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.
