Lenane la boleng ba PAC (polyaluminium chloride)
Ke matšoao afe a mararo a bohlokoa ka ho fetisisa a boleng ba PAC (polyaluminium chloride)? Letsoai, boleng ba PH, le likahare tsa alumina tse khethollang boleng ba polyaluminium chloride ke matšoao a mararo a bohlokoahali a boleng ba polyaluminium chloride.
1. Letsoai.
Tekanyo ea hydroxylation kapa alkalization ea mofuta o itseng ho PAC (polyaluminium chloride) e bitsoa degree of basicity kapa alkalinity. Ka kakaretso e hlalosoa ka tekanyo ea molar ea aluminium hydroxide B=[OH]/[Al] peresente. Letsoai ke e 'ngoe ea matšoao a bohlokoa ka ho fetisisa a polyaluminium chloride, e amanang haufi-ufi le phello ea flocculation. Ha metsi a sa hloekisoa a phahame 'me letsoai le le holimo, ho na le phello e ntle ea flocculation. Ho akaretsa, har'a mefuta e mengata ea metsi a tala a 86 ~ 10000mg/L, letsoai le phahameng la polyaluminium chloride ke 409 ~ 853, 'me litšobotsi tse ling tse ngata tsa polyaluminium chloride li amana le letsoai.
2. pH boleng.
PH ea tharollo ea PAC (polyaluminium chloride) le eona ke pontšo ea bohlokoa. E emela palo ea OH- sebakeng se lokolohileng tharollong. Boleng ba pH ba polyaluminium chloride hangata bo eketseha ka keketseho ea mantlha, empa bakeng sa lino tse nang le mefuta e fapaneng, ha ho na kamano e tsamaellanang lipakeng tsa pH le motheo. Mekelikeli e nang le matsoai a tšoanang a letsoai a na le litekanyetso tse fapaneng tsa pH ha mahloriso a fapane.
3. Likahare tsa Alumina.
Likahare tsa alumina ho PAC (polyaluminium chloride) ke tekanyo ea likarolo tse sebetsang tsa sehlahisoa, se nang le kamano e itseng le boima bo lekanang ba tharollo. Ha re bua ka kakaretso, ha palo e lekanyelitsoeng e le kholoanyane, ho na le lisebelisoa tse phahameng tsa alumina. Viscosity ea polyaluminium chloride e amana le litaba tsa alumina, 'me viscosity e eketseha ka ho eketseha ha litaba tsa alumina. Tlas'a maemo a tšoanang le mahloriso a tšoanang a alumina, viscosity ea polyaluminium chloride e tlase ho feta ea aluminium sulfate, e leng molemo ho lipalangoang le tšebeliso.
