Abstract
|
|
|
|
| In this study, an onsite pilot sequencing batch reactor (SBR) of 450 L was operated at a local Flemish slaughterhouse in two consecutive periods. During period I, nitrogen removal via nitritation/denitritation (Nit/DNit) was achieved by the use of an innovative startup strategy without seed sludge and subsequently maintained by the use of aeration phase length control based on the oxygen uptake rate (OUR). In period II, the operational strategy was modified. In order to obtain Nit/DNit granular sludge (GS), an anaerobic (feast) feeding was introduced followed by a dynamic controlled (OUR‐based) aerobic (famine) reaction step. |
