I-Granular activated carbon yenziwa ikakhulu kwiqokobhe lekhokhonathi, iqokobhe leziqhamo, kunye namalahle ngothotho lweenkqubo zemveliso.Ikwahlulwa ibe ngamasuntswana asisigxina kunye ne-amorphous.Iimveliso zisetyenziswa kakhulu kumanzi okusela, kumanzi amashishini, ukusela, ukunyangwa kwerhasi yenkunkuma, i-decolorization, i-desiccants, ukucocwa kwegesi, kunye nezinye iinkalo.
Ukubonakala kwe-granular activated carbon ngamasuntswana amnyama amorphous;Iphuhlise ubume be-pore, ukusebenza kakuhle kwe-adsorption, amandla aphezulu omatshini, kwaye kulula ukuyihlaziya ngokuphindaphindiweyo;Isetyenziselwa ukucocwa kweegesi ezinetyhefu, ukucocwa kwegesi yenkunkuma, ukucocwa kwamanzi kwimizi-mveliso nasekhaya, ukubuyiswa kwe-solvent, kunye neminye imiba.
