The phosphate precipitation is partly triggered because of the addition of aluminium or iron salts while in the sand collector or inside the secondary wastewater treatment tank. The metallic-phosphate flocks which might be fashioned in the course of this secondary clarification are then taken out of the wastewater together with the activated sludge.
