Glass Fused to Steel Tanks – Advantages and Disadvantages
Glass Fused to Steel Tanks (GFS) are popular for leachate treatment applications. However, they do have some negative characteristics. We thought it would be useful to discuss our view of GFS tanks. Read on to find out more! Introducing Glass Fused to Steel Tanks (GFS) CSTR biogas digester tank tanks are the most popular tank […]
Efficient Aerators Key to Leachate Treatment Plant Refurbishment at Yorwaste’s Harewood Whin Landfill
At a recent Leachate Treatment Plant Refurbishment efficient aerators were needed to both fully mix and aerate the whole lagoon. In fact, consistently good mixing and oxygen transfer are always at the core of any successful aeration lagoon design. That’s where aerator and pump specialist Landia’s equipment has been used, and we are pleased to reproduce […]
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 […]
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 […]
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 […]
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 […]
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 […]
