Pumps and Impellers for Leachate Extraction and Leachate Pumping
Popular pump types used for leachate extraction and pumping systems is the submersible centrifugal (vortex) type pump, and in particular in the UK the FLYGHT pumps model range.
The Use of Willow Coppicing for Leachate Treatment
WRc, has reported on Willow Coppicing for Leachate Treatment field trials in Britain inquiring into the utilisation of short rotation coppice (SRC) willow to treat leachate. The method is in use at several UK landfills where it is reported to be a low cost sustainable method of leachate treatment.
Avoiding Over Reliance on the Hydrologic Evaluation of Landfill Performance (HELP) Computer Program
“The person who walks with his/her eyes on the stars, is susceptible to the puddles in the road.” We all would like to follow our stars, but at times we need to do some “puddle watching” too! Sometimes we need to know what not to do, what things and actions to avoid, and why…
What is the Drainable Porosity of a Landfill?
When designing any leachate management system, the assessment of the most economically viable 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 […]
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 […]
Leachate Pumps – Leachate Pumping Systems
Leachate pumps and pumping technologies currently in use in landfills in the UK, and worldwide, are listed and explained.
Leachate Treatment
The processes which have been consistently successfully applied, for muncipal waste landfill leachate from controlled landfills, are biological nitrification processes designed by specialist leachate process designers.
Landfill Leachate Collection and Extraction
Leachate extraction embraces landfill site wells and boreholes, pumping systems, plus pipelines, leachate monitoring and control systems.
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.
Leachate Management Techniques
Most landfills still generate leachate, and the first and most obvious action, when leachate starts to appear, is to… Read this to find out more!
