In wastewater treatment, aluminum sulfate can be used to polymerize phosphorus and suspended solids, and then the resulting flocs are deposited in a sedimentation tank or filtered out in a gravity filter. In drinking water applications, aluminum sulfate is used as a coagulant to neutralize the flocculation of raw water by charge, remove turbidity, and suspend solids.
