oal based activated carbon e atiina ae e ala i se faasologa o faiga e pei o le carbonization, faamalūlūina, faagaioiina, ma le fufuluina. O lona foliga mai e masani ona uliuli cylindrical activated carbon, amorphous coal particle activated carbon, lea e lauiloa foi o le carbon nutimomoia. Cylindrical activated carbon, lea e taʻua foi o le columnar carbon, e masani lava ona faia mai i le pauta mea mata ma fusi, lea e fefiloi, extruded, ona carbonized, activated, ma isi faiga. E mafai fo'i ona fa'aoso i le fa'aaogaina o le pauta fa'agaoioi carbon ma fa'amau. Ua atiina ae le fausaga pore, lelei adsorption faatinoga, maualuga malosi masini, faigofie e toe faʻafouina, ma tau maualalo; Faʻaaogaina mo le faʻamamaina o kasa oona, faʻamaʻi otaota otaota, fale gaosi oloa ma vai faʻamama togafitiga, toe faʻaleleia le solvent, ma isi vaega.
