Unknown to most of us, activated carbon plays a large role in our lives today. Humans drink water purified with it, breathe the air that has been scrubbed clean with it, eat food purified from it, wear clothes made with the help of it, go to war with it and heal ourselves with it.
Used extensively in various industrial, scientific and military purposes including refining & bleaching of oils and chemical solutions, in water purification, in recovery of solvents & other vapours, in recovery of gold & other precious metals and as a main ingredient in gas masks & filters that screen out toxic or biochemical gases, activated charcoal is one of the most widely used ingredient in world today.
With nearly 85-90% of its micro pores smaller than 4 nm, coconut shell activated carbon is adept at trapping contaminant molecules including tri-halo methane, pesticides, herbicides and volatile organic compounds in drinking water and other solutions and substance.
The predominance of micro-pores in coconut shell carbon also gives them a tight structure and high mechanical strength making them highly resistant to tear and wear through friction and makes coconut shell activated carbon, the most suitable filters for rough industrial and chemical purposes.
During large and small scale water purification processes, coconut shell activated carbon also removes halogens and impurities from water improving its quality, appearance and taste.
Meanwhile, a finer grade of coconut shell activated carbon known as food grade charcoal is used in a variety of medical purposes including direct digestion to remove poisonous and contaminated substance from the human digestive system and are also used in blood purification systems and liver and kidney dialysis units.
Available in various sizes and shapes, activated carbon is mostly divided into three categories based on their physical characteristics and are widely produced by Sri Lankan coconut shell activated carbon manufacturers.
Sri Lanka has also pioneered the process of green charcoal manufacturing or green charcoaling in Asia, successfully developing and introducing a pollution free method of generating electricity with the pollutant gas and heat produced in the process of manufacturing coconut shell activated charcoal.
Sri Lankan coconut shell activated carbon manufacturers have also developed distinct activated charcoal based purification solutions and application suitable for water, air, food and beverage, energy, gold and speciality series, such as activated carbon manufactured for poison absorption, dialysis, solvent and as ingredients in therapeutic and additives.
Other than helping the sustenance of humans, activated charcoal helps us move mountains, make the night sky sparkle, help us explore the depths of oceans and furthest of the universe and clean up the mistakes we make in the name of advancement of science and technology; still, it is one of the least celebrated ingredients in the world.
