferred pre-filters in the drinking water purification industry. With activated carbon pre-filters becoming a most common element in water purifiers, coconut shell is the ideal source which primarily consist pores in micro range. Nearly 85–90% surface area of coconut shell activated carbon subsists as micro-pores. These small pores counterpart the size of pollutant molecules in drinking water and thus are very efficient in trapping them.
The dominance of micro-pores in coconut shell carbon furnishes a tight structure endowed with good mechanical strength and rigidity and also high resistance to defy grinding down or wearing away by friction. Some of other qualities which the water purification and carbon industries, see as a huge advantage in favor of coconut shell carbon are as follows:
• Coconut is a renewable source of carbon
• Coconuts grow throughout the year, with harvesting generally occurring 3–4 times in a year
• Coconut tree can be preserved for several years
To summarize, carbon-related key points are as follows:
• Adsorbs disinfectant by-products
• Adsorbs pesticide and herbicide
• Removes halogens from water
• Improves appearance of drinking water
• Improves taste of water
• Adsorbs odor
• Adsorbs and removes sulfide in flue gas, mercury vapor etc.
It can be used for water treatment, water purification water treatment, the height of ultrapure water production, water purifier, water treatment, industrial water. Coconut shell based carbon filters which fall into the category of Granular Activated Carbons (GAC), can effectively soak up chemicals like chloramines which cannot be effectively removed by regular granular activated carbon.
The source and quality of the carbon play a major role in the quality and consistency of activated carbon produced, and coconut shells as a key source help reduce ecological impact, being a local agricultural waste byproduct, is optimal to be used as a replacement in the activated carbon production process. It is also the most simple, inexpensive, and effective activated carbon product ideal for water purification.
