Oxygen-limited autotrophic nitrification–denitrification (OLAND) in a rotating biological contactor treating high-salinity wastewater

Performance and Microbial Diversity in a Low-Energy ANF-WDSRBC System for the Post-Treatment of Decentralized Domestic Wastewater

“…The genus Thauera belonging to the class Betaproteobacteria was also detected in the activated sludge system [33]. Windey et al reported that Bacillus played important roles in denitrification [42]. In our study, TN removal efficiency in the ANF was much higher than in WDSRBC ( Figure 5), indicating that these genera might be key contributors to converting nitrate to nitrogen gas in ANF unit.…”

Review on the Fate and Mechanism of Nitrogen Pollutant Removal from Wastewater Using a Biological Filter

“…Compared with a traditional nitrification-denitrification process, OLAND requires lower oxygen consumption (63% lower), higher organic carbon degradation and removal efficiency, and lower operating cost [34]. De Clippeleir et al [80] demonstrated the possibility of obtaining fully autotrophic TN removal in the OLAND biofilter through a coupling of aerobic AOB and anoxic ammonium oxidizing or anammox bacteria (AnAOB) activity.…”

Nitrification in fixed-bed reactors treating saline wastewater

“…In attached bacterial growth systems, nitrogen removal in the presence of high salinity has also been investigated , Rosa et al1998, Gharsallah et al 2002, Windey et al 2005. Attached growth on surfaces of support materials has many advantages as compared to suspended growth in flocs or granules, for instance a long sludge retention time, prevention of washout of biomass and better process tability in terms of withstanding shock loadings or short-term inhibitory effects (Fitch et al 1998, Nogueira et al 1998).…”
