  • Method of controlling the phosphorus concentration in biological wastewater purification plants
    Patent number: 6241888
    Abstract: The invention relates to a method of controlling a biological wastewater purification plant, in which the wastewater is aerated in an activation tank in the presence of an activated sludge and, to influence the properties of the activated sludge, phosphorus is added under controlled concentration, which comprises measuring the phosphorus concentration in the activated sludge for the control of the phosphorus addition and controlling the phosphorus addition in such a manner that the phosphorus concentration in the activated sludge is greater than or equal to a lower limit and is less than or equal to an upper limit. By means of the method according to the invention, the effluent values of a biological wastewater purification plant can be optimized and the limit values in the effluent of a wastewater purification plant prescribed by the authorities can be complied with better than hitherto.
