Environmental difficulties as a result of the build-up of phosphates in waters, and by way of the disposal of huge volumes of sludges from physical-chemical approaches, have elevated the curiosity in phosphorus elimination from wastewaters using complex organic methods that use very little chemical ingredients. subject matters mentioned variety from the elemental microbiology and biochemistry of the improved organic elimination of phosphate, to useful full-scale plant studies with phosphorus removing and sludge dealing with from such approaches

Anoxic phosphorus removal, however, has been shown to be possible at high denltrlflcatlon rates. Denltrlflcatlon rates, In turn, have been shown to be enhanced by high F/M operation. This leads to the conclusion that nutrient removal systems should be operated at the highest F/M and the lowest SRT that permit nitrification.
