  • 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 ...

  • 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 ...

  • Leachate Monitoring Alarm System

    A Major Waste-Disposal Operator, Sept 2008 - ongoing Leachate Monitoring at Landfill Site near Reading Design and installation of a GSM-based telemetry system for monitoring leachate level and pumping rates at 5 no. boreholes. An ATEX certified intrinsically-safe depth pressure transmitter was selected due to the presence of explosive gases at the site. A ...

  • 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 treatment

    BOYDEL is pleased to confirm that we have produced great results running a heavily fuel and metals laced municipal landfill leachate through our LMR electrocoagulation reactor. The attached picture essentially speaks for itself except that the clear BOYDEL treated effluent is free of fuel smell and that the sludge depicted on the right side of the picture has not been further dewatered and is ...

  • 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 ...

  • 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 ...

  • Sequential treatment of an old-landfill leachate

    This work investigates the performance of combined techniques applied to the treatment of an old-landfill leachate, which presents high salinity, low biodegradability (BOD5/COD around 0.05) and high ammonia concentration. Three sequences of processes were employed, including coagulation/flocculation, chemical oxidation, biological treatment and ammonia stripping. The association of ...

  • Case Study, Colnbrook Leachate Plant.

    Triangle Ltd was contracted in 2008 by Biffa Waste Services at Colnbrook, Heathrow to resolve the problem of the landfill leachate borehole pumping system failing to deliver acceptable volumes to the SBR leachate plant. Initially they were achieving a maximum of 110m³/month during the fill/aerate treatment ...

  • Treatment of landfill leachate by effective microorganisms

    Five dominant strains, capable of treating leachate effectively, were isolated. The results showed that the removal efficiency of COD by using the mixed strains was higher than the pure strain, reaching 46.8%. The optimal inoculum concentration and the treatment time were 10.0% and 120 h respectively. The removal rate of COD reached the maximum at the temperature of 35°C and pH of 7.0. The ...

  • Leachate and Groundwater Quality in Lagos, Nigeria.

    ABSTRACT Water as a gift of nature is generally believed to have no enemy. Despite the abundance of fresh water on the earth, many regions are in deep crisis of water shortage due to there being polluted by human activities, or the ever increasing demand by industrialization and high population growth. Thus, groundwater is the alternative source of fresh water in areas where surface water is ...


  • What are the treatment options for landfill leachate?

    New contributor to Water/Waste Processing aims to answer readers’ most pressing questions It’s said the United States has 1,654 landfills, handling more than 250-million tons of trash each year. One Washington landfill covers a 2,545-acre area, has a 120-million-ton capacity and a 40-year expected trash-receiving life. The facility, the Republic ...

  • Fungi immobilization for landfill leachate treatment

    This paper investigated treatment of landfill leachate collected from Nonthaburi landfill site, Thailand, by using immobilized white rot fungi, namely, Trametes versicolor BCC 8725 and Flavodon flavus BCC 17421. Effects of pH and co-substrates were investigated at different contact times. Three types of co-substrates as carbon source used in this study are glucose, corn starch ...

  • Influence of magnetic treatment on the improvement of landfill leachate treatment

    Magnetic treatment is an alternative simple approach by which landfill leachate treatment could be improved. The purpose of landfill leachate treatment is to remove the Suspended Solids, Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD). Based on experiment by using circulation flowing system with a magnetic strength of 0.55 T, it was shown that the leachate quality could be ...

  • In Situ Physical/Chemical Treatment for Ground Water and Leachate

    The main advantage of in situ treatments is that they allow ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ processes, however, generally require longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Chemical and Biological Treatability Testing of an Industrial Leachate

    Remediation efforts are ongoing at the Avtex Fibers Superfund Site in Front Royal, Virginia. As part of the future remediation of several surface impoundments used for viscose waste disposal during plant operation, it may be necessary to extract contaminated leachate and groundwater for ex-situ treatment and discharge to the Shenandoah River. This waste stream contains high concentrations of ...

  • Effect of initial biomass on cellulose hydrolysis by leachate communities

    Batch anaerobic digestions were performed in 160 ml serum vials, cellulose (1% wt) was the sole added carbon source. All reactors were inoculated with a 10% (v/v) leachate inoculum. The concentration of micro-organisms in the leachate inoculums was increased using centrifugation to investigate the effect of initial biomass on hydrolysis performance. The hydrolysis rate constant for digestions ...
