  • Ecotoxicity Assessment of Landfill Leachates using a Battery of Bioassay and Toxicity Characterization of the Leachates

    Abstract : The western part of Teshima Island in the Seto Inland Sea (Japan) had been used as an illegal dumping ground for more than 10 years and the accumulated waste was estimated to be about 510.000 tons. There has been no systematic toxicity assessment conducted on this waste. In this study, a battery of bioassays was applied to the collected leachates. Toxicity of the leachates was ...

  • Landfill 1, 2 & 3 repair - Case study

    ERC was hired as the General Contractor to perform repairs at 3 landfills in Tennessee for Johns Manville. The project consisted of replacing the leachate sprinkler systems, the leachate collection piping and lift stations, installing new landfill toe drains and re-capping large portions of the landfill. All waste encountered during the operation was either reappropriated into the landfill or ...

  • Leachate Collection & Removal Systems – Pump Stations

    Romtec Utilities designs and supplies pump stations for many different types of applications, including leachate collection and removal systems. Leachate pump stations are required whenever water passes through a bed of solids and extracts contaminating elements. The most common scenario for collecting and pumping leachate is for landfills, but there are industrial applications as ...

  • Spatial and temporal variation of water quality of a segment of Marikina River using multivariate statistical methods

    Payatas landfill in Quezon City, Philippines, releases leachate to the Marikina River through a creek. Multivariate statistical techniques were applied to study temporal and spatial variations in water quality of a segment of the Marikina River. The data set included 12 physico-chemical parameters for five monitoring stations over a year. Cluster analysis grouped the monitoring stations into ...

  • Help Your Spoils Pass the Paint Filter Liquid Test

    One of the most important functions of a drilling fluid is to stabilize and maintain a borehole opening. Borehole stability in coarse soils starts with creating an impermeable barrier between the soil and the drilling fluid or slurry via the filter cake (or polymer gel membrane for non-rotary mud drilling such as foundation drilling). Then, positive hydrostatic pressure from having the hole full ...

  • AutoPumps Manage Landfill Leachate to Keep Methane Flowing - Case Study

    Green Bay adds Gas-to-Energy Facility to 30-year-old Landfil Brown County East Landfill in Green Bay, Wisconsin recently completed a feasibility study that determined it would be economically sound to convert methane gas into electrical energy by electric generators to the site. Two new Cat 3516A+ engines are projected to come on line in December of this year, housed in a new 30 x 100 foot ...

  • 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 ...

  • Watch your Language! Geosynthetics vs Traditional Materials

    During GeoAmericas 2016, Dr. Neil Dixon’s sustainability keynote touched upon many topics for the future of geosynthetics. While sustainability drove most of the lecture, a few of his ideas simply approached how the field positioned itself in the marketplace. He suggested, for example, moving the field away from isolating language like “versus traditional materials.” With 40+ ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Ontario Landfill Site - Case Study

    A Texas based company with waste management sites around North America have installed electrical generation plants at various locations that use methane collected from the waste. The daily operation of these sites include the management of the leachate, a liquid waste by-product of decomposition, and the collection of gas for electricity production. This is typically carried out at multiple wells ...
