Phosphates are taken out which has a click here chemical precipitation or flocculation process. The phosphate precipitation is partly activated by the addition of aluminium or iron salts in the sand collector or while in the secondary wastewater treatment tank. The steel-phosphate flocks which might be shaped during this secondary clarification are then taken out of the wastewater along with the activated sludge.
