Leachate Management
Biological vs. Chemical Leachate Treatment for Municipal Solid Waste Landfills: What Works Best
Landfill leachate is a complex wastewater requiring targeted treatment. Biological methods excel with biodegradable waste, while chemical processes handle heavy metals and recalcitrant organics. The best approach combines both to meet regulatory thresholds effectively, considering factors like leachate age and landfill stage for optimal results…
MBT Leachate Management: Treatment Options, Compliance & Operational Costs
MBT leachate presents unique challenges with high ammonia, metals, and PFAS, necessitating multi-stage treatments. Effective systems blend biological and advanced oxidation techniques. Design is key to controlling costs and ensuring compliance, with research highlighting the Methane Phase Bed reactor’s role in optimal treatment solutions…
Strategies for Minimising Leachate Generation in Landfills
Leachate — the contaminated liquid produced when water percolates through landfill waste — is one of the most significant environmental risks of solid waste disposal, so minimising leachate generation is vital. According to research published in Frontiers in Environmental Science, landfills’ leachate is a complex and hazardous liquid whose composition is influenced by landfill age, […]
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 […]
What are the Strategies for Landfill and Leachate Management?
There are two strategies for leachate management. The most common and indeed the only legal way to 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 the […]
Landfill Leachate Dilute and Disperse Philosophy and the Leachate Attenuation Zone
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 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 […]

Avoiding Over Reliance on the Hydrologic Evaluation of Landfill Performance (HELP) Computer Program
“The person who walks with his/her eyes on the stars, is susceptible to the puddles in the road.” We all would like to follow our stars, but at times we need to do some “puddle watching” too! Sometimes we need to know what not to do, what things and actions to avoid, and why…
What is the Drainable Porosity of a Landfill?
When designing any leachate management system, the assessment of the most economically viable method for leachate treatment and disposal is heavily dependent upon the flow rate and duration of flow. A high capital cost option, such as on-site leachate treatment, will be worthwhile, but only if the total volume the plant treats daily is sustained […]
