On-line estimation of the aerobic phase length for partial nitrification processes in SBR based on features extraction and SVM classification
(Elsevier B.V., 2018)
We present a strategy for the on-line estimation of the aerobic reaction phase length for a partial nitrification process with pH and dissolved oxygen closed-loop control. To overcome existing drawbacks associated to partial ...
Advanced strategies to improve nitrification process in sequencing batch reactors - A review
(Academic Press, 2018)
The optimization of biological nitrogen removal (BNR) in sequencing batch reactors has become the aim of researchers worldwide in order to increase efficiency and reduce energy and operating costs. This research has focused ...
Active biomass estimation based on ASM1 and on-line OUR measurements for partial nitrification processes in sequencing batch reactors
(Elsevier, 2020)
The main challenge for partial nitrification is to reach stable nitrite accumulation, which strongly depends on the nitrite-oxidizing bacteria (NOB) growth in the reactor. The on-line estimation of active biomass may enhance ...
Supervisory control system to enhance partial nitrification in an activated sludge reactor
(ELSEVIER SCIENCE SA, 2009)
Nitrapyrin effectiveness in reducing nitrous oxide emissions decreases at low doses of urea in an Andosol
(2021)
In the tropics, frequent nitrogen (N) fertilization of grazing areas can potentially increase nitrous oxide (N2O) emissions. The application of nitrification inhibitors has been reported as an effective management practice ...
