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 […]

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, […]
There are two strategies for leachate management. The most common and indeed the only legal way to do manage leachate in the European Union countries is to keep the waste as dry as possible, and not introduce any liquid wastes. That produces the least amount of leachate, and keeps costs low during the infilling of […]
This article is to make it easy to have success in selecting the best pipework material for leachate collection systems.
When designing any leachate management system the assessment of the most economic method for leachate treatment and disposal is heavily dependent upon the flow rate and duration of flow. A high capital cost option such as on site leachate treatment will be worthwhile, but only if the total volume the plant treats daily is sustained […]
Leachate extraction embraces landfill site wells and boreholes, pumping systems, plus pipelines, leachate monitoring and control systems.
Leachate recirculation in the form of pumping leachate from the base of a cell back up into the top of the waste has been practised in the past, and continues to be used, at the majority of landfills.
Leachate landfills – general information about leachate, and how it is present in landfilled waste, affects landfills, and is collected.
