How to Treat Landfill Leachate Using a Saltworks Crystallizer System
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 Crystallizer, for something completely new!
Leachate Quality from Landfilled MBT Waste and Why MBT is an Unjustified Waste of Money
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 […]
Construction Starts on the World’s Most Expensive Leachate Treatment Plant
Construction has started on the world’s most expensive leachate treatment plant which at $27 million will be the most expensive ever built in the world to date. A number of plants are estimated to have been built at up to $15 million previously, but this one is significantly the most expensive in terms of the […]
Is Long-Term Recirculation Of Leachate Concentrate From Reverse Osmosis Treatment Sustainable?
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.
The Principle of Reverse Osmosis Applied to Leachate Treatment
When leachate must be treated to a very high standard for watercourse discharges which require not only for the reactive components of leachate to be removed but also require non-reactive compounds to be removed such as the sodium chloride, which is always elevated in MSW landfill leachate, the technology of Reverse Osmosis may be the […]
Sanitary Landfill Leachate Past and Future
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 a significant possible environmental problem to be conquered. Although research and experience continue to […]
Leachate Recirculation Practise and Views
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 […]
Air Ammonia Stripping
Air Ammonia Stripping is a leachate treatment process which is now largely outdated and seldom used. During the 1980s in the United Kingdom it was seen as a potential physico-chemical leachate treatment process which would be suitable for the treatment of leachate from sanitary (lined and capped) landfills, however, although a number of pilot scale […]
How Do You Treat Leachate?
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 of Landfill Leachate for Energy Generation: Pipe-Dream or an Opportunity?
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 […]
