Jwalo ka moetapele lefapheng la kalafo ya metsi,hexametaphosphate ea sodiume bapala karolo ea bohlokoa haholo ho ntlafatseng boleng ba metsi. Taba ea pele, e ka tlosa lintho tse emisitsoeng le litšila tsa colloidal ka katleho metsing, 'me ea khothaletsa pula le karohano ea litšila ka ho etsa li-polymer tse kholo. Tšobotsi ena e bohlokoa haholo kalafong ea metsi a litšila a indasteri le likhoerekhoere tsa malapeng. Taba ea bobeli, sodium hexametaphosphate, ka bokhoni ba eona bo matla ba ho rarahana, e kopana haufi-ufi le li-ion tsa calcium le magnesium metsing a thata, e thibela ka katleho ho thehoa ha sekala, 'me e bohlokoa bakeng sa tlhokomelo ea litsamaiso tsa phepelo ea metsi a chesang, liboiler, litora tse pholileng le lisebelisoa tse ling. Ho feta moo, e ka boela ea fetola boleng ba pH ba metsi, ka ho lokolla li-ion tsa phosphate le li-ion tsa sodium, le ho arabela ka li-ion tsa hydrogen le li-ion tsa hydroxide metsing ho netefatsa boleng bo tsitsitseng ba metsi le ho fihlela litlhoko tse fapaneng tsa ts'ebeliso. Joaloka mofani oa sodium hexametaphosphate, Aojin Chemical e tla arolelana le uena kajeno ts'ebeliso e khethehileng ea sodium hexametaphosphate kalafong ea metsi:
1. Sethibela-mafome: Sodium hexametaphosphate e ka kopana le li-ion tsa tšepe (tse kang calcium le magnesium) ka metsing ho thibela ho hola ha liphaephe le lisebelisoa, ka hona ho fokotsa ho hola le ho hola. E sebelisoa haholo lits'ebetsong tsa metsi tse potolohang tsa indasteri.
2. Sefafatsi: Sodium hexametaphosphate e ka hasanya dikarolwana tse leketlileng mme ya di thibela ho dula, ka hona ya ntlafatsa bokgoni ba ho hlwekisa dikgwerekgwere. Tshebetsong ya ho hlwekisa dikgwerekgwere, e ka thibela seretse ho dula le ho ntlafatsa ditlamorao tsa kalafo.
3. Moemeli oa Chelating: E kopana le li-ion tsa tšepe e boima ho fokotsa chefo le ts'ebetso ea tsona, 'me e sebelisetsoa ho phekola metsi a litšila a nang le tšepe e boima le ho fokotsa tšilafalo ea tšepe e boima.
4. Senolofatsang: Se arabela le li-ion tsa calcium le magnesium ka metsing ho thibela ho thehwa ha sekala, se loketse liboiler le litsamaiso tsa metsi a pholileng ho thibela ho thehwa.
5. Coagulant: E khothalletsa ho hoama ha likaroloana tse emisitsoeng, e nolofalletsa pula kapa ho sefa, 'me e ntlafatsa phello ea karohano ea metsi a tiileng. E sebelisoa haholo lits'ebetsong tsa ho hoama le ho sekama ha mobu.
6. Taolo ea pH: lokisa boleng ba pH ea likhoerekhoere le ho ntlafatsa maemo a kalafo. E loketse lits'ebetso tsa kalafo tse hlokang boleng bo itseng ba pH, joalo ka likarabelo tsa ho se nke lehlakore
7. Mochini o tlosang phosphorus: O kopana le phosphates ho etsa marotholi a sa qhibiliheng, o tlosa phosphorus, mme o sebediswa ho laola meya ya metsi a eutrophic
8. Maemo a itseng a tshebediso ya sodium hexametaphosphate kalafong ya metsi a kenyeletsa:
Sistimi ea metsi e potolohang indastering: E le thibelo ea mafome, e fokotsa mafome le ho hola
Kalafo ea metsi a litšila: E le sesebelisoa sa ho qhala le ho kopanya ho ntlafatsa katleho ea kalafo
Kalafo ea metsi a litšila a tšepe e boima: E le sesebelisoa sa ho fokotsa tšilafalo ea tšepe e boima
Sistimi ea boiler le ea metsi a pholileng: E le sesebelisoa sa ho nolofatsa ho thibela ho thehoa ha sekala
Mokhoa oa ho kopanya le ho sedimenta: E le coagulant ho ntlafatsa phello ea karohano ea metsi a tiileng
Karabelo ea Neutralization: Joaloka molaoli oa pH, ntlafatsa maemo a kalafo
Kalafo ea libaka tsa metsi tse se nang mafura: E le sesebelisoa sa ho tlosa phosphorus, laola bongata ba phosphorus
Jwalo ka moemedi ya sebetsang hantle wa kalafo ya metsi,hexametaphosphate ea sodiumE na le lits'ebetso tse ngata masimong a mangata. E thibela ka katleho ho thehoa ha lihlahisoa tsa sekala le tsa mafome ka ho rarahana, ho hasana le ho buffer, e sireletsa lisebelisoa le liphaephe, 'me e ntlafatsa boleng ba metsi le ts'ebetso ea lisebelisoa.
