Izihlungi zekhabhoni ezicushiwe ngezinye izikhathi ezibizwa ngokuthi izihlungi zamalahle ziqukethe izingcezu ezincane zekhabhoni, eziyimbudumbudu noma ngesimo sebhulokhi, ezithathwe njengezinezimbotshana ezimbotshana kakhulu.Amagremu angu-4 kuphela ekhabhoni ecushiwe anendawo elingana nenkundla yebhola(6400 sqm).Indawo engaphezulu enkulu evumela izihlungi zekhabhoni ezisebenzayo ukuthi zisebenze kahle ekukhangiseni (ekususeni empeleni) ukungcola nezinye izinto.
Lapho amanzi egeleza ngezihlungi zekhabhoni ezisebenzayo amakhemikhali anamathela kukhabhoni okuholela ekuphumeni kwamanzi ahlanzekile.Ukusebenza kahle kuncike ekugelezeni nasekushiseni kwamanzi.Ngakho-ke izihlungi eziningi zekhabhoni ezisebenzayo kufanele zisetshenziswe ngomfutho ophansi kanye namanzi abandayo.
Ngaphezu kwendawo yezihlungi zekhabhoni ezisebenzayo zingase zibe namandla ahlukene ngokobukhulu bezingcolisi ezizisusayo.Esinye isici izinga lekhabhoni ecushiwe enamagobolondo kakhukhunathi afakazelwe ukuthi asebenza kahle kakhulu.Ikhabhoni ecushiwe ingenziwa futhi ngokhuni noma ngamalahle futhi ithengiswe njenge-granular activated carbon noma i-carbon blocks.
Esinye isici ubukhulu bezinhlayiya isihlungi esizovumela ukuthi sidlule njengoba lokhu kunikeza ukuzivikela kwesibili.I-Granular activated carbon (GAC) ayinawo umkhawulo othize njengoba impahla iyizimbotshana.Ikhabhoni ecushiwe ngendlela yamabhlogo ekhabhoni ngakolunye uhlangothi ivamise ukuba nosayizi wembotshana ophakathi kuka-0.5 kuya ku-10 micron.Inkinga ngosayizi abancane ukuthi ukugeleza kwamanzi kugcina kuncishisiwe njengoba ngisho nezinhlayiya zamanzi zidonsa kanzima ukuze zidlule.Ngakho-ke amabhlogo ekhabhoni ajwayelekile aphakathi kwe-1-5 micron.
Ikhabhoni ecushiwe ingasebenza kahle kuukunciphisa amakhulukhulu ezinto ezihlanganisa ukungcola namanye amakhemikhali aphuma emanzini ompompi.Nokho, izifundo ezicashunwe kakhulu nguEPAfuthiI-NSFfuna ukususwa okusebenzayo kwamakhemikhali aphakathi kuka-60-80, ukuncishiswa okusebenzayo kwamanye angama-30 kanye nokwehliswa okuphakathi kwama-22.
Ibanga lokususwa okusebenzayo libalulekile futhi lincike kwikhwalithi yekhabhoni ecushiwe esetshenzisiwe nokuthi ingaluphi uhlobo (i-GAC vs carbon block).Qiniseka ukuthi ukhetha isihlungi esisusa ukungcola okukhathazayo kwamanzi ompompi wasendaweni yangakini.
