“…Khattabi et al (2002) found a high electrical conductivity in leachate from Etueffont landfill, Belfort France, influenced mainly by chloride, bicarbonate and cations. High concentrations of chloride and sodium ions in the leachate can inhibit biological anaerobic treatment (Kawai et al, 2012). The analysis of the leachate from a landfill in Taiwan showed that the EC decreases with increasing age of the landfill (Fan et al, 2006).…”

Abstract:The disposal of Municipal Solid Waste (MSW) in sanitary landfills produces leachate, whose composition changes depending on the microbial community and the environmental conditions. However, these changes cannot be observed in sanitary landfill because of the superposition of cells, which makes it difficult to determinate the relationship among the phases of biodegradation of MSW, the composition of the leachate and the time required for complete stabilization of the waste. This illustrates the importance of building experimental cells that simulate landfill to monitor the leachate over a long period. This study aimed to analyze the composition of the leachate generated from an experimental cell built on the Delta A sanitary landfill of Campinas City, Brazil, over 945 days. The leachate showed a transition from an acidic anaerobic phase to a methanogenic phase within approximately 100 days. By the one-hundredth day, the leachate showed a characteristically low pH, between 5.0 and 6.0 and a high Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) such as a young leachate with high biodegradability. Moreover, there was an intense leaching of the metals Cd, Fe, Pb and Mn, with concentrations higher than those allowed for the release in water bodies, according to Brazilian law. After the one-hundredth day, the leachate was characterized as stabilized. The pH increased and the concentration of volatile fatty acid, COD and BOD decreased. Co, Zn, Ni and Cu were leached. The potentially toxic metal concentrations found in the leachate also were above the values allowed by Brazilian law.

In Tunisia, the anaerobic digestion process is regarded as a new alternative for the treatment of landfill leachate (LFL). Raw LFL contained high amounts of organic matter, high ammonia concentrations and low biodegradability. In order to improve anaerobic conditions and biogas yields, pretreatment using coagulation‐flocculation, Fenton oxidation (FO) and air stripping processes were investigated and compared in terms of biogas production. Air stripping process was optimized using Response Surface Methodology (RSM). Central Composite Design (CCD) was used with three factors. Under optimized conditions, removals of 85% ammonia, 26% chemical oxygen demand (COD) were achieved. Coagulation‐flocculation provided an increase in the effluent biodegradability with 46% of COD reduction. Fenton's oxidation allowed reducing 48% COD, 30% of biological oxygen demand (BOD5). The effect of pretreatments was investigated with the biochemical methane potential (BMP) assay. A comparison of three different pretreatment methods of LFL for biogas production was performed. Air stripping was demonstrated as providing a better biogas yield than other pretreatments which reached 588 mL/g CODint. The best methane yield was obtained using air stripping pretreatment under optimized conditions. It can result in more robust and effective anaerobic digestion. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1041–1049, 2018

“…With respect to above anaerobic processes, mediated by sequential fermentation reactions driven by microorganisms converting organic pollutants into simpler molecules (ultimately into CO 2 or CH 4 ) (Appels et al, 2008;Kawai et al, 2012), the properties of fresh leachate are considered as the critical role. The amount as well as constituent of organic substances in the leachate restricts the operation of bioreactors to a great extent.…”

“…Recently, several studies have been conducted to understand impacts of seasonal alterations (such as rainfall regime, physicochemical conditions at the dump) on the landfill leachate characteristics (Kawai et al, 2012;Rafizul and Alamgir, 2012;Tsarpali et al, 2012). However, there is hardly any effort dedicated to seasonal variations in the characteristics of the fresh leachate from RTSs, which possesses rather high strength compositions and is expected to be disposed by bio-processes first.…”
