Ecotoxicological study of landfill leachate treated in the ANAMMOX process

Abstract

The exacerbated production of solid residues represents a major problem in the management and handling of urban wastes. The by-product of stored municipal and industrial solid waste production is landfill leachate. Leachate is characterized by a high concentration of organic compounds, ammonia, and the presence of heavy metals. Because of its composition, this kind of wastewater can cause serious environmental pollution and should be treated to reduce its toxic effects. Increasingly, the interest is directed to the application of the ANAMMOX (anaerobic ammonium oxidation) process for the landfill leachate treatment. In this study, for the first time, the effect of treatment with the ANAMMOX process on the toxicity of leachate was investigated. Based on the research performed in this study, it could be stated that the untreated landfill leachate from the municipal landfill and the influent of the ANAMMOX reactor present phytotoxicity to Lemna minor, due to a correlation of high concentrations of organic compounds, heavy metals, such as Cd 2þ , Cu 2þ , Zn 2þ , and the presence of an unionized form of ammonia (NH 3 ). The results of the Allium cepa test demonstrated that the treatment was not efficient in eliminating the genotoxic substances that are responsible for the mutagenic potential in the effluent.

Tetracycline Removal from Water by Adsorption on Geomaterial, Activated Carbon and Clay Adsorbents

“…The pH effect was investigated; 100 mg • dm -3 of tetracycline solutions were prepared in the pH range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). After adjustment, the solutions were mixed with 0.3 g of adsorbent during 24 h at 298 K. The pH was adjusted by using 0.1 N of HCl or KOH according to the desired pH value.…”

“…Therefore, the composition of leachates is very difficult to determine. Despite the complexity of the effluent, it is 1 Scientific and Technical Research Center in Physico-Chemical Analysis, PO box 384, Headquarters ex-Pasna Industrial area Bou-Ismail, zip code 42004 Tipaza, Algeria, phone +213(0)24325774, fax +213(0)24325774, ORCID: 0000-0002-1432-7237 2 LPCEMAE Laboratory, Faculty of Chemistry, Houari Boumediene University of Science and Technology (USTHB), PO box 32 ELALIA, Bab Ezzouar Algiers, Algeria, email: bhamdi_99@yahoo.fr, ORCID: 0000-0002-5502-1605 3 Controlled Porosity Materials Team, Institute of Materials Sciences of Mulhouse UMRCNRS 7361, University of Strasbourg, University of Haute Alsace, ENSCMu, 3 rue Alfred Werner, 68093 Mulhouse Cedex, France, email: jocelyne.brendle@uha.fr, ORCID: 0000-0001-5266-6224 possible to identify these xenobiotic compounds [9][10][11][12][13][14][15][16]: phenols, chlorinated aliphatic compounds, aromatic hydrocarbons, tetracycline, pesticides, and plasticizers.…”

Sustainable approach of biological treatment of landfill leachate by Anaerobic Ammonium Oxidation: A review

“…This transformation occurs in the presence of carbon dioxide (CO2), which serves as the carbon source necessary for the development of the Anammox bacteria (see Eq. 1) [22]. NH4 + + 1.3H + + 1.32NO2 -+ 0.06HCO3 -→ 1.02N + 0.26NO3 -+ 2.03H2O + 0.06CH2O0.5N0.15 (1) [23] It has been suggested that to optimize the use of scarce resources, it is possible to implement procedures that facilitate the recovery and recycling of nutrients found in sewage, so minimizing any potential harm to the environment.…”

State of the Art in Anaerobic Treatment of Landfill Leachate: A Review on Integrated System, Additive Substances, and Machine Learning Application

“…Annamox is particularly suited for the treatment of nitrogen-rich wastewaters, such as LFL. Anammox bacteria, converts ammonium into dinitrogen gas as depicted in Figure 6 by using ammonium nitrogen as an electron donor and nitrite as an electron acceptor under anoxic conditions [79]. It was demonstrated that treatment based on Anammox is promising for potential application in the elimination of nitrogen from LFL due to its cost-effectiveness (less aeration energy) and the high performance of denitrification [80].…”
