In the present study the influence of hydraulic retention time (HRT) in SBR and sludge age (SRT) on the effectiveness of nitrogen removal from leachate was investigated. Two series were performed. In each series, experiments were carried out in four SBR operated in parallel at HRT 12, 6, 3 and 2d, respectively. Each series differed in sludge age. In series 1, SRT decreased from 51 to 17d with shortening...
In the study, the efficiency of landfill leachates treatment by activated sludge in anaerobic-aerobic conditions in sequencing batch reactors (SBR) was examined. The experiments were carried out in four series characterised by different hydraulic retention time in reactors (t = 12, 6, 3 and 2 days), which was obtained by increasing the volumetric change rate in a treatment cycle from 8.3 to 50%. ...
