Yini i-forric chloride esetshenziselwa ukwelashwa kwamanzi?

I-Ferric Chlorideiyingxenye yamakhemikhali ngeFomula FecL3. Isetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi njenge-coagulant ngenxa yokusebenza kwayo ekususeni ukungcola kanye nokungcola emanzini futhi ngokuvamile kusebenza kangcono emanzini abandayo kune-alum. Cishe ama-93% we-Ferric Chloride asetshenziswa ekwelashweni kwamanzi, okungukuthi i-wastewater, indle, amanzi okupheka namanzi okuphuza. I-Ferric Chloride isetshenziswa ikakhulukazi ngefomu eliqinile njengesixazululo samanzi namanzi amdaka.

Ukusetshenziswa kwe-Ferric Chloride ekuthini ukwelashwa kwamanzi:

1 Uma kungezwe emanzini, i-Ferric Chloride iphendula ngamanzi ukukhiqiza i-ferric hydroxide futhi ama-adsorbs asungula izinhlayiya, izinto eziphilayo, nokunye ukungcola ukwakha ama-flocs. Lawa ama-flocs angavele axazulule kalula ngesikhathi sedimentation noma izinqubo zokuhlunga, evumela ukususwa kokungcola emanzini.

2. Ukususwa kwePhosphorus: I-Ferric Chlority isebenza ngempumelelo ekususeni iPhosphorus emanzini. I-phosphorus yizakhi ezivamile ezitholakala emanzini angcolile, futhi amazinga ngokweqile angaholela ekutholeni i-eutrophication ekutholeni imizimba yamanzi. I-Ferric Chloride ikhipha izakhiwo ezingafakwanga nge-phosphorus, ezingasuswa ngokuhamba kwezulu noma ukufombula, zisiza ukunciphisa amazinga e-phosphorus emanzini.

3. Ukukhishwa kwensimbi esindayo: I-Ferric Chloride nayo isetshenziselwa ukususa izinsimbi ezisindayo, njenge-arsenic, ukuhola, ne-mercury, kusuka emanzini. Lezi zinsimbi zingaba nobuthi kakhulu futhi zibeke izingozi zempilo ezinkulu zempilo uma zikhona emanzini okuphuza. I-Ferric Chloride ikhipha ama-infoluble metal hydroxides noma insimbi oxychlorides, engasuswa ngezinqubo zemvula noma izinqubo zokuhlunga, ukunciphisa ngokuphumelelayo ukugcwala kwezinsimbi ezisindayo emanzini.

4. Ukususwa kombala kanye nephunga: I-Ferric Chloride iyasebenza ekususeni imibala nophunga obangela iphunga emanzini. I-It oxidizes arganic compound ebhekele umbala nephunga, lizephula libe yizinto ezincane, ezingathandeki. Le nqubo isiza ukuthuthukisa ikhwalithi yamanzi yobuhle, okwenza ilungele ukuphuza, izimboni, noma zokuzijabulisa.

I-5. Ukulungiswa kwe-PH: Ngokulawula i-PH, i-Ferric Chloride ingakhulisa ukusebenza kwezinye izinqubo zokwelashwa, njengokuhlangana, i-floccution, kanye negciwane. Ibanga elifanelekile le-PH lungasiza ukudala izimo ezifanele zokususwa kokungcola nokungcola kusuka emanzini.

I-6 Uma isetshenziswa ngokubambisana nezimpawu ze-disinfectants ezifana ne-chlorine, i-forric chloride inganciphisa ukwakheka kwama-DBP anjenge-trihalometanes (thms) nama-halopetic acids (haas), okungama-carcinogens angaba khona. Lokhu kuthuthukisa ukuphepha okuphelele kanye nekhwalithi yamanzi okuphuza.

7 Kuyasiza ukufaka isimo i-sludge ngokuqhakambisa ukwakheka kwama-flocs amakhulu, ama-denser, axazulule ngokushesha futhi akhulule amanzi kahle. Lokhu kuphumela ekusebenzeni okwenziwe ngcono kwezokwenziwa kanye nokunciphisa ivolumu ye-sludge, okwenza kube lula futhi kungabizi kakhulu ukuphathwa nokulahla i-sludge.

I-Ferric Chloride idlala indima ebalulekile ezintweni ezahlukahlukene zokwelashwa kwamanzi, okubandakanya ukuhlangana, i-phosphorus kanye nokususwa kwensimbi, ukususwa kombala, ukulungiswa kwe-ph, ukulungiswa kwe-slidege. Ukusebenza kwayo kwayo kanye nokusebenza kahle kwenza kube ngamakhemikhali abalulekile ekwelashweni kwawo womabili amanzi okuphuza namanzi amdaka, asiza ekuqinisekiseni ukuphepha, ikhwalithi, nokusimama kwemithombo yamanzi.
