Phophorus can be removed from wastewater either by chemical addition or by biological uptake by specialised bacteria who have such properties that they can be selected for by proper choice of technology. By a sequence of anaerobic and anoxic or aerobic conditions the bacteria are exposed to such condition that they get a favourable situation and will proliferate. In doing so they develop a high intracellular P-content, by which the P is removed from the wastewater with the excess sludge. The aim is to developed a better understanding of the mechanisms of P-uptake and -release in order to better design and control the process in practise.
