  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Treatment of landfill leachate by hybrid precipitation/microfiltration/nanofiltration process

    This paper describes a promising method to treat stabilized landfill leachate. Such method consists of a combination of chemical precipitation processes, a cost-effective technique with high potential to remove contaminants with foulant nature, microfiltration aimed at removing the produced precipitate and nanofiltration (NF) for final polishing. This study was carried out on a bench unit ...
