Phosphates are removed which has a chemical precipitation or flocculation process. The phosphate precipitation is partly activated via the addition of aluminium or iron salts inside the sand collector or from the secondary wastewater treatment tank. The metallic-phosphate flocks which are shaped in the course of this secondary clarification are then taken out of the wastewater along with the activated sludge. According to the method of Procedure, the phosphate may also be "fished" with the help of microorganisms from the wastewater. In such cases we speak of a Organic phosphorus elimination, that is, nonetheless, nevertheless not often applied.
