Ngo-2020, i-Asia Pacific yabamba isabelo esikhulu kunazo zonke emakethe ye-carbon activated global.I-China ne-India zingabakhiqizi ababili abahamba phambili bekhabhoni ecushiwe emhlabeni jikelele.E-India, imboni yokukhiqiza ikhabhoni ecushiwe ingenye yezimboni ezikhula ngokushesha.Ukukhula kwezimboni kulesi sifunda kanye nokwenyuka kwemizamo kahulumeni yokwelapha imfucuza yezimboni kubhebhethekise ukusetshenziswa kwekhabhoni ecushiwe.Ukwanda kwenani labantu kanye nesidingo esikhulu sokukhiqizwa kwezimboni nezolimo kunesibopho sokukhulula imfucuza emithonjeni yamanzi.Ngenxa yokwanda kwesidingo samanzi ezimbonini ezihlobene nokuphehlwa kukadoti ngenani elikhulu, imboni yokuhlanza amanzi ithola ukusetshenziswa kwayo e-Asia Pacific.Ikhabhoni ecushiwe isetshenziswa kakhulu ukuhlanzwa kwamanzi.Lokhu kulindeleke ukuthi kube nomthelela ekukhuleni kwemakethe esifundeni.
Ukukhishwa kwe-Mercury kukhishwa ezitshalweni zamandla asetshenziswa ngamalahle futhi kuyingozi emvelweni nempilo yabantu.Amazwe amaningi abeke imithetho enanini lobuthi obukhishwa kulezi zikhungo zikagesi.Amazwe asathuthukayo awakazisunguli izinhlaka zokulawula noma zomthetho nge-mercury;nokho-ke, ukuphathwa kwe-mercury kuklanyelwe ukuvimbela ukungcola okuyingozi.I-China ithathe izinyathelo zokuvimbela nokunciphisa ukungcoliswa kwe-mercury ngokusebenzisa imihlahlandlela eminingi, imithetho, nezinye izilinganiso.Ubuchwepheshe bokulawula okuthuthukile, okuhlanganisa ihadiwe nesofthiwe, kusetshenziswa ukunciphisa ukukhishwa kwe-mercury.Ikhabhoni ecushiwe ingenye yezinto ezigqame kakhulu ezisetshenziswa kuhardware yalobu buchwepheshe ukuhlunga umoya.Imithethonqubo yokulawula ukukhishwa kwe-mercury ukuvimbela izifo ezibangelwa ubuthi be-mercury iye yanda emazweni amaningi.Ngokwesibonelo, iJapane yamukela imithetho eqinile mayelana nokukhishwa kwe-mercury ngenxa yesifo saseMinamata esasibangelwa ubuthi obukhulu be-mercury.Ubuchwepheshe obusha, obufana ne-Activated Carbon Injection, busetshenziswa ukuze kubhekwane nokukhishwa kwe-mercury kulawa mazwe.Ngakho-ke, imithethonqubo ekhulayo yokukhishwa kwe-mercury emhlabeni wonke iqhuba isidingo sekhabhoni ecushiwe.
Ngohlobo, imakethe yekhabhoni ecushiwe ihlukaniswe yaba yimpuphu, i-granular, ne-pelletized & nabanye.Ngo-2020, ingxenye yempushana yabamba isabelo semakethe esikhulu kunazo zonke.Ikhabhoni ecushiwe esekwe uyimpushana yaziwa ngokusebenza kahle kwayo nezici, njengosayizi wezinhlayiyana ezinhle, okwandisa indawo engaphezulu ye-adsorption.Usayizi wekhabhoni ecushiwe uyimpuphu usebangeni elingu-5‒150Å.Ikhabhoni ecushiwe esuselwa kumpushana inezindleko eziphansi kakhulu.Ukusetshenziswa okwandayo kwekhabhoni eyenziwe ngempushana kuzoqhubeka nokukhulisa isidingo ngesikhathi sokubikezela.
Ngokusekelwe kuhlelo lokusebenza, imakethe yekhabhoni ecushiwe ihlukaniswe yaba ukwelashwa kwamanzi, ukudla neziphuzo, imithi, izimoto, nokunye.Ngo-2020, ingxenye yokuhlanza amanzi yabamba isabelo semakethe esikhulu kunazo zonke ngenxa yokwanda kwezimboni emhlabeni wonke.Ikhabhoni ecushiwe iqhubekile nokusetshenziswa njengendawo yokuhlunga amanzi.Amanzi asetshenziswa ekukhiqizeni angcoliswa futhi adinga ukwelashwa ngaphambi kokuwakhiphela emanzini.Amazwe amaningi anemithetho eqinile mayelana nokwelashwa kwamanzi kanye nokukhishwa kwamanzi angcolile.Ngenxa yomthamo ophezulu we-adsorption wekhabhoni ecushiwe obangelwa ukuqina kwayo nendawo enkulu, isetshenziswa kabanzi ukususa ukungcola emanzini.
Amazwe amaningi ancike ekuthengisweni kwalezi zinto zokusetshenziswa ukulungisa ikhabhoni ecushiwe abhekane nezinselelo ezinkulu zokuthola leyo nto.Lokhu kuholele ekuvaleni kancane noma okuphelele kweziza zokukhiqiza ikhabhoni ecushiwe.Kodwa-ke, njengoba ezomnotho zihlela ukuvuselela ukusebenza kwazo, isidingo sekhabhoni ecushiwe kulindeleke ukuthi sikhuphuke emhlabeni jikelele.Isidingo esikhulayo sekhabhoni ecushiwe kanye nokutshalwa kwezimali okubalulekile kwabakhiqizi abavelele ukukhulisa umthamo wokukhiqiza kulindeleke ukuthi kuqhubekisele phambili ukukhula kwekhabhoni ecushiwe ngesikhathi sokubikezela.
