“…To maintain a stable operation of the anammox process, the free ammonia concentration should be less than 20 -25 mg/L, whereas nitrites can inhibit anammox in concentrations above 100 mg·L -1 , or less [3]. However, maximum NRR (1.023 kg N/m 3 d) and specific anammox activity (0.638 g N/g VSS·d) achieved in this work was in the range reported by other studies [11][12][13][14]. Similar research where SBR was fed with high nitrogen load synthetic wastewater, was described by Lopez et al [11].…”

Abstract. The anaerobic ammonium oxidation (anammox) process is one of the most energy efficient and environmentally-friendly bioprocess for the treatment of the wastewater with high nitrogen concentration. The aim of this work was to study the influence of the high nitrogen loading rate (NLR) on the nitrogen removal in the laboratory-scale anammox sequencing batch reactor (SBR), during the shift from the synthetic wastewater to landfill leachate. In both cases with the increase of NLR from 0.5 to 1.1 -1.2 kg N/m 3 d, the nitrogen removal rate (NRR) increases to about 1 kg N/m 3 d, but higher NLR caused substrates accumulation and affects anammox process efficiency. Maximum specific anammox activity was determined as 0.638 g N/g VSS·d (NRR 1.023 kg N/m 3 ·d) and 0.594 g N/g VSS·d (NRR 1.241 kg N/m 3 ·d) during synthetic and real wastewater treatment, respectively. Both values are similar and this is probably the nitrogen removal capacity of the used anammox biomass. This indicates, that landfill leachate did not influence the nitrogen removal capacity of the anammox process.

“…As this partial nitrification process is limited to nitrite rather than nitrate in the conventional process, 25% of the aeration energy is saved, 30% of the sludge is reduced, and overall 20% less CO 2 is emitted [20]. This method is usually operated in a continuous stirred tank reactor (CSTR) or swim-bed reactors (SBRs) without biomass retention, where aerated and non-aerated periods are alternated to reach nitrification and denitrification processes, respectively.…”

“…As a result, this allows combining removal processes: anaerobic and aerobic treatments are applied together for wastewater management mostly to remove organic substances and nitrogen-based compounds by nitrification and denitrification processes. Nitrification involves two steps-the oxidation of ammonia to nitrite by ammonium-oxidizing bacteria (AOB), followed by the oxidation of nitrite by nitrite-oxidizing bacteria (NOB), whereas denitrification involves denitrifying bacteria for the conversion of nitrate to nitrogen gas [20].…”

Novel and Conventional Technologies for Landfill Leachates Treatment: A Review

et al. 2016

View full text Add to dashboard Cite

Abstract:Municipal solid waste final disposal represents an environmental burden worldwide since landfilling, or open dumping, is still the preferred solution for the end of life of solid discarded materials. This study aims to review the technological innovations applied for landfill leachate treatment, taking into consideration the experiences obtained during the past years and the solutions which have been implemented. The review showed that both biological and physiochemical treatments are not able to achieve the requested water quality level, according to the limits established by regulations, whether applied in a single treatment or multiple treatments. In order to respect sustainable release limits to guarantee environmental protection, the construction of depuration systems and combining biological and physiochemical treatment methods is considered of the utmost importance. The review looks at possible joint applications of different treatment techniques reviewed by other studies and considers the state of the art of current research. Combined technical solutions suggested within the 2016 peer-reviewed papers are presented and discussed as a sustainable way to effectively treat landfill leachate, giving particular attention to feasible solutions for developing countries.

“…Partial nitritation systems were developed by the Delft University of Technology in 1996-1999 [11] and have several advantages over total nitritation-based technologies, such as 25% savings in aeration, 30% reduction of biomass generation, with a biomass yield of about 0.15 g biomass (g NH 4 + -N) −1 [12], and 20% less CO 2 emission [11]. Partial nitritation bioreactors at the laboratory scale have been reported to successfully treat food processing and agriculture industry wastewater, reject wastewater and slaughterhouse wastewater or swine manure wastewater, among others [13][14][15][16][17][18][19].…”

Nitrogen is a main contaminant of wastewater worldwide. Novel processes for nitrogen removal have been developed over the last several decades. One of these is the partial nitritation process. This process includes the oxidation of ammonium to nitrite without the generation of nitrate. The partial nitritation process has several advantages over traditional nitrification-denitrification processes for nitrogen removal from wastewaters. In addition, partial nitritation is required for anammox elimination of nitrogen from wastewater. Partial nitritation is affected by operational conditions and substances present in the influent, such as quinolone antibiotics. In this review, the impact that several operational conditions, such as temperature, pH, dissolved oxygen concentration, hydraulic retention time and solids retention time, have over the partial nitritation process is covered. The effect of quinolone antibiotics and other emerging contaminants are discussed. Finally, future perspectives for the partial nitritation process are commented upon.
