The phosphorus removing microorganisms grow relatively slowly but generally faster than the nitrifying bacteria. However, in such a configuration biological phosphorus removal is adversely affected if the aerobic zone is large enough to allow nitrifying bacteria to grow.

National Research Council 1993 Managing Wastewater in Coastal Urban Areas, National Academy Press, Washington, D. Under these conditions, the capability of heterotrophic microorganisms to metabolize organic matter is dramatically reduced.

Nitrification Nitrification is the biological conversion of ammonia-nitrogen to nitrate-nitrogen. 2 mg of alkalinity as CaCO 3 for each mg of NO 3-N produced. The optimum pH for growth of the nitrifying bacteria is generally about 7. Many systems exist which exploit this feature to encourage an extensive degree of nitrification and denitrification within the system.

In the process illustrated in Figure 3, nitrification the first step in a biological removal process occurs in the first aerobic zone.

This can be an important issue if certain industrial wastewaters are being treated Sedlak, 1991. The mechanisms operating in biological nitrogen removal systems are discussed first, allowed by the mechanisms operating in biological phosphorus removal systems. This material will generally be flocculated and incorporated into the biological treatment system mixed liquor and subsequently removed from the process with the waste sludge.

Nitrogen removal will occur by this mechanism in BNR systems, just as it occurs in any biological wastewater treatment system.

Table 1 summarizes the impacts of nutrient discharges on receiving waters. A frequently used correlation is that developed by Burdick, Stensel, and Refling 1982. However, as also illustrated in Figure 6, when the phosphorus accumulating microorganisms subsequently pass into the aerobic zone where oxygen is provided to allow aerobic metabolism, they oxidize the stored organic matter and generate energy which is used to take up phosphate from solution and store is as polyphosphate.

Extended fundamental and full-scale research has been carried out into the bio-P process and the state-of-the-art is described in this report. Some of the most significant ones include dissolved oxygen DOpH, and the presence of inhibitors.

Different process options may also simply represent different approaches to accomplish the same objectives.
