Characteristics and Treatment of Landfill Leachate and Optimization of Leachate Oxidation with Fenton's Reagent
The purpose of this study was to characterize the leachate from a landfill in Pennsylvania that had been pretreated by activated sludge and propose the most efficient treatment for this effluent. These samples had been pretreated in a sequencing batch reactor that also was operated to remove …

In-situ passive treatment of municipal solid waste (MSW) leachate using a modified drainage leachate collection system (LCS)
… investigation of in-situ treatment of synthetic leachate representative of that generated by a municipal solid waste (MSW) landfill. The overall objective is to evaluate alternative designs and operating procedures for effective leachate collection in conjunction with efforts to accelerate waste …

Carbon Nanotube Behavior in Represntative Old Leachate
… fate within landfills will be dictated by leachate composition. Typically, mature landfill leachate contains high concentrations of refractory dissolved organic matter and high electrolyte concentrations. Studies have shown that organic matter and electrolyte concentration and composition …

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 …

In-situ Ammonia Removal Of Leachate From Bioreactor Landfills
… the ammonia-nitrogen concentration found in the leachate. The concentrations of ammonia-nitrogen tend to increase beyond concentrations found in leachate from conventional landfills because recirculating leachate increases the rate of ammonification and results in accumulation of higher levels of …

Sustainable landfill leachate treatment using a willow vegetation filter
… 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 growth were …

Numerical modelling of leachate production and movement within landfill sites
… processes of the production and management of leachate from landfill sites. The existing landfill leachate management models are reviewed and analysed on the basis of their applicability and effectiveness, identifying a number of important deficiencies in these models. These models simplify the …

Anaerobic digestion comparison of manure leachate by high-rate anaerobic reactors
… (MSAD) has been developed to obtain high organic leachate from high solids organic waste, thus high-rate anaerobic reactors can be fed by manure leachate, which can be obtained from a leachate bed reactor. Such configuration not only makes feasible the application of high-rate reactors to treat …

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 …
