Mafirita ekabhoni anoshandiswa dzimwe nguva anonzi mafirita emarasha ane zvidimbu zvidiki zvekabhoni, zvakaita segranular kana block, izvo zvakaonekwa kuti zvine maburi akawanda.Magiramu mana chete e-activated carbon ane nzvimbo yakaenzana nenhandare yenhabvu.(6400 sqm). Ndiyo nzvimbo yakakura kwazvo inoita kuti mafirita ekabhoni anoshanda ashande zvakanaka mukukweva (kunyanya kubvisa) tsvina nezvimwe zvinhu.
Kana mvura ikayerera nemumafirita ecarbon anoshandiswa, makemikari anonamira kune kabhoni zvichikonzera kubuda kwemvura yakachena.Kushanda zvakanaka kunoenderana nekuyerera kwemvura uye tembiricha yayo. Saka mafirita madiki ecarbon active anofanira kushandiswa nemvura inotonhora uye ine simba shoma.
Pamusoro penzvimbo yepamusoro, mafirita ekabhoni anoshanda anogona kunge aine kugona kwakasiyana maererano nehukuru hwezvinhu zvinosvibisa zvavanobvisa. Chimwe chikonzero ndechekuti kabhoni inoshanda zvakanaka uye makoko ekokonati akaonekwa kuti anoshanda zvakanaka. Kabhoni inoshanda inogonawo kugadzirwa nematanda kana marasha uye inotengeswa semabhuroko ekabhoni inoshanda kana kuti carbon blocks.
Chimwe chinhu ndechekuti saizi yezvimedu zvinobvumidzwa nefirita sezvo izvi zvichipa dziviriro yechipiri. Granular activated carbon (GAC) haina muganho chaiwo sezvo zvinhu zvacho zvine maburi. Activated carbon muchimiro che carbon blocks kune rumwe rutivi inowanzova nehukuru hwemaburi huri pakati pe 0.5 kusvika 10 micron. Dambudziko nehukuru hudiki nderekuti kuyerera kwemvura kunopedzisira kwadzikira sezvo kunyange zvimedu zvemvura zvichinetseka kupinda. Saka maburi e carbon akajairika ari pakati pe 1-5 micron.
Kabhoni inoshandiswa inogona kushanda zvakanaka mukuderedza mazana ezvinhu zvinosanganisira zvinosvibisa nemamwe makemikari anobva mumvura yepombiZvisinei, zvidzidzo zvinonyanya kutaurwa nezvazvo neEPAuyeNSFtaura kuti zvinobudirira kubvisa makemikari ari pakati pe60-80, zvinobudirira kuderedza mamwe makumi matatu uye zvine mwero kuderedza kwemakumi maviri nemaviri.
Kubviswa kwemvura zvakanaka kwakakosha uye zvinoenderana nemhando yekabhoni inoshandiswa uye kuti yakashandiswa sei (GAC vs carbon block). Iva nechokwadi chekusarudza sefa inobvisa tsvina inokonzeresa dambudziko remvura yemupombi yemuno.
