Biological phosphorus removal (BPR) is a microbiological process,
in which specific organisms are able to decrease the
amount of phosphorus in the activated sludge system more
than it is required for the growth of the organisms. Various
process configurations were created in the 1960s and 1970s in
the US and South Africa, such as PhoStrip and A/O [1]. Several
biochemical models have been developed to explain the
mechanisms of enhanced biological phosphorus removal
