“…Nitrification accounts for 63% of ammonium removal but a significant part (37%) of the ammonium could not be accounted for by nitrification [39]. Other studies, also reported in previous reviews [15], introduced leachate treatment plants where a two-stage anaerobic/facultative lagoon system, with an anaerobic section characterized by a 32-day retention time and a 22.8 • C temperature and a facultative section characterized by 240-day retention time and a 14.3 • C temperature, achieved removal rates equal to COD 40%, BOD 64%, NH 4 -N 77%, NO 3 -N 63%, P 42%, Cl − 27%, SO 4 2− 44%, Fe 30% [22]. Despite that, this treatment is suggested in countries with extensive free areas, with no energy available and low economic funds.…”

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.

“…Most of the characteristics confirmed this assumption. As expected, the leachate was high in BOD 5 , COD, Sodium, Potassium sand a few heavy metals; especially Ni and Cr. Chromium comes into the leachate from paint products and wood preservatives that get added into the municipal solid waste and nickel is added from used batteries [1].…”

“…Rather, these are globally considered the best option for managing municipal solid waste [2,3] and have maintained their status of the eventual fortune for all types of solid waste [4]. Further, this is the cheapest way for the disposal of large amount of waste [5] and is hence a common practice in most of the countries across the globe [6].…”

Leachate is the water contained in the solid waste dumped in a landfill and comes out during its decomposition but continues to ooze out even after stabilization of the solid waste and many years after the closure of the landfill. It contains a number of toxic and hazardous compounds, and is likely to contaminate the environmental sinks. Moreover, this leachate varies in its flows and characteristics over different phases of a landfill life. Leachate management is one of the major concerns and tough task associated with the landfill operation, and comprises monitoring and predicting landfill leachate and the variation in its flows and composition, associated risk assessment and hazard rating, and designing the most accurate treatment system before disposing it into environmental sinks. This study has analyzed the characteristics of a newly designed landfill site on modern lines at Lakhodair, Lahore, finding it to be slightly alkaline and high in organic matter (BOD 5 , COD), Na, K and a few heavy metals (Ni and Cr) of the sixteen pollution indicators (EC, turbidity, hardness, TDS, TSS, BOD 5 , COD, Na, K, Cl, Ni, Cr, Pb, Mn, Cu, Zn), which indicates it can easily be treated with simple physic-chemical methods; such as coagulation/flocculation, sedimentation, filtration, and biological treatment, and brought into some reuse such as irrigation.

“…The estimation of quality of leachate generated is important for evaluating surface and ground water contamination and it is an indicator for the landfill degradation stage [11]. Biodegradable landfill produces leachate that contains significant ammonical nitrogen concentrations.…”

Leachate Characterization and Leachate Pollution Index from Landfill Dump Sites in Warri Metropolis, Nigeria

ABSTRACT. The paucity of standard engineered landfills in Nigeria has given rise to the proliferation of open waste dumpsites. The environment can be impacted by leachates from these dumpsites if not properly managed. This study assessed the characteristics of leachates from three open dumpsites in Warri Metropolis and its contamination potential using leachate pollution index (LPI). The dump sites had low pH with acidic level lower than the recommended limit. The calculated LPI values of the three sites ranges from 6.377 to 7.438. These values are low when compared to open dumpsites in other metropolitan areas of similar climatic conditions. The low value of LPI for leachate indicates relatively lower contaminant potential due to low concentrations of heavy metals, relatively young age of the landfill as well as low population and organic origin of the wastes. The calculated low LPI value does not in any way preclude the continuous monitoring of the dumpsites as the values recorded are just slightly below the threshold level. It is recommended that there should be an upgrade of all open dumpsites to a standard engineered landfill with a robust and effective monitoring put to curtail future release of deleterious materials from these dumpsites
