In a research project completed on behalf of the UK Environment Agency data was collected data and leachates were sampled from EU landfills that had received imports of MSOR (Mechanically Sorted Organic Refuse) and Mechanical Biological Treatment (MBT) wastes, several years ago. The results of the sampling exercise were analysed for, the presence of trace […]

The Reverse Osmosis process is unique, it alone consistently removes salts (salinity) from leachate, apart from prohibitively energy expensive, physical evaporative methods, so it is an obvious candidate for leachate treatment.
INTRODUCTION Within the last many years there have actually been major advances in the variety, engineering and control of landfill sites; however it is still a fact that at many sites the generation of very polluting sanitary landfill leachates is still the significant possible environmental problem to be conquered. Although research and experience continue to […]
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 […]
The Leachate Attenuation Zone Explained A leachate attenuation zone is essentially a buffer zone around a landfill that protects against contamination of groundwater by its pollution from dangerous or hazardous wastes. Lots of older landfills were developed before stricter laws were implemented have been described as having “leachate attenuation zones”. In the UK these types […]
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 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.
Leachate landfills – general information about leachate, and how it is present in landfilled waste, affects landfills, and is collected.
