The aim of this paper is to present the results of an optimisation process of a municipal wastewater treatment plant. The plant was designed to be capable of biological excess phosphorous removal though effluent phosphorous concentrations were above the limit value for several occasions. In the summer period the total nitrogen concentration was also higher than required. It was examined how the adjustment of volume fractions contribute to effluent quality and the optimal ratios were determined by use of dynamic simulation techniques. The aerobic volume fraction was not altered only the two un-aerated phases were modified. The results showed that the anaerobic volume fraction could be lowered up to 11.5 % concluding the anoxic ratio to be 34.5 %.
