Treating landfill leachate by electrocoagulation
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2009The determination of the optimal conditions for using electrocoagulation as a treatment for landfill leachate was carried out using surface response methodology. A central composite design was applied to investigate the effect of four control factors, namely current density, pH, time and fluid conductivity, as well as the ...

Treatment of landfill leachates
Journal of Hazardous Materials, 1987Abstract Landfill leachate, which resembles concentrated mixed industrial waste water, threatens national groundwater supplies. Several processes drawn from industrial water treatment have been considered for renovating landfill leachate: biodegradation, chemical and thermal degradation, adsorption, reverse osmosis, and coagulation/precipitation ...

Drugs in Municipal Landfills and Landfill Leachates
2004Drugs 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

Membrane Technology, 2005
This feature looks at the use of membrane bioreactor technology for landfill leachate treatment. It also attempts to explain why landfill operators in the UK have not used the technology for leachate treatment.

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.

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 of Landfill Leachate by Irrigation and Interaction with Landfill Gas
Environmental Technology, 2006The 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.

Treatment and detoxification of a sanitary landfill leachate
Chemosphere, 2004The 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 ...

Landfill leachate treatment in Brazil – An overview
Journal of Environmental Management, 2019The 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 ...

Modelling flow to leachate wells in landfills
Waste Management, 2004Vertical 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.
