  • 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 ...

  • 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 ...

  • pH and redox buffering systems of landfill leachate contaminated aquifer materials

    Introduction of landfill leachate into an aerobic aquifer leads to a variety of redox and pH buffering reactions between dissolved chemical species and aquifer sediments, which play profound effects on the behaviours of contaminants beneath and down gradient from the landfill. The specific objective of this study was to determine the spatial and temporal variations of pH and redox buffering ...

  • The effect of urban landfill leachate characteristics on the coexistence of anammox bacteria and heterotrophic denitrifiers

    Heterotrophic denitrification coexists with the anammox process contributing to N removal owing to the biodegradable organic matter supply from urban landfill leachate and the decay of microorganisms. Both biomasses consumed nitrite increasing the nitrite requirements of the system. The aim of this paper is the study of the causes which induce the system to decrease nitrogen removal efficiency. ...

  • Field Demonstration of a Permeable Bioreactive Barrier for Leachate Control.

    ABSTRACT: A biostimulation technique was selected for a pilot study to treat groundwater at a former New Jersey municipal landfill. The process will address a mixture of chlorinated compounds (e.g. vinyl chloride and chlorobenzene), hydrocarbons (e.g. benzene and methyl ethyl ketone) and heavy metals. The reactive barrier will be constructed using a series of injection points to implace a slurry ...

  • Landfill Leachate Treatment by Forced Circulation Vacuum Evaporation - Athens (Ano Liossia Landfill)

    This report describes how treatment of landfill leachate by means of forced circulation vacuum evaporation provided: an environmental benefit from use of biogas as power supply a big saving in disposal cost due to waste volume reduction a return on investment of less than two years Introduction Solid Waste Management in Greece has been remarkably upgraded during the last ...

  • Long-term leachate emissions from municipal solid waste landfills sre unknown

    The Swiss have always been highly environmentally aware, and for a long while have looked after their environment in an exemplary fashion. The 'Guidelines to waste management in Switzerland' ( EKA, 1986 ) were set in 1986, well ahead of many states. One necessary objective of this as a code of good practice has been that all waste management procedures have to provide materials which either are ...


  • Application of the central composite design for condition optimization for semi-aerobic landfill leachate treatment using electrochemical oxidation

    In the present study, Electrochemical Oxidation was used to remove COD and color from semi-aerobic landfill leachate collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. Experiments were conducted in a batch laboratory-scale system in the presence of NaCl as electrolyte and aluminum electrodes. Central composite design (CCD) under Response surface methodology (RSM) was applied to ...

  • Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water

    Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other ...

  • The BIOZO process – a biofilm system combined with ozonation: occurrence of xenobiotic organic micro-pollutants in and removal of polycyclic aromatic hydrocarbons and nitrogen from landfill leachate

    We present an assessment of xenobiotic organic micro-pollutants (XOM) occurrence and removal of polycyclic aromatic hydrocarbons (PAHs) in a novel biofilm system combined with ozonation, the BIOZO concept, treating partly stabilised landfill leachate. A novel, staged moving-bed biofilm reactor (SMBBR) design was implemented in laboratory- and pilot-scale, and the PAHs removal efficiency of ...

  • Treatment of leachate using the DMT MemBioRex® technology

    One of the most difficult waste waters to treat is leachate from a landfill. Leachate is water from the degrading waste and rainfall which percolates through the waste. Leachate usually contains a high concentration of ammonium, low concentrations of phosphor, high salinity, high alkalinity and various concentrations of heavy metals. Combined with strongly fluctuating flows, a high pH and ever ...

  • Use of vetiver grass constructed wetland for treatment of leachate

    Performance of Constructed Wetland planted with vetiver grasses for the treatment of leachate was investigated in controlled experiments involving horizontal subsurface flow constructed wetland (HSSFCW). The HSSFCW experimental unit had two cells, one planted with vetiver grasses and another bare. Both units were packed with limestone gravel as substrate and were operated with equal hydraulic ...

  • Membrane Bioreactor for Sanitary Landfill

    The Problem The county of Warren NJ owns and operates a sanitary landfill in Oxford Twp, NJ. The facility generates an average of 50,000 gallons per day of leachate, with peaks to 100,000 gallons per day. The facility was discharging to a local POTW from their lagoon, but they were facing requirements for nitrogen removal from the POTW and needed a new system to provide ...

  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • Major Considerations in Landfill Closure

    Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act (RCRA). Following closure, those same regulations ...
