Abstract

Description de compositions de floc pouvant être utilisées dans un procédé de purification deau, p. ex., dans un procédé pour purifier le drainage minier acide. Dans un mode de réalisation, une composition de floc contient un cation oléosoluble, un ion métallique, un hydroxyde ou un oxyde, et un anion de formule {(R4N+)x(N(II)n(OH-)z(SO4 2-)w}m dans le cas dions métalliques divalents ou {(R4N+)x(M(III))y(OH-),(SO4 2)w}q dans le cas dions métalliques trivalents.
