  • 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 ...

The network was to monitor the leachate levels in 15 wells around the full extent of the site. The ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...


  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

  • Municipal landfill leachate treatment by SBBGR technology

    The paper reports the results of a laboratory-scale investigation aimed at evaluating the performance of a periodic biofilter with granular biomass (SBBGR) for treating leachate coming from a mature municipal landfill. The results show that the SBBGR was able to remove roughly 80% of COD in leachate. The remaining 20% of COD were, therefore, presumably owing to the presence in the leachate of ...

  • Preparation and Performance of Inorganic Coagulant for Landfill Leachate Pretreatment

    Landfill leachates are often defined as hazardous and heavy polluted wastewaters. It may contain large amount of organic matter, ammonia-nitrogen, heavy metals, chlorinated organics and inorganic salts (Wang et al. 2002). Proper treatment of leachate has therefore been a challenging problem confroting the local authorities. Anaerobic digestion or/and aerobic activated sludge methods are the most ...
