  • Landfill leachate treatment

    Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent ...

  • Electrochemical treatment of landfill leachate

    Electrochemical methods can offer an elegant contribution towards environmental control as electrons provide a means of removing pollutants by redox reactions. In the process of electrochemical oxidation the main aim has been to convert oxidisable species into carbon dioxide. Leachate originating in landfills is complex wastewater that could exert high environmental impact. This study aims to ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...

  • Landfill leachate as a mirror of today's disposable society: Pharmaceuticals and other contaminants of emerging concern in final leachate from landfills in the conterminous United States

    Final leachates (leachate after storage or treatment processes) from 22 landfills in 12 states were analyzed for 190 pharmaceuticals and other contaminants of emerging concern (CECs), which were detected in every sample, with the number of CECs ranging from 1 to 58 (median = 22). In total, 101 different CECs were detected in leachate samples, including 43 prescription pharmaceuticals, 22 ...

  • Landfill Diebesstieg/Disposal Centre, Salzgitter-Diebesstieg, Germany: Landfill Leachate Ozone Treatment Plant

    Since June 1994, the Salzgitter-Diebesstieg landfill has been operated by the 'Disposal Centre Salzgitter GmbH' as a municipal waste landfill for the urban area of Salzgitter. The permit for this landfill stipulated that a plant be constructed for treating the accumulating leachate. Based on the water qual- ity requirements for direct discharge into a waterway, from Appendix 51 of the ...

  • Combined Landfill Gas and Leachate Extraction Systems

    There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a ...

  • Ultrafiltration and Reverse Osmosis for Landfill Leachate Treatment

    Lanchester Landfill serves Eastern Lancaster County and Western Chester County in PA for disposal of household and construction waste. The facility produces around 10,000 gals per day of leachate. The Problem The facility ran a single basin sequential batch reactor (SBR) and a filter press to dewater the solids for many years, but found that they first, could not sustain a ...

  • Hazard assessment of waste disposal sites. Part 2: a holistic approach for landfill leachates

    The review of literature and computer models described in Part 1 of this paper led the authors to conclude that a quantitative hazard assessment methodology does not exist, in holistic terms, for landfill leachate. Although there are various reports and models addressing different aspects of the methodology, they are not integrated and show different degrees of completion. This part of the paper ...

  • Landfill leachate treatment for biological nutrient removal from wastewater

    Substantial volumes of leachate have been generated at the recently opened lined cells of the Orange County Landfill located in central Florida. To accommodate these volumes, a force main was installed to deliver leachate to the Eastern Service Area Wastewater Treatment Facility (ESAWTF) operated by the Orange County Public Utilities Division, which uses a biological nutrient removal process. ...

  • Comparative analysis of extended aeration and Fenton process in landfill leachate treatment

    This research is undertaken to investigate various operating conditions for minimising sludge disposal and maximising chemical oxygen demand from leachate. With conventional extended aeration process the optimum removal of COD and colour were 36% and 24% respectively. In Fenton process, for optimum pH of 5 and optimum H2O2/Fe ...

  • Electrochemical oxidation of landfill leachates at pilot scale: evaluation of energy needs

    Two of the main drawbacks to be overcome before full scale implementation of boron-doped diamond electro-oxidation were addressed in this work; its energy consumption and hazard of formation of chlorinated organics. This was framed within a study in which the technical and economic feasibility of BDD electro-oxidation of landfill leachate was evaluated at pilot scale. On one hand, its technical ...

  • The landfill leachate evapotranspiration in soil?plant system with reed Phragmites australis

    Using of the reed – Phragmites australis – is an effective method of landfill leachate disposal. In presented two years' study the effectiveness of leachate evapotranspiration from systems with reed was investigated. Daily evapotranspiration was in the range from 1.01 mm/d to 3.15 mm/d in the first year of research and from 2.68 mm/d to 4.94 mm/d in the second year. The research showed that the ...

  • Ammonia recovery from landfill leachate using hydrophobic membrane contactors

    This article aims to evaluate membrane contactors capability to remove and recover ammonia from landfill leachate (LFL). A hydrophobic hollow fiber membrane module was used to achieve such purpose. A sulfuric acid diluted solution was used as extraction solution to speed up ammonia content removal. Several factors that have influence on ammonia removal and recovery capability such as ammonia ...

  • Tire Shredding: The Best Alternative

    From cars and trucks to planes, tractors, and forklifts, tires are used for a wide variety of vehicles. And those tires don’t last forever. Regardless of how many miles a tire travels, it should not be used longer than ten years past its manufacture date, as the rubber will grow brittle and can crack. This isn’t usually a problem, though, since most tires are replaced within three or ...
