 abstract={The paper presents preliminary results of the research on the efficiency nitrogen removal in a hybrid sequencing batch reactor MBSBBR operating at low dissolved oxygen (DO) concentration ranging between 0,5 and 2 mg O_2/l. The study was carried out in a pilot scale model of SBR with a total volume of 35 liters, filled with carrier media up to the volumetric ratio 7,5 % of the fill volume.},
 abstract={A high efficiency of COD removal, obtained at DO concentration of 0,5--1,0 mg O_2/l, creates possibilities for a substantial reduction of exploatation costs for wastewater treatment plants on MBSBBR reactors. The analysis of the influence of a preset DO level on nitrogen transformation processes was found that together with an increase of DO concentration in the aerobic phases of the cycle an increase of the nitrification rate and decrease of the simultaneous denitrification rate can be observed.},
 abstract={The highest efficiency of nitrogen compounds removal was reached at DO concentration of 1,0--1,5 mg O_2/l. The conducted survey has confirmed that a DO concentration is one of the criterion-parameters for the process of simultaneous denitrification in aerobic phases.},
