Yintoni esetyenziselwa iFerric Chloride ekunyangweni kwamanzi?

I-Ferric Chlorideyikhemikhali enefomyula iFeCl3. Isetyenziswa kakhulu kwiinkqubo zokunyanga amanzi njenge-coagulant ngenxa yokusebenza kwayo ekususeni ukungcola kunye nokungcola emanzini kwaye ngokubanzi isebenza ngcono emanzini abandayo kune-alum. Malunga ne-93% ye-ferric chloride isetyenziswa ekucoceni amanzi, oko kukuthi amanzi amdaka, amanzi amdaka, amanzi okupheka kunye namanzi okusela. I-ferric chloride isetyenziswa kakhulu kwimo eqinileyo njengesisombululo sokunyanga amanzi kunye namanzi amdaka.

Ukusetyenziswa kwe-ferric chloride kunyango lwamanzi:

1. Ukuxinana kunye nokuQokelela: Enye yezona ndlela ziphambili zokusebenzisa i-ferric chloride ekucoceni amanzi kukwenza i-coagulant. Xa yongezwa emanzini, i-ferric chloride idibana namanzi ukuze ivelise i-ferric hydroxide kwaye le yokugqibela ifunxa amasuntswana axhonyiweyo, izinto eziphilayo, kunye nezinye izinto ezingcolileyo ukuze zenze amasuntswana amakhulu, anzima abizwa ngokuba yi-flocs. Ezi flocs zinokuhlala ngokulula ngexesha leenkqubo zokunyibilikisa okanye zokucoca, okuvumela ukususwa kokungcola emanzini.

2. Ukususwa kweFosforasi: I-Ferric chloride isebenza kakhulu ekususeni i-phosphorus emanzini. I-Phosphorus sisondlo esiqhelekileyo esifumaneka emanzini amdaka, kwaye amanqanaba aphezulu anokubangela i-eutrophication kwiindawo zamanzi ezifumanekayo. I-Ferric chloride yenza ii-complexes ezinganyibilikiyo kunye ne-phosphorus, enokususwa ngokuna okanye ngokuhluzwa, inceda ekunciphiseni amanqanaba e-phosphorus emanzini.

3. Ukususwa kweNsimbi Enzima: I-Ferric chloride ikwasetyenziselwa ukususa iintsimbi ezinzima, ezifana ne-arsenic, i-lead, kunye ne-mercury, emanzini. Ezi zintsimbi zinokuba yingozi kakhulu kwaye zibe yingozi enkulu kwimpilo ukuba zikhona emanzini okusela. I-Ferric chloride yenza ii-hydroxide zesinyithi ezinganyibilikiyo okanye ii-oxychlorides zesinyithi, ezinokususwa ngenkqubo yokuna kwemvula okanye yokuhluza, nto leyo enciphisa ngempumelelo ukuxinana kweentsimbi ezinzima emanzini.

4. Ukususwa kombala nevumba: I-Ferric chloride iyasebenza ekususeni imibala kunye neekhompawundi ezibangela ivumba emanzini. I-oxidize iikhompawundi ze-organic ezibangela umbala kunye nevumba, iziqhekeza zibe zizinto ezincinci, ezingabalulekanga kangako. Le nkqubo inceda ekuphuculeni umgangatho wobuhle bamanzi, iwenze afaneleke ngakumbi kwiinjongo zokusela, zoshishino, okanye zokuzonwabisa.

5. Uhlengahlengiso lwe-pH: Ngokulawula i-pH, i-ferric chloride inokwenza ngcono ukusebenza kwezinye iinkqubo zonyango, ezinje ngokujiya, ukuqunjelwa, kunye nokubulala iintsholongwane. Uluhlu lwe-pH olufanelekileyo lunokunceda ekudaleni iimeko ezifanelekileyo zokususa ukungcola kunye nokungcola emanzini.

6. Ulawulo lweMveliso yoKubulala iintsholongwane: I-ferric chloride inokunceda ukulawula ukwakheka kweemveliso zokubulala iintsholongwane (ii-DBP) ngexesha lokunyanga amanzi. Xa isetyenziswa kunye nezibulali-ntsholongwane ezifana ne-chlorine, i-ferric chloride inokunciphisa ukwakheka kwee-DBP ezifana nee-trihalomethanes (ii-THM) kunye nee-haloacetic acids (ii-HAA), ezinokubangela umhlaza. Oku kuphucula ukhuseleko kunye nomgangatho wamanzi okusela.

7. Ukucocwa kweSludge: I-ferric chloride ikwasetyenziswa kwiinkqubo zokucocwa kweSludge kwizityalo zokunyanga amanzi amdaka. Inceda ekulungiseni iSludge ngokukhuthaza ukwakheka kwe-flocs ezinkulu nezixineneyo, ezihlala ngokukhawuleza kwaye zikhuphe amanzi ngokufanelekileyo. Oku kuphumela ekusebenzeni ngcono kokucocwa kweSludge kunye nokunciphisa umthamo weSludge, okwenza kube lula kwaye kungabizi kakhulu ukuphatha nokulahla iSludge.

I-Ferric Chloride idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zokunyanga amanzi, kubandakanya ukujiya, ukususwa kwe-phosphorus kunye ne-heavy metal, ukususwa kombala nevumba, ukulungiswa kwe-pH, ulawulo lokubulala iintsholongwane kwimveliso, kunye nokususwa kodaka. Ukuguquguquka kwayo nokusebenza kwayo kuyenza ibe yikhemikhali exabisekileyo ekunyangweni kwamanzi okusela kunye namanzi amdaka, inceda ukuqinisekisa ukhuseleko, umgangatho, kunye nokuzinza kwemithombo yamanzi.
