Reminder of what exactly activated charcoal or activated carbon: the active charcoal or activated carbon is the high-temperature char becomes micro-porous. These are the carbon atoms which gives it a strong absorbency due to its high surface micro caves interconnected scientific name van der Waals force. Details of the activated carbon: it has the property of trapping organic particles and some chemical molecules when fluids through it. A little history on activated carbon: evidence for the use of activated carbon by the Egyptians to filter water date back to 1500 years BC or medicinal use by Hippocrates in ancient times. This is the twentieth century that the exploitation of charcoal has developed and diversified for its multiple applications in filtration, discoloration, medical, chemistry, etc. Since then, several manufacturing processes have been developed, including chemistry (Bayer) and steam (Ostreijko) to increase production efficiency and versatile.
