Ukuguquguquka kwekhabhoni esebenzayo akupheli, kwaye kusetyenziswa iindlela ezingaphezu kwe-1,000 ezaziwayo. Ukusuka ekumbiweni kwegolide ukuya ekucoceni amanzi, ukuveliswa kwezinto zokutya nokunye, ikhabhoni esebenzayo inokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezahlukeneyo.
Iikhabhoni ezisebenzayo zenziwe ngezinto ezahlukeneyo zemithombo yekhabhoni – kuquka amaqokobhe ekhokhonathi, ipeat, umthi oqinileyo nothambileyo, amalahle e-lignite kunye ne-olive pit ukukhankanya nje ezimbalwa. Nangona kunjalo, naziphi na izinto eziphilayo ezinomxholo ophezulu wekhabhoni zingasetyenziswa ngokufanelekileyo ukwenza iikhabhoni ezisebenzayo ngokuguqulwa kwendalo kunye nokubola kobushushu.
Eyona ndlela ixhaphakileyo yokusebenzisa ikhabhoni esebenzayo kwihlabathi lanamhlanje igxile ekunyangweni kwamanzi amdaka enkqubo, amanzi amdaka emizi-mveliso namashishini kunye nemiba yokunciphisa ivumba lomoya/ivumba. Xa iguqulwa ibe ziikhabhoni ezisebenzayo, izixhobo zomthombo wekhabhoni zinamandla okucoca nokususa uluhlu olubanzi lwezinto ezingcolisayo emanzini nakwimijelo yamanzi amdaka.
Indima ebalulekileyo ye-activated carbon ekunyangweni kwamanzi (enye yeekhemikhali zonyango lwamanzi)
Iikhabhoni ezisebenzayo zibonelela ngenye yezona ndlela zisebenzayo zokususa izinto ezingcolisayo ezibalulekileyo ezifana ne-THM kunye ne-DBP kunye nokususa izinto eziphilayo kunye nezibulali-ntsholongwane ezisele emanzini. Oku akuphuculi nje kuphela incasa kwaye kunciphisa iingozi zempilo kodwa kukhusela nezinye iiyunithi zonyango lwamanzi ezifana nee-reverse osmosis membranes kunye nee-ion exchange resins kumonakalo onokwenzeka ngenxa ye-oxidation okanye i-organic fouling.
I-activated carbon isaqhubeka nokuba yenye yezona ndlela zonyango lwamanzi zithandwayo kulo lonke elase-UK nase-Ireland ngenxa yeendlela zayo ezahlukeneyo zokusebenza kunye nemisebenzi.
Iintlobo zeekhabhoni ezisebenzayo
Ikhabhoni esebenzayo idla ngokusetyenziswa ukunyanga amanzi enkqubo kwiinkqubo ezimbini ezahlukeneyo kakhulu - iikhabhoni ezisebenzayo ezicoliweyo (i-PAC) kunye neekhabhoni ezisebenzayo ezi-granular (i-GAC). Nangona kunjalo, iindlela zomthamo kunye namatyala okusetyenziswa kolu hlobo ngalunye lweekhabhoni ezisebenzayo zahlukile kakhulu. Ukukhethwa kohlobo oluthile lweekhabhoni ezisebenzayo zokunyanga amanzi kuya kuxhomekeka kuhlobo lokusetyenziswa okuthile, isiphumo esifunekayo kunye nayo nayiphi na imida yenkqubo ekhoyo.
Iikhabhoni ezisebenza ngomgubo zisetyenziswa zizityalo zonyango lwamanzi ukulawula incasa nevumba kunye nokuqinisekisa ukususwa kweekhemikhali eziphilayo. Ii-PAC zongezwa kwangethuba kwinkqubo yonyango ukuze kubekho ixesha lokudibana kuphela ngaphambi kokuba kongezwe ezinye iikhemikhali zonyango kumjelo wamanzi.
Akufanele zigqunywe ngezinye iikhemikhali zonyango lwamanzi ngaphambi kokuba zinikwe ixesha elaneleyo lokudibana nomsinga wamanzi (ngesiqhelo ii-PAC ziya kufuna ubuncinane imizuzu eli-15 yokudibana zodwa nomsinga wamanzi). Okubaluleke kakhulu, ii-PAC akufuneki zongezwe ngaxeshanye ne-chlorine okanye i-potassium permanganate njengoko iikhemikhali zonyango lwamanzi ezinjalo ziya kufunxwa yi-activated carbon powder.
Iidosi eziqhelekileyo ezifunekayo zingaba phakathi kwe-1 ukuya kwi-100 mg/L kuxhomekeke kuhlobo kunye nenqanaba lokungcola, kodwa iidosi ze-1 ukuya kwi-20 mg/L ziqheleke kakhulu xa kunyangwa imijelo yamanzi ngenjongo yokulawula incasa kunye nevumba. Iidosi eziphezulu ziya kufuneka apho ii-PAC zongezwa kamva kwinkqubo yonyango, ukuvumela nayiphi na into yokufunxwa kwezinye iikhemikhali zonyango ezongezwe kwangoko kwinkqubo. Ii-PAC kamva zisuswa kwimijelo yamanzi ngenkqubo yokuthuthwa okanye ngeebhedi zokucoca.
