Managing landfill leachate using biological approach
Poor management of landfill would accompany with the production of leachate wastewater that would lead to environmental and public hazards. Hence, a study related to the use of biological treatment for leachate management was carried out.The research objectives of this research study were …

Nitrification of Landfill Leachate by Biofilm Columns
Landfill leachate characteristics vary depending on the operation type of the landfill and the age of the landfill. At landfills operated as bioreactors, where leachate recirculation is practiced, leachate ammonia nitrogen concentrations may accumulate to extremely higher levels than during single …

Evolution and degradation pathways of landfill leachate DOC and detection of groundwater landfill-leachate contamination using compound-specific isotope analysis
… (DOC) is a complex, yet major component of leachate and groundwater contamination derived from municipal solid waste burial. Here I use a new analytical technique for the analysis of 13C in specific compounds of DOC in leachate from the Trail Road Landfill (TRL) site, Ottawa, Ontario, in …

Chemical And Biological Treatment Of Mature Landfill Leachate
The challenges imposed on Voltage Regulator Modules (VRM) become difficult to be achieved with the conventional multiphase buck converter commonly used on PC motherboards. For faster data transfer, a decrease in the output voltage is needed. This decrease causes small duty cycle that is accompanied …

Sustainable landfill leachate treatment using a willow vegetation filter
… a willow vegetation filter for the treatment of landfill leachate is an environmentally and economically appealing solution for landfill operators. Investigations into the design and efficacy of the system, the effects of landfill leachate irrigation on soil ecology, soil chemistry and willow …

Management strategy of landfill leachate and landfill gas condensate
Studies were conducted to evaluate the impact of landfill leachate discharge on the operation of waste water treatment plants (WWTPs). Two aspects of interferences were found: one is UV quenching substances, which are bio-refractory and able to penetrate the biological treatment processes, …

Membrane Electrochemical Treatment of Landfill Leachate: Processes, Performance and Challenges
Landfilling is the most common approach to dispose of municipal solid wastes but inevitably leads to leachate formation. Persistent UV quenching substances (UVQS) in landfill leachate can affect the effectiveness of UV disinfection in municipal wastewater treatment systems when leachate …

The toxicity of Harmony Landfill Leachate to Green Hydra (Hydra viridiisma)
Harmony Landfill is a former industrial waste disposal site located adjacent to Harmony Creek in Oshawa, Ontario, Canada. During active disposal, from 1957 until 1980, approximately 1 million tonnes of waste were land-filled at the site. Although past environmental monitoring had indicated …

Low temperature biological treatment of a high ammonia municipal landfill leachate
… on the biotreatment of a high ammonia-N leachate and to optimize the control for the treatment at temperatures from 20°C to 4°C. Two identical bench-scale, single-sludge, pre-denitrification, activated sludge systems, with sludge recycle, were employed during this study. Each system …

CHARACTERIZATION OF SEPTIC SYSTEM WASTEWATER AND MUNICIPAL SOLID WASTE LANDFILL LEACHATE
… most domestic solid waste is disposed of in landfills, and domestic wastewater is treated by wastewater treatment plants (WWTPs) or onsite wastewater treatment systems (OWTSs). While OWTSs, the majority of which are conventional septic systems, account for the minority of wastewater treatment …

Advanced Technologies for Resource Recovery and Contaminants Removal from Landfill Leachate
Landfill leachate contains valuable, recoverable organics, water, and nutrients. This project investigated leachate treatment and resource recovery from landfill leachates by innovative methods such as forward osmosis (FO), bioelectrochemical systems (BES), and advanced oxidation. In this study, a …

Speciation and microbial transformation of chromium, arsenic and mercury in municipal landfill leachate
Transformation of heavy metals in landfill environment is currently not regulated by waste disposal guidelines. Chromium, arsenic and mercury speciation were investigated in municipal landfill leachate (MLL) to evaluate microbial transformation of the heavy metals in the landfill system. MLL is a …
-
Physical-chemical treatment of landfill leachate : technological performance, spectral characterization and cost estimations
The generation of landfill leachate is a significant result of landfilling. Because of the high concentrations of pollutants in leachate, disposal of raw or insufficiently treated landfill leachate can cause harm to the environment. Biological processes are inefficient for the treatment of …

Chemical characterisation of landfill leachate and its potential mobility through the Cape Flats sand
… at Coastal Park, a large, general waste landfill situated on the False Bay coastline above the Cape Flats Aquifer. The landfill was constructed without a liner, but with an average 2m separation of calcareous sand providing a "buffer" zone between the waste pile and the water table. Water …
