  • 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 ...

  • How can lead be so crucial, but also so toxic?

    Why is everyone talking about lead? Not long ago, like so many historic buildings in the UK, a local parish church near to where I live had the lead stolen from its roof.  Sadly, this is not so unusual and all the more distressing in this case, both because it holds special memories as the church where my wife and I were married, and also because the lead was stolen during heavy ...

  • New LFG Collection System Utilizes QED’s Revolutionary LFG Measurement and Control Technology - Case Study

    “The main advantage, to me, is the Fine Tune™ Control Valve* that is used on the QED wellhead - it’s one of those revolutionary things in the landfill gas industry. Gate valves don’t give you very good control unless you always want the valve 100% open and you can apply as much vacuum as possible. But when it comes to low-flow wells then it’s important to be able to ...

  • South Texas Landfill − Case Study

    During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill. The following graphs show the composition of the landfill gas and flow data before and after the installation of the Control Valves in Wells 07, 54, 78, and 90. The closest neighboring well on the same trunk line, using a gate valve for flow control, was also chosen for an additional ...

  • Improved well tuning achieved at a Landfill gas to Energy developer`s sites - Case Study

    Building and managing a high-BTU landfill gas to energy system can present many challenges, but it’s not as complicated as it might seem. The key: start with a healthy, consistently productive wellfield. Morrow Renewables, formerly South Tex Renewables, specializes in doing just that. Headquartered in Midland, Texas, they began in the natural gas industry before building a reputation as one ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Landfills have a huge greenhouse gas problem. Here’s what we can do about it.

    We take out our trash and feel lighter and cleaner. But at the landfill, the food and yard waste that trash contains is decomposing and releasing methane, a greenhouse gas that’s 28 times more potent than carbon dioxide. Landfill gas also contributes to smog, worsening health problems like asthma. Globally, trash released nearly 800 million metric tons (882 million tons) of ...

  • Case study - Geotech’s first GA5000 landfill gas analyser takes 100,000 readings for SUEZ environnement

    Geotech’s first GA5000 analyser, manufactured three years ago, was recently spotted in the company’s calibration rig.  This portable landfill gas monitor was the first production unit of the newly launched GA5000 gas analyser range and has prompted Geotech to look into the analyser’s life since then. The analyser was on its sixth service since manufacture, under ...

  • 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 ...

  • The landfill gas collection, utilisation and surplus gas combustion acting in unison

    In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Assessing the Impacts of the Iran Nuclear Deal on Climate Change

    Introduction On July 14, 2015, the international economic boycott levied against Iran was scheduled to conclude. In concert with the European Union and the P5+1, the Islamic Republic agreed to a Joint Comprehensive Plan of Action (JCPOA) whereby its capacity for nuclear development would be dramatically curtailed.

  • 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 ...
