Monitoring of leachate quality is the essential measure in aftercare for evaluating landfill stabilization. Generally, the most common way of leachate monitoring is executed at the inlet of the leachate treatment facility. However, it does not necessarily reflect the actual state of the site. Thus, methodologies which focus on both the discharge, in order to determine when the post-closure care...

Advanced Oxidation Processes (AOPs) have been employed to degrade biorefractory organic matters. This study investigates the combination of classical Fenton reaction with electrochemical oxidation, the electro-Fenton process, for the treatment of semi aerobic landfill leachate, collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. The investigation has been carried out in batch re...

Landfill leachates are often treated on-site before disposal to municipal wastewater treatment plants, although variations in leachate composition and organic loading continue to have negative impacts on downstream treatment processes. Leachate samples were collected from four landfills both before and after on-site treatment to evaluate the extent of biological treatment. The samples vary in a...

The paper discusses the characteristics of leachate generated from municipal solid waste landfilling sites of Ludhiana City, Punjab (India). Leachate samples were collected and analyzed for various physico-chemical parameters to estimate its pollution potential. This study aims to serve as a reference for the implementation of the most suitable technique for reducing the negative environmental ...

Landfills receiving a mix of waste, including organics, have developed dramatically over the last 3-4 decades; from open dumps to engineered facilities with extensive controls on leachate and gas. The conventional municipal landfill will in most climates produce a highly contaminated leachate and a significant amount of landfill gas. Leachate controls may include bottom liners and leachate coll...

Background: The municipal solid wastes (MSWs) are disposed in open dumps, which have no leachate collection and removal system, in the Caspian region of Iran. Leachate readily reaches the nearby water resources such as streams, rivers, lakes, and sea. Therefore, understanding the quality and quantity of open dump leachate is vital to the proper treatment of leachate. Methods: The leachate samp...

Urban landfill leachate is a high strength wastewater characterized by high concentrations of recalcitrant organic compounds, ammonia and, increasingly, arsenic. The aims of this study were the review on membrane bioreactor, ion exchange and adsorption method for landfill leachate treatment. Membrane bioreactor (MBR) can be used for wastewater and landfill leachate treatment. The most important...

In most cases, the anammox process is used for nitrogen removal from reject water coming from dewatering of digested sludge. However, there are more industrial streams suitable for treatment by partial nitritation/anammox process. The landfill leachate may be a good example of such wastewater. Generally, landfilling is the most used solution for treatment of urban solid wastes. The problem with...
