  • 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 ...

  • 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 ...

  • Leachates: Technologies for onsite sustainable leachate management

    Municipal landfill leachate is characterized by high concentrations of recalcitrant organic compounds, ammonia, suspended material and heavy metals. As a result, leachate is difficult to manage because conventional forms of biological and chemical treatment are inefficient at dealing with such a diverse and complex waste stream. Because of widely varying practices in solid waste management, an ...

  • 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 ...

  • Leachate Level Monitoring at Ardley

    B&M Solutions for Viridor Waste, July 2007 Supply of leachate level telemetry system for Ardley Landfill, Oxfordshire Hydro-Logic working alongside B&M Solution (Egniol Ltd) supplied and installed a monitoring network around Ardley Landfill Site. The network was to monitor the leachate levels in 15 wells around the full extent of the site. The ...

  • Membrane fouling in the nanofiltration of landfill leachate and its impact on trace contaminant removal

    Nanofiltration (NF) is an attractive option for the treatment of landfill leachate. However, membrane fouling can be a major obstacle in the implementation of this technology. In this study, bench-scale filtration experiments were carried out to study the fouling behaviour during the NF of a synthetic landfill leachate. The results indicate that calcium in combination with organic matter could ...

  • 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 ...

  • Inox in a landfill

    For collection and transport of leachate, landfill sites are using various types of pumps. Grindex electrical corrosion resistant pumps provide the volume needed where pneumatic pumps and other submersibles pumps fall short. One of the landfills in Illinois has 18 Grindex corrosion resistant pumps in operation and they now have plans to replace all remaining submersibles with Grindex INOX pumps. ...

  • Enso International Ltd select Biomarble from Warden Biomedia Range for Landfill Leachate reatment Plant at Nantycaws - Case Study

    The existing landfill leachate treatment plant at Nantycaws was failing to meet the consent levels, and Carmarthenshire County Council was tankering on a daily basis. The Council was therefore looking for a robust treatment solution that would meet the EA consent requirements and reduce the frequency of tankering. Working in collaboration with WEBS, EnSo International Ltd was called in to offer ...

  • Behaviour of Bulk and Trace Organics in a Full Scale Membrane Bioreactor for Landfill Leachate Treatment

    ABSTRACTLandfill leachates are generally highly pollutant wastewaters which have percolated through a deposit of solid waste. In many states it is now required to collect and treat landfill leachates to avoid contamination of surface and groundwater bodies. A state of the art technology for landfill leachate treatment uses membrane bioreactor technology prior to potential polishing with dense ...

  • 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 ...

  • 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 ...

  • Southwest landfill case study

    The Problem: A landfill located in Texas was experiencing high concentrations of ammonia in the leachate from their domestic landfill. Compliance standards were becoming more stringent at the same time ammonia and BOD levels in the leachate stream were increasing in concentration. The Solution: After on‐site testing ...

  • 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 ...

  • Ocean bacteria: performance on CODCr and NH4+-N removal in landfill leachate treatment

    An experiment was carried out to investigate the performance of mixed ocean bacteria, isolated from the ocean sediment, on landfill leachate treatment. In this treatment, ocean bacteria were the only constituent added to remove organics and NH4+-N. Given their considerable influence on wastewater purification, factors such as inoculum, initial pH, ...
