MBT waste processing leachate a waste of money

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 […]

The 3 Most Important Leachate Indicator Parameters

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 […]

How a Membrane Bioreactor is Used to Treat Landfill Leachate

In principle, a membrane bioreactor combines biological treatment with a separation process using microfiltration membranes. A Membrane Bioreactor consists of a reactor tank and a microfiltration unit. In the reactor, the micro-organisms (mostly bacteria) transform dissolved polluted matter into biomass, and ammoniacal nitrogen (“ammonia”) into nitrate. Thus biodegradable organic pollutants are eliminated by the bioreactor […]

High Strength Leachate

When people refer to high strength leachate they are normally referring to the landfill leachate from a sanitary landfill which has percolated slowly through the waste. That is leachate and has been extracted by the leachate collection and pumping system. Usually high strength leachate has ammoniacal nitrogen concentrations above 500 mg/l up to 3.500 mg/l, […]

Landfill Leachate Composition

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 Waste Management Paper 26 contains the most recent table of Landfill Leachate Composition before the WMP series was superseded by later documents, notably the DoE’s Leachate Report of 1995.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, […]

Exactly What Is a Leachate Attenuation Zone?

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 […]

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 […]
