What is the Drainable Porosity of a Landfill?

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 […]

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 pumps and pumping technologies currently in use in landfills in the UK, and worldwide, are listed and explained.

Leachate Recirculation

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.
