I-Ferric Chloride isetshenziselwani ekuhlanzweni kwamanzi?

I-Ferric Chlorideiyinhlanganisela yamakhemikhali enefomula i-FeCl3. Isetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi njenge-coagulant ngenxa yokusebenza kwayo kahle ekususeni ukungcola kanye nokungcola emanzini futhi ngokuvamile isebenza kangcono emanzini abandayo kune-alum. Cishe u-93% we-ferric chloride usetshenziswa ekuhlanzweni kwamanzi, okungukuthi amanzi angcolile, indle, amanzi okupheka kanye namanzi okuphuza. I-ferric chloride isetshenziswa kakhulu ngesimo esiqinile njengesixazululo sokwelashwa kwamanzi kanye namanzi angcolile.

Ukusetshenziswa kwe-ferric chloride ekuphatheni amanzi:

1. Ukujiya kanye Nokujiya: Enye yezindlela eziyinhloko zokusebenzisa i-ferric chloride ekuphatheni amanzi iwukuba yi-coagulant. Uma ingezwa emanzini, i-ferric chloride isabela namanzi ukuze ikhiqize i-ferric hydroxide bese kuthi lokhu kugwinye izinhlayiya ezilengayo, izinto eziphilayo, kanye nokunye ukungcola ukuze kwakheke izinhlayiya ezinkulu nezisindayo ezibizwa ngokuthi ama-floc. Lawa ma-floc angahlala kalula ngesikhathi senqubo yokuthuthwa noma yokuhlunga, okuvumela ukususwa kokungcola emanzini.

2. Ukususwa kwe-Phosphorus: I-Ferric chloride isebenza kahle kakhulu ekususeni i-phosphorus emanzini. I-Phosphorus iyisakhi esivamile esitholakala emanzini angcolile, futhi amazinga aphezulu angaholela ekukhuleni kwe-eutrophic ezindaweni zamanzi ezitholayo. I-Ferric chloride yakha ama-complex anganyibiliki nge-phosphorus, angasuswa ngemvula noma ngokuhlunga, okusiza ukunciphisa amazinga e-phosphorus emanzini.

3. Ukususwa Kwensimbi Enzima: I-ferric chloride isetshenziselwa futhi ukususa izinsimbi ezisindayo, njenge-arsenic, i-lead, kanye ne-mercury, emanzini. Lezi zinsimbi zingaba nobuthi obukhulu futhi zibe yingozi enkulu empilweni uma zikhona emanzini okuphuza. I-ferric chloride yakha ama-hydroxide ensimbi angancibiliki noma ama-oxychloride ensimbi, angasuswa ngezinqubo zemvula noma zokuhlunga, okunciphisa ngempumelelo ukugcwala kwezinsimbi ezisindayo emanzini.

4. Ukususwa Kombala Nephunga: I-Ferric chloride iyasebenza ekususeni amakhemikhali abangela umbala nephunga emanzini. I-oxidize amakhemikhali e-organic abangela umbala nephunga, iwahlukanise abe izinto ezincane, ezingafaneleki kangako. Le nqubo isiza ekuthuthukiseni ikhwalithi yobuhle bamanzi, okwenza afaneleke kakhulu ekuphuzeni, ezimbonini, noma ezinhlosweni zokuzijabulisa.

5. Ukulungiswa kwe-pH: Ngokulawula i-pH, i-ferric chloride ingenza ngcono ukusebenza kwezinye izinqubo zokwelapha, njengokujiya, ukugoba, kanye nokubulala amagciwane. Uhla lwe-pH olufanele lungasiza ekudaleni izimo ezifanele zokususa ukungcola kanye nokungcola emanzini.

6. Ukulawulwa Komkhiqizo Ongasuswanga Kumagciwane: I-ferric chloride ingasiza ekulawuleni ukwakheka kwemikhiqizo engasuswanga kumagciwane (ama-DBP) ngesikhathi sokwelashwa ngamanzi. Uma isetshenziswa kanye nezibulala-magciwane ezifana ne-chlorine, i-ferric chloride inganciphisa ukwakheka kwe-DBP njenge-trihalomethanes (ama-THM) kanye ne-haloacetic acids (ama-HAA), okungaba yizimbangela zomdlavuza. Lokhu kuthuthukisa ukuphepha kanye nekhwalithi yamanzi okuphuza iyonke.

7. Ukususwa Kwamanzi Odaka: I-ferric chloride isetshenziswa nasezinqubweni zokususwa kwamanzi odaka ezitshalweni zokuhlanza amanzi amdaka. Iyasiza ekulungiseni udaka ngokukhuthaza ukwakheka kwama-floc amakhulu, aminyene, ahlala ngokushesha futhi akhiphe amanzi ngendlela ephumelelayo. Lokhu kuphumela ekusebenzeni ngcono kokususwa kwamanzi kanye nokwehla kwevolumu yodaka, okwenza kube lula futhi kungabizi kakhulu ukuphatha nokulahla udaka.

I-Ferric Chloride idlala indima ebalulekile ezicini ezahlukene zokwelashwa kwamanzi, okuhlanganisa ukujiya, ukususwa kwe-phosphorus kanye nensimbi esindayo, ukususwa kombala nephunga, ukulungiswa kwe-pH, ukulawulwa komkhiqizo obulala amagciwane, kanye nokususwa kodaka. Ukuguquguquka kwayo kanye nokusebenza kwayo kuyenza ibe yikhemikhali ebalulekile ekwelapheni amanzi okuphuza kanye namanzi angcolile, okusiza ukuqinisekisa ukuphepha, ikhwalithi, kanye nokusimama kwemithombo yamanzi.
