A New Factor of Control of Facilities for Biological Removal of Phosphates from Wastewater

Summary

A new technological indicator making it possible to improve the efficiency and stability of phosphates removal at the facilities of biological treatment of wastewater for biogenic elements – the periodicity of change of phosphates concentration in the end of the anaerobic technological zone – is described. The use of this indicator reflecting the activity of phosphate accumulating bacteria has been assumed as a basis of a new algorithm of control of treatment facilities using the technology of biogenic elements removal and led to improvement of the efficiency of phosphates removal by 1,5–1,7 times.
