Air Ammonia Stripping is a leachate treatment process which is now largely outdated and seldom used.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 […]
Landfill leachate composition for United Kingdom Landfills was first published in the Waste Management Papers published by the UK Department of Environment. Waste Management Paper 26 contains the most recent table of Landfill Leachate Composition before the WMP series was superseded by later documents, notably the DoE’s Leachate Report of 1995. However, the original table, […]
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 […]
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 […]
Landfill Leachate Dilute and Disperse Philosophy Landfills in the UK, built before the mid 1980’s were typically designed on a principle of dilute and disperse (EA, 2001/ Brown Book). The location of such sites was chosen so that the attenuation capacity of the underlying strata was sufficient to remediate the impact of the waste mass. […]
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 […]
Download our FREE time saving calculator which is intended for use for trade effluent discharge cost assessments for England, Wales and Northern Ireland in respect of sewer discharges. The Free Trade Effluent Charges Calculator software will be useful for anyone making an industrial effluent discharge to a sewer, and who wants to know how much […]
In recent years there has been a trend toward MSW leachates from Sanitary Landfills throughout the world becoming more similar, however, as Mechanical Biological Treatment (MBT) is increasingly implemented and more Mechnanically Sorted Organic Residue (MSOR) [also known as “residual waste”] is produced in the supply area for a landfill, so the leachate quality of […]
This article is to make it easy to have success in selecting the best pipework material for leachate collection systems.
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.
