Description:
Aluminium sulphate is used in water treatment for the coagulation of organic and mineral colloids prior to sedimentation and/or filtration. The alum destabilises fine colloidal suspensions and promotes the formation of conglomerations of this material bound in a chemical precipitate (called floc) which is able to be removed from the water by sedimentation, flotation and/or filtration.
