Aluminium sulfate (alum) | Australian Drinking Water Guidelines
Aluminium sulfate (alum) is a general purpose coagulant that is used in water treatment to remove turbidity, natural organic matter (NOM) (including colour), microorganisms and many inorganic chemicals. Removal of NOM reduces the formation of disinfection by-products, because it removes the organic precursors of the by-products.

Coagulation of polyvinyl chloride microplastics by ferric and aluminium
The maximum MP removal accompanied by sufficiently low Fe/Al residuals and the lowest coagulant demand was reached by using ferric sulphate at 20 mg L −1 and pH 7 or aluminium sulphate at 40 mg L −1 and pH 7. The conditions under which coagulation was the most effective for MP removal indicated that adsorption onto metal hydroxide ...
