Ho etsahala'ng ha aluminium sulfate e arabela le metsi?

Sulfate ea aluminium, e emeloang ka lik'hemik'hale e le Al2(SO4)3, ke kristale e tšoeu e tiileng e sebelisoang hangata lits'ebetsong tsa kalafo ea metsi. Ha aluminium sulfate e arabela le metsi, e feta hydrolysis, e leng karabelo ea lik'hemik'hale eo ho eona limolek'hule tsa metsi li arolang motsoako ho li-ion tsa oona. Karabelo ena e bapala karolo ea bohlokoa lits'ebetsong tse fapaneng, haholo-holo tlhoekisong ea metsi.

Sehlahisoa sa mantlha sa karabelo ena ke aluminium hydroxyl complex. Aluminium hydroxyl complex e bohlokoa haholo kalafong ea metsi, kaha e thusa ho tlosa litšila metsing. Aluminium hydroxyl complex e na le tjhaja e ngata, 'me ha e thehoa, e atisa ho tšoasa le ho hohlana ha likaroloana tse leketlileng, tse kang letsopa, seretse le lintho tse phelang. Ka lebaka leo, litšila tsena tse nyenyane li fetoha likaroloana tse kholo le tse boima, e leng se etsang hore ho be bonolo hore li lule ka ntle ho metsi.

Asiti ea sulfuric e hlahisoang karabelong e lula e le tharollong 'me e kenya letsoho ho asiti eohle ea sistimi. Asiti e ka fetoloa ha ho hlokahala, ho latela litlhoko tse ikhethileng tsa ts'ebetso ea kalafo ea metsi. Ho laola pH ho bohlokoa bakeng sa ho ntlafatsa katleho ea ts'ebetso ea ho kopana le ho flocculation. Hape ho fokotsa alkalinity ea metsi. Haeba alkalinity ea metsi a letamo ka boeona e le tlase, joale NaHCO3 e hloka ho eketsoa ho eketsa alkalinity ea metsi.

Karabelo pakeng tsa aluminium sulfate le metsi e sebediswa hangata mehatong ya ho kopanya le ho phaphamala ha dimela tsa kalafo ya metsi. Ho kopanya ho kenyeletsa ho sitisa dikarolwana tse leketlileng, ha ho phaphamala ho kgothaletsa ho kopana ha dikarolwana tsena hore e be di-floc tse kgolo, tse ka rarollehang habonolo. Ditshebetso tsena ka bobedi di bohlokwa bakeng sa ho tlosa ditshila le ho hlakisa metsi.

Ho bohlokoa ho hlokomela hore tšebeliso ea aluminium sulfate kalafong ea metsi e hlahisitse matšoenyeho a tikoloho ka lebaka la ho bokellana ha aluminium libakeng tsa tlhaho tsa metsing. Ho fokotsa matšoenyeho ana, tekanyo e nepahetseng le tlhokomelo lia hlokahala ho netefatsa hore mahloriso a aluminium metsing a phekotsoeng a fihlela maemo a taolo.

Qetellong, ha aluminium sulfate e arabela le metsi, e feta hydrolysis, e hlahisa aluminium hydroxide le sulfuric acid. Karabelo ena ea lik'hemik'hale ke ea bohlokoa lits'ebetsong tsa kalafo ea 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 e sebetsang ea metsi ha ka nako e ts'oanang ho fokotsa tšusumetso ea tikoloho.
