Is Long-Term Recirculation Of Leachate Concentrate From Reverse Osmosis Treatment Sustainable?

leachater — Sat, 06 Apr 2013 21:30:52 +0000

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

leachater — Sat, 06 Apr 2013 01:04:47 +0000

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 [...]

How a Membrane Bioreactor is Used to Treat Landfill Leachate

leachater — Mon, 11 Feb 2013 00:01:34 +0000

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 [...]

Sanitary Landfill Leachate Past and Future

leachater — Sun, 21 Oct 2012 00:34:25 +0000

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 the significant possible environmental problem to be conquered. Although research and experience continue to [...]

Leachate Recirculation Practise and Views

leachater — Sat, 20 Oct 2012 22:06:18 +0000

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 [...]

High Strength Leachate

leachater — Sat, 20 Oct 2012 20:14:20 +0000

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, [...]

Air Ammonia Stripping

leachater — Sat, 20 Oct 2012 19:49:02 +0000

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

leachater — Sat, 20 Oct 2012 15:01:10 +0000

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, [...]

What are the Strategies for Landfill and Leachate Management?

leachater — Tue, 16 Oct 2012 00:47:47 +0000

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 [...]

How Do You Treat Leachate?

leachater — Mon, 15 Oct 2012 14:12:08 +0000

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 [...]
