Until now, the search for the perfect Leachate Treatment System has remained a dull one for those that know leachate. Somehow, all those contaminants it contains have contrived to make the most commonly used solutions highly complex, dependent on advanced technologies, and hard to operate successfully. Read about the new technology in the SaltMaker Evaporator […]

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 […]
There are three very important leachate indicator parameters which are used as indicators to identify leachate contamination in any water sample analysed in a water quality laboratory. These three parameters can give an initial guide to anyone investigating what appears to be pollution occurring in the vicinity of a landfill, as to whether the source […]
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.
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 […]
Anaerobic digestion is becoming increasingly popular in this age of high energy prices, and many more people are realising that whereas aerobic treatment systems consume large amounts of expensive energy, anaerobic digestion is a process which does the opposite. In fact it produces a net energy output. It is not surprising therefore, that many […]
This article is to make it easy to have success in selecting the best pipework material for leachate collection systems.
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 […]
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 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.
