Advanced Oxidation Processes (AOPs) for reduction of organic pollutants in landfill leachate: a review
Uncontrolled municipal landfill leachate during landfilling can seriously pollute groundwater, surface water and soil. Over the past decades, a variety of Advanced Oxidation Processes (AOPs), primarily utilising hydroxyl radicals to effect water purification, have been frequently investigated for treatment of landfill leachate. This paper first summarises the typical characteristics of organic ...

The removal of ammonia from sanitary landfill leachate using a series of shallow waste stabilization ponds
This study evaluated the efficiency of a shallow (0.5 m deep) waste stabilization pond series to remove high concentrations of ammonia from sanitary landfill leachate. The pond system was located at EXTRABES, Campina Grande, Paraiba, Northeast Brazil. The pond series was fed with sanitary landfill leachate transported by road tanker to the experimental site from the sanitary landfill of the City ...

Photochemical Transformation of Bisphenol A Promoted by Nitrate Ions
Bisphenol A [2, 2-bis (4-dihydroxydiphenyl) propane] (BPA is widely used as a raw material for polycarbonate and epoxy resins. The residue level of BPA in surface water was shown to be at a rather high level, ranging from 4.4x10-10 to 5.3x10-8 mol L-1 by the U.S. Geologial Survey (Kolpin et al. 2002) and 5.7x10-9 to 5.7x10-5 mol L -1 in landfill leachates in Japan (Yamamoto et al. ...

Application of gas chromatography-mass spectrometry preceded by solvent extraction to determine volatile fatty acids in wastewater of municipal, animal farm and landfill origin
This study describes extraction of selected volatile fatty acids (VFAs) (containing from 2 up to 8 carbon atoms) with methyl-tert-butyl ether (MTBE) from polluted aqueous samples followed by separation, identification and quantification by gas chromatography coupled with mass spectrometry (GC-MS). Extraction parameters such as time and number of extractions, volume ratio, effect of acidification ...

How is Landfill Leachate Water Treated?
Current Issues - Landfill Solid Waste Pollution & Leachate The consistent increase of global human population coupled with changing lifestyles have lead to vast amounts of solid waste pollution, which causes resources depletion with a seriously negative environmental impact. Even though many methods have been utilized to overcome this solid waste pollution problem issue such as recycling ...

VSEP helps landills to meet strict discharge guidelines by removing suspended solids and dissolved organics and inorganics from landfill leachate
One of the most important problems with designing and maintaining a landfill is managing the leachate that is generated when water passes through the waste. The leachate consists of many different organic and inorganic compounds that may be either dissolved or suspended. Regardless of the nature of the compounds, they pose a potential pollution problem for local ground and surface waters. Many ...

Treatment of leachate using the DMT MemBioRex® technology
One of the most difficult waste waters to treat is leachate from a landfill. Leachate is water from the degrading waste and rainfall which percolates through the waste. Leachate usually contains a high concentration of ammonium, low concentrations of phosphor, high salinity, high alkalinity and various concentrations of heavy metals. Combined with strongly fluctuating flows, a high pH and ever ...

Landfill disposal of unused medicines reduces surface water releases
The pharmaceutical industry is conducting research to evaluate the pathways and fate of active pharmaceutical ingredients from the consumer to surface waters. One potential pathway identified by the researchers is the disposal of unused pharmaceutical products that are discarded by consumers in household trash and disposed of in municipal solid waste landfills. This study was designed to evaluate ...

Monitoring leachate composition at a municipal landfill site in New Delhi, India
Most of the landfills in developing countries do not have any liner at the base, or a drainage layer or a proper top cover, which results in the potential problem of groundwater/surface water contamination due to the leachate. Hence, to decide whether the leachate is to be collected and treated, or may be allowed to discharge into the adjoining soil or public sewer or surface waterbody, it is ...

What is the purpose of a liner in a landfill?
Because the garbage in the landfill is piled outside for a long time, it is easy to breed mosquitoes and flies, spread germs, and produce odor. Garbage is piled outside for a long time. Due to rain and other factors, there is running water. The garbage is wet and decomposes sewage leachate. The sewage causes pollution and great harm to the surrounding environment and residents. The main ...

Landfill site characterisation at Kham Bon village, Muang district, Khon Kaen province, NE Thailand
The aim of the study is to characterise the Kham Bon landfill site. Hydrogeological and geochemical surveys were conducted and four boreholes were drilled. The hydraulic properties of the aquifer were tested, and soil, surface water and groundwater samples were collected at various times in the year. The physical and chemical properties of the samples, especially heavy metals, were analysed. The ...

10 Common Questions When Choosing Earth Shield Geomembrane
1. What are the main reasons for using Earth Shield geomembrane in landfills? An important issue in landfills is the pollution control of leachate. After the landfill starts, a large amount of sewage is generated due to the influx of rainwater and surface water and the decomposition of the garbage itself. This is what we call leachate. This liquid has a high content of pollutants and a complex ...

Besides Polyethylene Geomembrane, What is the Anti-seepage Material of the Landfill?
With the rapid development of my country’s social economy and the acceleration of the process of urbanization and industrialization, the resulting air pollution, solid waste pollution, and the generation of large amounts of domestic garbage have brought tremendous pressure to environmental protection. Especially with the continuous expansion of major cities, the urban population has ...

Which Material is Best as A Liner for A Landfill
Landfill leakage pollution is very harmful to the environment. After the soil is polluted, it will be salinized, poisoned, parasites, pathogenic bacteria and other pathogens in the soil can make people sick. Infiltration can also contaminate groundwater and enter the human food chain, causing serious harm to the human body. Artificial material impermeability: geomembrane are usually high-density ...

How 3D Composite Drainage Net is Used in Landfill Projects?
A composite 3D drainage net (also known as a three-dimensional geotechnical drainage board, tunnel drainage board, or drainage board) is composed of a three-dimensional plastic mesh with double-sided bonding water seepage geotextiles, which can replace the traditional sand and gravel layers. The mesh double-sided bonding water seepage geotextile makes up a drainage tool, which is used for the ...
