Activated carbon is widely recognized for its exceptional adsorption properties in water purification, thanks to its remarkable porosity and expansive surface area. While various natural substances are used to produce activated carbon, including lignite, bituminous and anthracite coal, peat, and wood, it is the coconut shell that holds a special place in this domain.
Coconut-shell based activated carbon stands out as predominantly microporous, boasting the least dustiness among its counterparts. This unique characteristic makes it highly efficient in adsorbing organic chemicals, making it an ideal choice for water purification. In fact, compared to other types of activated carbon, filters made from coconut-shell based activated carbon exhibit the highest hardness, further enhancing their effectiveness in water treatment.
The coconut shell charcoal offers an increased surface area and a denser network of micro-pores, surpassing the porosity of many popular activated carbons. In fact, it boasts 50% more micro-pores than coal-based activated carbon. This exceptional porosity equips coconut-shell based activated carbon with superior adsorption capabilities, attracting a wide range of contaminants, from small to large. Its ability to adsorb a vast amount and variety of contaminants, including organic chemicals and gases, contributes to its reputation as a highly effective water purification method.
Unlike some other forms of charcoal, coconut shell activated carbon does not leave an ashy taste in the water. Its friendliness, effectiveness, and non-leaching properties make it an optimal choice for obtaining high-quality purified water. Furthermore, manufacturing activated carbon from coconut shells is easier and less time-consuming. With a readily available supply of coconut shells year-round, this process does not negatively impact the environment, as no trees need to be cut down for its production. Abundant availability of the raw material ensures a sustainable source for coconut activated carbon.
While coconut activated carbon blocks used in water filtration may be slightly more expensive than those derived from coal or wood, they offer significantly superior efficiency, making them an excellent option for high-quality domestic water filtration.
Understanding the Distinction: Carbon vs. Activated Carbon
It is important to distinguish between regular carbon and activated carbon, primarily in terms of their surface area to volume ratio. Activated carbon surpasses regular carbon in this aspect, possessing a significantly higher surface area to volume ratio. This disparity translates into superior adsorption capabilities. To put it into perspective, just 4 grams of activated carbon exhibits a surface area equivalent to a football field, spanning 6400 square meters.
In conclusion, the coconut shell emerges as a true powerhouse when it comes to water purification. Its coconut-shell based activated carbon demonstrates exceptional microporosity, efficient adsorption of organic chemicals, and unparalleled water purity. Harnessing the inherent benefits of coconut shell activated carbon allows us to enjoy the finest quality of purified water while embracing sustainability and environmental consciousness.
