Ferric Chloride e sebelisetsoa eng kalafong ea metsi?

Ferric Chlorideke motsoako oa lik'hemik'hale o nang le foromo ea FeCl3. E sebelisoa haholo lits'ebetsong tsa kalafo ea metsi e le coagulant ka lebaka la katleho ea eona ea ho tlosa litšila le litšila metsing 'me ka kakaretso e sebetsa hantle metsing a batang ho feta alum. Hoo e ka bang 93% ea ferric chloride e sebelisoa kalafong ea metsi, ke hore, metsi a litšila, likhoerekhoere, metsi a phehang le metsi a nooang. Ferric chloride e sebelisoa haholo-holo ka mokhoa o tiileng e le tharollo ea phekolo ea metsi le metsi a litšila.

Tšebeliso ea ferric chloride kalafong ea metsi:

1. Ho Kopana le ho Tsamaisa: E 'ngoe ea mekhoa ea mantlha ea ferric chloride kalafong ea metsi ke ho ba coagulant. Ha e eketsoa metsing, ferric chloride e arabela le metsi ho hlahisa ferric hydroxide 'me ea morao e monya likaroloana tse emisitsoeng, lintho tse phelang le litšila tse ling ho etsa likaroloana tse kholoanyane, tse boima tse bitsoang flocs. Li-flocs tsena li ka lula habonolo nakong ea lits'ebetso tsa ho sefa kapa ho sefa, e leng se lumellang ho tlosoa ha litšila metsing.

2. Ho Tlosa Phosphorus: Ferric chloride e sebetsa hantle haholo ho ntsheng phosphorus metsing. Phosphorus ke phepo e tloaelehileng e fumanoang metsing a litšila, 'me maemo a feteletseng a ka lebisa ho eutrophication metsing a amohelang. Ferric chloride e etsa metsoako e sa qhibiliheng ka phosphorus, e ka tlosoang ka pula kapa ho sefa, e thusang ho fokotsa maemo a phosphorus metsing.

3. Ho Tlosa Tšepe e Boima: Ferric chloride e boetse e sebelisetsoa ho tlosa litšepe tse boima, tse kang arsenic, loto le mercury, metsing. Litšepe tsena li ka ba chefo haholo 'me tsa baka likotsi tse kholo tsa bophelo bo botle haeba li le teng metsing a nooang. Ferric chloride e etsa li-hydroxide tsa tšepe tse sa qhibiliheng kapa li-oxychloride tsa tšepe, tse ka tlosoang ka mekhoa ea pula kapa ea ho sefa, e leng se fokotsang ka katleho khatello ea litšepe tse boima ka metsing.

4. Ho Tlosa 'Mala le Monko o Mobe: Ferric chloride e sebetsa hantle ho tloseng metsoako e bakang 'mala le monko metsing. E oxidation ea metsoako ea tlhaho e ikarabellang bakeng sa 'mala le monko, e e arola hore e be lintho tse nyenyane, tse seng mpe hakaalo. Ts'ebetso ena e thusa ho ntlafatsa boleng ba botle ba metsi, e leng se etsang hore a lokele ho nooa, ho sebelisoa indastering, kapa boithabisong.

5. Phetoho ea pH: Ka ho laola pH, ferric chloride e ka ntlafatsa ts'ebetso ea lits'ebetso tse ling tsa kalafo, joalo ka ho hoama, ho flocculation, le ho bolaea likokoana-hloko. Mefuta e metle ea pH e ka thusa ho theha maemo a matle a ho tlosa litšila le litšila metsing.

6. Taolo ea Lihlahisoa tse ka Hare ho Libolaea: Ferric chloride e ka thusa ho laola ho thehoa ha lihlahisoa tse ka Hare ho Libolaea (DBPs) nakong ea phekolo ea metsi. Ha e sebelisoa hammoho le li-disinfectant tse kang chlorine, ferric chloride e ka fokotsa ho thehoa ha DBP tse kang trihalomethanes (THMs) le haloacetic acids (HAAs), e leng li-carcinogen tse ka bang teng. Sena se ntlafatsa polokeho le boleng ba metsi a nooang ka kakaretso.

7. Ho Ntša Metsi a Lerōle: Ferric chloride e boetse e sebelisoa lits'ebetsong tsa ho ntša metsi a lerōle lipolasing tsa phekolo ea metsi a litšila. E thusa ho lokisa seretse ka ho khothalletsa ho thehoa ha li-floc tse kholoanyane, tse teteaneng, tse lulang kapele le ho lokolla metsi ka katleho. Sena se fella ka ts'ebetso e ntlafetseng ea ho ntša metsi le ho fokotsa bongata ba seretse, e leng se etsang hore ho be bonolo le ho theko e tlase ho sebetsana le ho lahla seretse.

Ferric Chloride e bapala karolo ea bohlokoa likarolong tse fapaneng tsa kalafo ea metsi, ho kenyeletsoa ho hoama, ho tlosoa ha phosphorus le tšepe e boima, ho tlosoa ha 'mala le monko, ho lokisoa ha pH, taolo ea sehlahisoa se bolaeang likokoana-hloko, le ho tlosoa ha seretse. Ho tenyetseha ha eona le katleho ea eona li e etsa hore e be k'hemik'hale ea bohlokoa kalafong ea metsi a nooang le metsi a litšila, e thusang ho netefatsa polokeho, boleng le botsitso ba mehloli ea metsi.
