Landfill Gas Monitoring Articles

Municipal solid waste landfill is site for domestic day-to-day waste disposal. Its also known as tip, rubbish dump, dumping ground, etc. Material stored at solid waste landfill is isolated from the environment by sealing layer which can be HDPE or LDPE or even PVC geomembrane. If such geomembrane leaks, the contaminant from landfill is spreading in direction of the groundwater flow. ...

PVC geomembrane liner is a kind of impermeable liner, which is widely used in the modern municipal solid waste containment system. PVC is an abbreviation for Poly Vinyl Chloride. They are installed in the side and bottom liners to inhibit flow of leachates and thus prevent the contamination of groundwater. Manufactured by the calendaring or extrusion process, BPM PVC geomembrane has high puncture ...

According to the Landfill Regulation and Federal Emission Law in Germany it is mandatory on landfills to monitor weather data such as temperature, precipitation, evaporation, wind direction and speed. This is not only good for environmental protection purposes but also for the residents nearby. In this regard two new Lufft weather stations and one Lufft wind sensor were set up recently in Hamberg ...

“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 ...

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 ...

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 ...

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 ...

Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...
