Intracellular Phosphorus

In this study the functions of the intracellular polyphosphate in the biological phosphorus removal process were investigated from biological point of view. The STS method was used for the determination of polyphosphate and the fractionation of the intracellular phosphorus compounds. The lowmolecular polyphosphate and the highmolecular polyphosphate can be determined separately in this method. The radiotracer experiments were performed in which 32P-labeled orthophosphate was used as a tracer. The chemical analyses of phosphorus and the radioactivity measurement were made simultaniously in the course of the anaerobic oxic process. From the results of a radiotracer experiment the mass transfer of phosphorus among the phosphorus compounds was calculated. It was suggested that the lowmolecular polyphosphate served as the energy source under the anaerobic conditions and that the highmolecular polyphosphate served as the phosphorus source for the growth reactions. Some models for the phosphorus transfer in the high phosphorus accumulating microorganisms were proposed.

Biological Phosphorus

While the mechanism of biological phosphorus removal (BPR) and the need for volatile fatty acids (VFA) have been well researched and documented to the point where it is now possible to design a plant with a very reliable phosphorus removal process using formal flow sheets, BPR is still observed in a number of plants that have no designated anaerobic zone, which was considered essential for phosphorus removal. Some examples are given in this paper. A theory is proposed and then applied to solve problems with a shortage of VFA in the influent of the Henderson NV plant. Mixed liquor was fermented in the anaerobic zone, which resulted in phosphorus removal to very low levels. This paper will discuss some of the background, and some case histories and applications, and present a simple postulation as to the mechanism and efforts at modelling the results.
