Iron (III) sulphate is used as a coagulant in water treatment, helping small particles bind together. Aluminium sulphate is also used, but fears of toxicity have led to the iron salt being preferred.
Mass poisoning like what happened at Camelford in Cornwall due to incorrect application of aluminium sulphate is unlikely with iron salts, they are less toxic and will colour the water.
