Ho etsahala'ng ha aluminium sulphate e kopana le metsi?

Aluminium sulfate, lik'hemik'hale tse emetsoeng e le Al2 (SO4) 3, ke kristale e tšoeu e tiileng e atisang ho sebelisoa mekhoeng ea ho hloekisa metsi.Ha aluminium sulfate e kopana le metsi, e kenella ka hydrolysis, e leng ts'ebetso ea lik'hemik'hale moo limolek'hule tsa metsi li arolang motsoako hore e be li-ion tsa oona.Karabelo ena e phetha karolo ea bohlokoa lits'ebetsong tse fapaneng, haholo-holo tlhoekisong ea metsi.

Sehlahisoa sa mantlha sa karabelo ena ke aluminium hydroxyl complex.Motsoako ona o bohlokoa ho hloekisa metsi, kaha o thusa ho tlosa litšila metsing.Aluminium hydroxyl complex e na le tefiso e phahameng ea tefiso, 'me ha e etsoa, ​​​​e atisa ho tšoasa le ho kopanya likaroloana tse emisitsoeng, tse kang letsopa, silt le lintho tse phelang.Ka lebaka leo, litšila tsena tse nyenyane li fetoha likaroloana tse khōloanyane le tse boima, ho etsa hore ho be bonolo hore li tsoe ka metsing.

Asiti ea sulfuric e hlahisoang karabelong e lula e le tharollo mme e kenya letsoho ho acidity e akaretsang ea sistimi.Asiti e ka fetoloa kamoo ho hlokahalang, ho itšetlehile ka litlhoko tse khethehileng tsa mokhoa oa ho hloekisa metsi.Ho laola pH ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea coagulation le flocculation process.E boetse e fokotsa alkalinity ea metsi.Haeba alkalinity ea metsi a letamo ka boeona e le tlaase, joale NaHCO3 e hloka ho eketsoa ho eketsa alkalinity ea metsi.

Boitšoaro pakeng tsa aluminium sulfate le metsi hangata bo sebelisoa mehatong ea ho kopanya le ho phalla ha limela tsa ho hloekisa metsi.Coagulation e kenyelletsa ho senyeha ha likaroloana tse emisitsoeng, ha flocculation e khothalletsa ho bokellana ha likaroloana tsena hore e be li-flocs tse khōloanyane, tse tsitsitseng habonolo.Mekhoa ena ka bobeli e bohlokoa bakeng sa ho tlosa litšila le ho hlakisa metsi.

Ke habohlokoa ho hlokomela hore tšebeliso ea aluminium sulfate ho hloekisa metsi e hlahisitse matšoenyeho a tikoloho ka lebaka la ho bokellana ha aluminium tikolohong ea metsing.Ho fokotsa mats'oenyeho ana, ho beha litekanyetso le ho beha leihlo ka nepo ho bohlokoa ho netefatsa hore likhakanyo tsa aluminium metsing a hloekisitsoeng li fihlela litekanyetso tsa taolo.

Qetellong, ha aluminium sulfate e arabela ka metsi, e kenella ka hydrolysis, e hlahisa aluminium hydroxide le sulfuric acid.Karabelo ena ea lik'hemik'hale ke ea bohlokoa mekhoeng ea ho hloekisa metsi, moo aluminium hydroxide e sebetsang e le coagulant ho tlosa litšila tse emisitsoeng metsing.Taolo le tlhokomelo e nepahetseng lia hlokahala ho netefatsa tlhoekiso ea metsi e sebetsang hantle ha ho ntse ho fokotsa tšusumetso ea tikoloho.
