Drugs in Municipal Landfills and Landfill Leachates

2004
Drugs and drug metabolites are a new class of organic micropollutants which have been found in low concentrations (ng 1−1 to µg 1−1) in wastewater, ground and surface water (Hailing-Sorensen et al. 1997; Heberer 2002; Kummerer 2001; Sacher et al. 2002; Spengler et al. 2001). Recent monitoring studies indicate that in many cases the main route for human

Treatment of Landfill Leachate by Irrigation and Interaction with Landfill Gas

Environmental Technology, 2006
The treatment efficiency of landfill leachate irrigation and the effect of landfill gas addition were investigated in a vegetated compost/gravel substrate by monitoring soil moisture content, drainage water volume and quality in a two years lysimeter experiment.

Modelling flow to leachate wells in landfills

Waste Management, 2004
Vertical wells are frequently used as a means of controlling leachate levels in landfills. They are often the only available dewatering option for both old landfills without any basal leachate collection layer and for newer sites where the installed drainage infrastructure has failed.

Landfill Leachate Treatment

2020
One of the most important aspects that must be taken into consideration during the operation and management of landfills is their capacity to generate leachate and particular attention must be paid to the protection of surface and ground waters. Leachate is a complex organic liquid formed primarily by the percolation of precipitation water through the ...

Treatment and detoxification of a sanitary landfill leachate

Chemosphere, 2004
The leachate from an old sanitary landfill (Gramacho Metropolitan Landfill, Rio de Janeiro) was characterized and submitted to coagulation and flocculation treatment followed by ozonation and ammonia stripping. The performance of the treatment was assessed by monitoring the removal of organic matter (COD and TOC), ammonium nitrogen and metals ...

Bioassays for the Evaluation of Landfill Leachate Toxicity

Journal of Toxicology and Environmental Health, Part B, 2009
This article reviews the application of bioassays for assessing the toxicity hazard posed by landfill leachate discharged to an aquatic environment. Landfill leachate is a complex mixture of chemicals; thus it is difficult to assess the risk posed to aquatic wildlife using standard chemical identification techniques, such as gas chromatography-mass ...

Phytoremediation of Landfill Leachates

2017
Municipal landfill leachate is a complex refractory wastewater which consists of extensive level of organic compounds, ammonia, and heavy metals. Contamination of water by landfill leachate has become a serious environmental concern worldwide due to its adverse impact on human health, aquatic organisms, and agricultural crop production. In recent years,

Landfill leachate treatment in Brazil – An overview

Journal of Environmental Management, 2019
The management of municipal solid waste (MSW) presents an ever increasing and more complex challenge in global terms. The disposal of MSW in landfills generates leachate, a liquid highly polluting to the aquatic environment. This review describes the state-of-the-art approaches to treatments applied to leachate in Brazil, highlighting the new ...

Municipal Landfill Leachate

In developing countries, the environment and human health are adversely impacted by dumping site leachate. Hence, this review examined landfill characteristics, associated risks, challenges and solutions. Open landfills were commonly used methods surrounded by residents, without leachate management.

Polishing Of Landfill Leachate

2015
This chapter deals exhaustively with the various techniques employed in polishing landfill leachate, the role, importance and effects of polishing leachate and the use of constructed wetlands with many examples from some countries where it has worked with considerable success. Types, forms and functions of wetlands in leachate polishing were also dealt
