GranularWoyambitsa CarbonMitundu
Granular activated carbon (GAC) ndiwotsatsa wosunthika kwambiri womwe umagwira ntchito yofunika kwambiri pamafakitale ambiri komanso chilengedwe, chifukwa cha kapangidwe kake kodabwitsa komanso malo otambalala. Magulu ake ndi osiyanasiyana, okhala ndi mitundu yosiyanitsidwa ndi zopangira, kagawidwe ka pore, ndi zolinga zenizeni zomwe amagwira.
GAC yopangidwa ndi malashandi mtundu wodziwika bwino, wotengedwa kuchokera ku malasha a bituminous kapena lignite kudzera munjira zingapo zoyatsa. Chomwe chimasiyanitsa ndi kuuma kwake kodabwitsa, komwe kumamuthandiza kupirira kugwiriridwa molimba komanso kugwiritsidwa ntchito kwanthawi yayitali popanda kuwonongeka kwakukulu. Mapangidwe a macroporous a GAC opangidwa ndi malasha amakhala opangidwa bwino kwambiri, okhala ndi ma pores omwe amatha kugwira bwino mamolekyu akulu. Pochiza madzi, izi zimapangitsa kuti pakhale njira yothetsera mankhwala ophera tizilombo, omwe nthawi zambiri amakhala ndi zovuta komanso zazikulu za maselo, komanso zosungunulira za mafakitale zomwe zingakhalepo m'madzi oipitsidwa. Kutsika mtengo kwake ndi mwayi wina wofunikira, ndikupangitsa kuti ikhale yofunika kwambiri m'mafakitale oyeretsa madzi. Mwachitsanzo, mizinda yambiri imadalira GAC yopangidwa ndi malasha m'masefedwe awo kuti madzi omwe amaperekedwa m'mabanja azikhala opanda zowononga zowononga zachilengedwe.
GAC yopangidwa ndi matabwandi mitundu ina yomwe imagwiritsidwa ntchito kwambiri, yopangidwa kuchokera kumitengo yolimba monga oak, komanso zipolopolo za kokonati. Mwa izi, GAC yokhala ndi chipolopolo cha kokonati imayenera kutchulidwa mwapadera. Imakhala ndi mawonekedwe a microporous, pomwe tinthu ting'onoting'ono tating'onoting'ono timakwanira bwino kutsatsa mamolekyu ang'onoang'ono. Izi zikuphatikizapo klorini, yomwe nthawi zambiri imawonjezeredwa ku madzi koma imatha kukhudza kukoma ndi fungo, zinthu zowonongeka (VOCs) zomwe zimatha kutulutsidwa kuchokera kuzinthu zosiyanasiyana zamakampani, ndi zinthu zina zomwe zimayambitsa zokonda ndi fungo losasangalatsa m'madzi kapena mpweya. Chikhalidwe ichi chimapangitsa GAC yopangidwa ndi kokonati kukhala yabwino kwambiri pazosefera zamadzi okhalamo, komwe eni nyumba amafuna kukonza madzi awo akumwa. Imagwiritsidwanso ntchito kwambiri m'makina oyeretsa mpweya, zomwe zimathandiza kuchotsa tinthu tating'ono towononga mpweya m'nyumba, maofesi, ndi malo ena otsekedwa.
Pomaliza, mitundu yambiri ya granular activated carbon, iliyonse ili ndi katundu wake wapadera, imapereka njira zothetsera mavuto osiyanasiyana oyeretsa. Pogwiritsa ntchito mawonekedwe awo apadera komanso azinthu, mitundu iyi ya GAC ikupitilizabe kukhala yofunikira pakusunga madzi oyera, mpweya, ndikuwonetsetsa kuti zinthu zosiyanasiyana zili bwino m'mafakitale.
Kusankha GAC yoyenera kumatengera kugwiritsa ntchito. Coconut shell GAC ndiyabwino pazosefera zamadzi, pomwe GAC yopangidwa ndi malasha ndiyotsika mtengo pakugwiritsa ntchito mafakitale. Pamene malamulo a chilengedwe akukulirakulira, ntchito ya GAC pakuwongolera kuipitsa ipitilira kukula.
