I-GranularIkhabhoni ecushiweIzinhlobo
I-Granular activated carbon (GAC) iyi-adsorbent eguquguquka kakhulu edlala indima ebalulekile ekusebenzeni kwezimboni eziningi kanye nemvelo, ngenxa yesakhiwo sayo esiyinkimbinkimbi kanye nendawo ebanzi. Ukuhlukaniswa kwayo kuhlukene, kunezinhlobo ezihlukaniswa ngezinto ezingavuthiwe, ukusatshalaliswa kosayizi wezimbotshana, kanye nezinjongo ezithile ezisebenzayo.
I-GAC esekwe emalahleniiwuhlobo oluvelele, olutholakala kumalahle e-bituminous noma e-lignite ngochungechunge lwezinqubo zokuvula. Okuyihlukanisayo ubulukhuni bayo obumangalisayo, obuyenza ikwazi ukumelana nokuphathwa kanzima kanye nokusetshenziswa isikhathi eside ngaphandle kokuwohloka okukhulu. Isakhiwo esikhulu se-GAC esekwe emalahleni sithuthukiswe kahle, sinezimbotshana ezingabamba ngempumelelo ama-molecule amakhulu ezinto eziphilayo. Ekwelashweni kwamanzi, lokhu kwenza kube inketho yokuqeda izibulala-zinambuzane, ezivame ukuba nezinhlaka eziyinkimbinkimbi nezinkulu zamangqamuzana, kanye nezincibilikisi zezimboni ezingase zibe khona emanzini angcolile. Ukonga kwayo kwezindleko kungenye inzuzo ebalulekile, okuyenza ibe yisisekelo sezitshalo zikamasipala zokuhlanza amanzi. Isibonelo, amadolobha amaningi athembele ku-GAC esekelwe emalahleni ezinhlelweni zawo zokuhlunga ukuze aqinisekise ukuthi amanzi ahlinzekwa ezindlini awanawo ukungcola okukhulu kwemvelo okuyingozi.
I-GAC esekwe ngokhunikungenye izinhlobonhlobo ezisetshenziswa kabanzi, ezenziwe ngokhuni oluqinile njenge-oki, kanye namagobolondo kakhukhunathi. Phakathi kwalokhu, i-GAC esekwe kugobolondo likakhukhunathi ifanelwe ukukhulunywa ngokukhethekile. Inesakhiwo esine-microporous ikakhulukazi, lapho izimbotshana ezincane zifaneleka ngokuphelele ukukhangisa ama-molecule amancane. Lokhu kuhlanganisa i-chlorine, evamise ukungezwa emanzini kodwa ingathinta ukunambitheka nephunga, izakhi eziphilayo ezishintshashintshayo (VOCs) ezingase zikhishwe ezinqubweni ezihlukahlukene zezimboni, nezinye izinto ezibangela ukunambitheka okungajabulisi kanye nephunga emanzini noma emoyeni. Lesi sici senza i-GAC esekwe kwigobolondo likakhukhunathi ibe yinketho ephezulu yezihlungi zamanzi zokuhlala, lapho abanikazi bezindlu befuna ukuthuthukisa ikhwalithi yamanzi abo okuphuza. Iphinde ithole ukusetshenziswa okubanzi ezinhlelweni zokuhlanza umoya, isiza ekususeni ama-molecule amancane ayingozi emoyeni ezindlini, emahhovisi nakwezinye izindawo ezivalekile.
Sengiphetha, uhla olubanzi lwezinhlobo zekhabhoni ecushiwe, ngayinye enesethi yayo ehlukile, ihlinzeka ngezixazululo ezihambisanayo zenqwaba yezinselelo zokuhlanza. Ngokusebenzisa izici zabo ezihlukile zesakhiwo nezinto ezibonakalayo, lezi zinhlobo ze-GAC ziyaqhubeka nokuba semqoka ekugcineni amanzi ahlanzekile, umoya, kanye nokuqinisekisa ikhwalithi yemikhiqizo ehlukahlukene kuzo zonke izimboni.
Ukukhetha i-GAC efanele kuncike kuhlelo lokusebenza. Igobolondo likakhukhunathi i-GAC lilungele izihlungi zamanzi, kuyilapho i-GAC esekelwe emalahleni ibiza ukusetshenziswa kwezimboni. Njengoba imithetho yezemvelo iqina, indima ye-GAC ekulawuleni ukungcola izolokhu ikhula.
