The phosphate precipitation is partly induced through the addition of aluminium or iron salts inside the sand collector or during the secondary wastewater treatment tank. The metallic-phosphate flocks which are shaped during this secondary clarification are then taken out with the wastewater together with the activated sludge. Based on the manner of operation, the phosphate can even be "fished" with the assistance of microorganisms within the wastewater.
