Effects of Sludge Retention Times on Nutrient Removal and Nitrous Oxide Emission in Biological Nutrient Removal Processes
Sludge retention time (SRT) is an important factor affecting not only the performance of the nutrient removal and sludge characteristics, but also the production of secondary pollutants such as nitrous oxide (N2O) in biological nutrient removal (BNR) processes. Four laboratory-scale sequencing batch reactors (SBRs), namely, SBR5, SBR10, SBR20 and SBR40 with the SRT of 5 d, 10 d, 20 d and 40 d, ...
متن کاملExternal nitrification in biological nutrient removal activated sludge systems.
A biological nutrient removal (BNR) activated sludge (AS) scheme incorporating external nitrification in a fixed media system is evaluated. A laboratory scale investigation of the scheme indicates that it holds considerable potential for BNRAS system intensification through major reduction in sludge age and oxygen demand and significant improvement in sludge settleability. Because the BNRAS sys...
متن کاملSludge Reduction and Biological Nutrient Removal by Ultrasound
Sludge produced in wastewater treatment plants (WWTPs) reaches around 1% of the wastewater volume treated whilst the processes for sludge handling and disposal represent from 20 to 60% of operating costs. It is widely recognised that sludge for disposal is one of the most critical issues today for WWTPs operators. The tendency of many countries seems to be aimed towards a biowaste prevention wh...
متن کاملEffects of integrated fixed film activated sludge media on activated sludge settling in biological nutrient removal systems.
Integrated fixed film activated sludge (IFAS) is an increasingly popular modification of conventional activated sludge, consisting of the addition of solid media to bioreactors to create hybrid attached/suspended growth systems. While the benefits of this technology for improvement of nitrification and other functions are well-demonstrated, little is known about its effects on biomass settleabi...
متن کاملNitrous Oxide Emission Depending on the Type of Electron Acceptor by a Denitrifying Phosphorus Removal Sludge
Denitrifying polyphosphate accumulating organisms (DNPAOs) are very promising for simultaneous nitrogen and phosphorus removal. While during denitrification, emission of a greenhouse gas, nitrous oxide (N2O), may occur. In this study, DNPAOs were enriched in a lab-scale reactor, and N2O emission was examined under different electron acceptor conditions. During the anoxic phase, with the uptake ...
