Szukana fraza: [Abstract = "The efficiency of removing nitrogen compounds from sewage in the analysed treatment plant depended on the temperature of sewage and the quotient BOD5\/TKN. Even at the optimal ranges of BOD5\/TKN ratio temperature at 10 degrees Celsius nitrogen concentration in the treated wastewater was about 3 times higher than the limit value, and the removal efficiency of nitrogen varied between about 30 to 60%."]
