In water treatment applications, all three types of carbon (coconut, coal and wood) are used, depending on the nature of the treated drinking water and wastewater. Therefore, it is necessary to compare various types of carbon according to their specifications.


Porosity plays an important role in choosing the right carbon type. Coconut activated carbon contains many micropores, while coal activated carbon mainly contains mesopores and micropores, while wood activated carbon only contains mesopores and macropores. coal based carbon pellets If the molecular size of the impurity is less than 100 Angstroms, coconut carbon can be preferred. Similarly, if the molecular size of the impurity is between 100 and 1000 angstroms, we can use coal. If the molecular size of the impurity is greater than 1000 angstroms, wood carbon can be considered.


1. Wood activated carbon is most suitable for decolorization in the form of powder.


2. Coal activated carbon is suitable for odor removal.


3. Coconut activated carbon is suitable for dechlorination.


Cost wise coconut activated carbon is a little more expensive than coal and wood activated carbon. "If a given volume of container is to be filled, more weight of coconut activated carbon will be required due to its high density.". But at the same time, due to the high hardness of coconut activated carbon, the material loss in the backwashing process is very small, which can be ignored. Therefore, the operation cost is low.


Coconut activated carbon has high wettability and low ash content. Because it is a renewable resource. carbon pellets supplier It is preferred for drinking water treatment and reverse osmosis water application. Having said that, coconut activated carbon is most suitable for drinking water products.


Coal activated carbon is used in drinking water projects. In addition, there are few other industrial applications, such as wastewater treatment and wastewater treatment. This type of carbon is most suitable for odor removal and cost-effective applications.


Choosing the right form of activated carbon depends on your application and operating costs. Professional guidance is the best way to ensure that the right product is delivered for a specific application.
