Mokhoa oa ts'ebetso oa polyaluminium chloride:
Polyaluminium chlorideke inorganic coagulant e hlahisoang ke karabelo ea aluminium hydroxide le hydrochloric acid. Hangata e sebelisoa e le flocculant lits'ebetsong tsa metsi a masepala le indasteri.
Polyaluminium chloride electrostatically adsorb le ho kopana le fluoride ion ho etsa mefuta e fapaneng ea li-complexes tse tsitsitseng. Sena se tsoela pele ho theha le ho fokotsa aluminium fluoride e sa keneng.
