When to Install Reed Beds or Biological SBR Treatment
“Making a good choice whether to Install Reed Beds or Biological SBR Treatment Processes for Treating Landfill Leachate” The question often arises for landfill operators, of whether to use a “SBR” Leachate Treatment Process, or if the cheaper alternative of a reed bed can be used. The answer is that it depends entirely on the strength […]
High Strength Leachate
When people refer to high strength leachate they are normally referring to the landfill leachate from a sanitary landfill which has percolated slowly through the waste. That is leachate and has been extracted by the leachate collection and pumping system. Usually high strength leachate has ammoniacal nitrogen concentrations above 500 mg/l up to 3.500 mg/l, […]
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 Waste Management Paper 26 contains the most recent table of Landfill Leachate Composition before the WMP series was superseded by later documents, notably the DoE’s Leachate Report of 1995.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 Do You Treat Leachate?
First of all when asked the question, “How Do You Treat Leachate?”, we would like to make a distinction between true treatment which involves converting environmentally damaging substances to less, or non-toxic, ones, and simply concentrating the contaminants from the water in leachate to give a volume reduction. In the water industry both are known as […]
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 […]
