How Is Made?
Making coconut-shell activated carbon is a three-step process that starts with charring. The first step is to char the coconut shells by subjecting them to high temperatures, typically between 500-600 degrees Celsius, for many hours.
The optimal temperature for charring is between 932-1,112 degrees Fahrenheit. This process can be done in a drum kiln with a chimney, which helps create higher interior temperatures by limiting oxygen flow.
After several hours, usually around 12 hours, the coconut shells will become charcoal. The coconut shells at the bottom of the drum kiln will typically carbonize first due to the limited oxygen flow.
The coconut shells need to be cleaned and dried before charring, with the exterior fibers removed. This preparation step is crucial for the charring process to occur effectively.
Time to work
A carbon block can perform a more significant range of filtration tasks compared to other filtration technologies.
It features a sintered porous structure or filtration housing made for carbon, acting as the filtration media with various additives, and thermoplastic binders.
This filtration system will work immediately once equipped.
