Abstract This research studies the effect of the widely used coagulant ferric chloride on the activated sludge sedimentability through a vast array of hindered settling tests considering different application modes and a wide range of reagent doses. Direct application of ferric chloride improved the hindered settling velocity (up to twice the settling velocity of the activated sludge with no coagulant addition), but sharply decreased the pH to levels where the biological process was unfeasible (pH
