A pumpable dispersion for water-purifying purposes contains iron (II) sulphate, the iron (II) sulphate being dispersed in a water phase having a dispersing agent comprising bentonite. The best dispersion properties are obtained with bentonite contents of 1-2% and with Fe<3><+> ions present in the composition. The amount of FeSO4 heptahydrate present may be about 80% of the composition, The invention also relates to a method for producing the composition. |
