Mofuta o nepahetseng oa pH oa polyaluminium chloride metsing a litšila a etsang pampiri
Neng Polyaluminium Chloride e sebelisetsoa ho phekola likhoerekhoere tsa ho etsa pampiri, mofuta o motle ka ho fetisisa oa pH o angoa ke lintlha tse ngata. Lithuto tse fapaneng le lits'ebetso tse sebetsang li fana ka mefuta e fapaneng hanyane, hangata lipakeng tsa 6 le 9. A latelang ke maemo a ikhethileng datang e fapaneng:
Letsoai ke e 'ngoe ea matšoao a mantlha a polyferric sulfate (PFS),' me e phahameng le e tlase e ama ka kotloloho ts'ebetso ea flocculation. Mokhoa o ikhethileng oa ts'usumetso le maemo a ts'ebeliso ke joalo ka
Tšusumetso e tobileng ea letsoai holim'a katleho ea flocculation
Bohlokoa ba litaba tsa aluminium ka polyaluminium chloride
Sebakeng sa ho hloekisa likhoerekhoere le Tlhoekiso ea Metsi, polyaluminium chloride ke flocculant e sebelisoang haholo le e sebetsang haholo. Har'a matšoao a fapaneng a ho lekola boleng le ts'ebetso ea polyaluminium chloride, ha ho pelaelo hore litaba tsa aluminium oxide ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa. E susumetsa haholo katleho, boholo ba ts'ebeliso, le katleho ea litšenyehelo tsa polyaluminium chloride.
Mokhoa oa ho lemoha Polyaluminium Chloride Content
E le coagulant ea bohlokoa tšimong ea phekolo ea metsi, ho fumanoa ha polyaluminium chloride (Pac) boleng bo lokela ho etsoa ho potoloha lits'oants'o tsa mantlha, ho kenyeletsoa litaba tsa alumina, letsoai, boleng ba pH le litaba tse sa keneng metsi, jj.
