This paper presents performance experiences from the operation of a large SBRfacility in Nowy Targ, Poland. The plant has been in operation since 1995, and a number ofinvestigations have contributed to the evaluation of the operating conditions at the NowyTarg plant. The plant was designed for treating municipal and industrial wastewater fromabout 150,000 person equivalents. The plant receives chromium rich wastewater from almost400 small and medium-sized tanneries in the area. Although the Cr concentration sometimesexceeds 20 ppm in the combined incoming wastewater, the nutrient removal as well asorganic removal has proven to be very good. The possible effect of Cr acting as a precipitantfor phosphorus is also addressed. The influence of water temperature on the nitrogenperformance is clearly demonstrated by the results. The prevailing low water temperaturehas affected but not inhibited the nitrogen removal. The phosphorus removal as found in thisinvestigation suggests an advanced biological removal; however the impact of a possibleprecipitation by Cr is addressed.
