Leachate Recirculation Practise and Views
To the site operator leachate recirculation would certainly appear like commonsense as some of the leachate recirculated will be taken in by the waste and not re-appear. The leachate will gain some treatment – especially a significant reduction in BOD and COD by anaerobic digestion within a methanogenic landfill. In addition, if leachate is being […]
Landfill Leachate Composition
Landfill leachate composition for United Kingdom Landfills was first published in the Waste Management Papers published by the UK Department of Environment. Waste Management Paper 26 contains the most recent table of Landfill Leachate Composition before the WMP series was superseded by later documents, notably the DoE’s Leachate Report of 1995. However, the original table, […]
How you can Select the Best Pipework Material for Leachate Collection Systems in Three Simple Steps
This article is to make it easy to have success in selecting the best pipework material for leachate collection systems.
How Contaminants Leach Out of Landfill Waste and Into Leachate
A major problem arising from landfills is the discharge of leachate which is formed by water passing through the tip and thus becoming contaminated with various organic and inorganic pollutants. The subsequent movement of the leachate into the surrounding soil, ground water or surface water could lead to severe pollution problems. The mechanisms by which […]
Wastewater Treatment in Wetlands: Contaminant Removal Processes
An Introduction to Wastewater Treatment in Wetlands Originally published by U.S. Department of Agriculture, Cooperative Extension Service, University of Florida Wastewater treatment in wetlands can be highly effective, [including for leachates]. Wetlands are commonly known as biological filters, providing protection for water resources such as lakes, estuaries and ground water. Although wetlands have always served this purpose, […]
Leachate Landfills
Leachate landfills – general information about leachate, and how it is present in landfilled waste, affects landfills, and is collected.
Leachate
Leachate starts as rainfall. Rain falling on the top of the landfill is the main contributor to the generation of leachate, and is by far the largest contributor for modern sanitary landfills which do not accept liquid waste. In old unlined and un-engineered landfills, some leachate is produced from groundwater entering the waste. Some, additional […]
