An investigation of the surface and groundwater leachate from an old waste disposal site at Mamak, Ankara, Turkey
Mamak solid waste disposal site covers an area of approximately 0.5 square kilometre and the amount of waste it holds is around 13 × 106 m?. The amount of leachate measured through a weir at the toe of the body of waste is 164,000 m3? per annum. It is calculated that approximately 130,000 m? of this amount directly comes from the waste. Owing to the retention of precipitation by wastes, it takes ...

Electrocoagulation for Landfill Leachate Waste Water Treatment
Humans produce excessive amounts of waste. According to the EPA’s Advancing Sustainable Materials Management fact sheet, in 2015 the total amount of municipal solid waste produced in the United States was 262.4 million tons. On a per capita basis, 4.48 pounds of waste was produced per person per day in 2018. That trash consisted of paper, glass, rubber, plastic, metals, food, and textiles among ...

Stabilisation of municipal solid waste in bioreactor landfills - an overview
The basic purpose of operating landfills as bioreactors is to enhance the waste degradation and to stabilise the waste in shorter time period as compared to conventional dry tomb landfills. This paper presents an overview of bioreactor landfills in terms of various factors affecting stabilisation of municipal solid waste. Moisture is considered to play a critical role in the biodegradation of the ...

Odor Control Systems for Leachate Plant
Leachate is water that has percolated through a solid and leached out some of the components. It is formed when liquid passes through a landfill and gets mixed with degraded waste and suspended materials. Leachate has high levels of odor-causing compounds. These components are harmful to human health. It is actually toxic when inhaled. This, in turn, creates a problem for the areas nearby homes ...

Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water
Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other liquids ...

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 ...

Solid waste characterisation and the assessment of the effect of dumping site leachate on groundwater quality: a case study
In this study, the characterisation of the solid waste and the effect of the leachate from the major dumping site in Perungudi, Chennai city, on groundwater is investigated. Various physical and chemical parameters were estimated: this includes pH, total hardness, electrical conductivity, and total dissolved solids, major cations such as Ca2+, Mg2+, Na+, and K+, major anions such as NO32−, Cl−, ...

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 Services-Roosevelt Regional Landfill ...

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 ...

Solid waste management in Patna – analyses of ambient air and ground water pollution
Municipal Solid Waste (MSW) in Patna is disposed of in an unscientific manner without considering environmental impacts. The wastes are dumped in the low-lying areas without compliance of the MSWM Rules, 2000. The dumped wastes are mixed with biomedical wastes making it hazardous. Ambient air quality and ground water were analysed at two dump sites to study the possible impacts of MSW. The ...

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 ...

Lysimeter comparison of the role of waste characteristics in the formation of mineral deposits in leachate drainage systems
A common operational problem in leachate collection systems is clogging due to the formation of deposits within pore spaces and collection pipes. The role of co-disposal of municipal solid waste (MSW) and combustion residues from waste-to-energy (WTE) facilities in clogging is evaluated in this paper. Five parallel lysimeters were operated in monofill or co-disposal mode using MSW, WTE combustion ...

Challenges at MSW Landfill Sites
Covering the day’s trash at the landfill Today’s municipal solid waste (MSW) landfills are much more than places to dump household trash. They’re engineered facilities that are designed to hold and isolate the trash from the environment and are governed by both federal and state regulations. Landfill designers and operators face two main challenges to the integrity of ...
