Toelichting (Engels) Management of the aeration length in a sequencing batch reactor (SBR) can improve N-removal by minimising the amount of organic substrate that is oxidised aerobically. This study investigates the long-term effect of aeration control on N-removal via simultaneous nitrification and denitrification (SND) by a mixed culture in a 2 L acetate-fed SBR, using PHB as the electron donor for denitrification. The reactor was operated continuously with automated termination of the aerobic phase after ammonium depletion, using the specific oxygen uptake rate (SOUR) as the control parameter

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
