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!

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 […]

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 […]

leachate indicator parameters

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 […]

reverse osmosis recirculation

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 […]

membrane bioreactor

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 […]

leachate recirculation in a landfill

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 […]

Landfill leachate composition - image for page

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, […]
