“…The anoxic/aerobic treatment reduces COD and NH 4 -N, while nitrogen removal is achieved in the subsequent UASB via Anammox. Under concentrations of influent ammonia and COD which were respectively 1330 mg/L and 2250 mg/L, the removal efficiencies of TN and COD reached 94% and 62% respectively [37]. Another study included partial nitrification using a sequencing batch reactor (PN-SBR) followed by a Anammox hybrid reactor (HAR), which consists of a suspended biomass layer in the bottom part and a bio-carrier bed in the upper part, run at the influent total ammonia concentrations (TAN) of 500 mg N/L and 1000 mg N/L.…”

“…Despite higher removal efficiencies achieved with aluminum, iron is considered the best electrode because it is less toxic, requires less energy, and is less sensitive to inhibitor phenomena [37]. Also, the distance between the electrodes could affect the efficiency of the removal of pollutants present in the leachate.…”

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.

BACKGROUND Simultaneous anammox and denitrification (SAD) can remove carbon and nitrogen. However, its performance is suppressed under saline surroundings. In this work, mannitol was used to enhance a SAD process treating saline wastewater. RESULTS The optimum carbon and nitrogen removal was achieved at 0.2 mmol L−1 mannitol, during which ammonium removal efficiency (ARE), nitrite removal efficiency (NRE) and chemical oxygen demand (COD) removal efficiency were 96.95%, 93.70% and 90.05%, respectively. The maximum ammonium removal rate (ARR), nitrite removal rate (NRR) and the specific anammox activity (SAA) were increased by 25.49%, 55.84% and 33.83% with optimum addition (0.2 mmol L−1 mannitol) respectively. The diameter of sludge was enlarged with the addition of mannitol (≤0.2 mmol L−1). The Tseng‐Wayman model was more suitable to simulate the whole SAD process. The modified logistic model, the modified Boltzman model and the modified Gompertz model were all appropriate to describe nitrogen removal in a typical cycle with the addition of mannitol. CONCLUSION Mannitol was effective in enhancing a SAD process treating saline wastewater, and maximum nitrogen removal was achieved at mannitol = 0.2 mmol L−1. The Tseng‐Wayman model satisfactorily predicted the whole SAD process treating saline wastewater with mannitol addition. © 2018 Society of Chemical Industry

“…Nitrogen removal from wastewater containing high concentrations of ammonium, such as industrial wastewater [1,2], landfill leachate [3,4], and the supernatant of a digester [4], using the anammox process has increased rapidly since its discovery. This process consists of two steps, each conducted by specific bacteria.…”

A new one-stage nitritation/anaerobic ammonium oxidation (anammox) process with two-inflow was proposed to provide suitable coexistence conditions for ammonium oxidation bacteria (AOB) and anammox bacteria. Reactor performances were examined using a two-inflow biofilm reactor fed with artificial ammonia-containing wastewater. For start-up, an anammox biofilm was cultivated in a wound filter set in the center of the reactor until the anammox process occurred stoichiometrically. Then, sponge media containing abundant AOB were added to the reactor, and aeration of the reactor began, also nitrite concentrations in the substrate decreased and the ammonium concentration increased gradually. Both anammox and nitritation occurred in the reactor. The maximum nitrogen removal efficiency achieved was 49%, the maximum ammonium conversion efficiency was 60%, and the maximum nitrogen removal rate was 0.228 kg-N/(m 3 ·d) at the nitrogen loading rate of 0.5 kg-N/ (m 3 ·d). It was estimated that ammonium oxidation (nitritation) occurred in the sponge; hence, the anammox reaction occurred in the biofilm attached to the filter.
