TLDR
The results showed that the sequential anaerobic-aerobic process might remove above 90% of COD and near to 100% of NH4+ -N from leachate under the optimum organic loading rate (OLR).About:

Nitrogen balance in and export from agricultural fields associated with controlled drainage systems and denitrifying bioreactors
TL;DR: In this paper, the authors measured daily tile flow and nitrate-N (NO 3 -N) concentrations and calculated cumulative N loss from the tile water at both free (FD) and controlled drainage (CD) patterned tile systems.
Journal ArticleDOI
Comparison of aerobic and anaerobic degradation of municipal solid waste in bioreactor landfills
TL;DR: Results of experiments indicated that aerobic reactor had higher organic, nitrogen, phosphorus and alkali metal removal efficiencies than the anaerobic one and stabilization time considerably decreased when using aerobic processes with leachate recirculation compared to theanaerobic system with the same recirculating scheme.

Nitrogen management in landfill leachate: application of SHARON, ANAMMOX and combined SHARON-ANAMMOX process.

TL;DR: The combined SHARON-ANAMMOX process for municipal landfill leachate treatment is a new, innovative and significant approach that requires more research to identify and solve critical issues.

Methane oxidation in landfill waste biocover soil: kinetics and sensitivity to ambient conditions.
TL;DR: The results showed that the optimal composition of waste biocover soil as a landfill cover material for CH(4) oxidation was original pH value, 45% moisture and a particle size of ≤ 4mm, while NH(4)(+)-N had a greater stimulating action as nutrient at lower concentrations and inhibitory effect at higher concentrations on CH( 4) oxidation.
Journal ArticleDOI
Comparing field investigations with laboratory models to predict landfill leachate emissions.
TL;DR: The results indicate that the flow of water in field-scale landfills is less uniform than in laboratory reactors, and the stock of materials remaining in the landfill body, and thus the long-term emission potential, is likely to be underestimated by laboratory landfill simulations.

Landfill bioreactor design and operation
TL;DR: This book discusses the evolution of landfills for Waste Management Landfills as Bioreactors as well as the design of Landfill Treatment and Reclamation Strategies, and some of the strategies used to achieve this goal.

A field investigation of the quantity and quality of leachate from a municipal solid waste landfill in a Mediterranean climate (Thessaloniki, Greece)
TL;DR: In this paper, the composition of leachates varied widely depending mainly upon their degree of stabilization and upon their seasonal production, representing the influence of different climatic conditions, and suggestions have been proposed for the subsequent treatment of leaches, based upon hydrological and leachate quality data, in order to avoid environmental deterioration problems caused by direct disposal.
Journal ArticleDOI
Temporal variation of leachate quality from pre-sorted and baled municipal solid waste with high organic and moisture content.
TL;DR: The results indicated that: (1) pre-sorting and baling of the waste did not hinder waste stabilization; and (2) the high organic and moisture contents resulted in an extremely strong leachates, particularly at the onset of biodegradation processes, which can affect the leachate treatment facility.
Journal ArticleDOI
Simultaneous organic and nitrogen removal from municipal landfill leachate using an anaerobic-aerobic system.
TL;DR: An anaerobic-aerobic system including simultaneous methanogenesis and denitrification was introduced to treat organic and nitrogen compounds in immature leachate from a landfill site to enhance the nitrification rate in the following aerobic reactor.

Biological nitrogen removal from municipal landfill leachate: low-cost nitrification in biofilters and laboratory scale in-situ denitrification
TL;DR: In conclusion, nitrification in a low-cost biofilter followed by denitification in a landfill body appears applicable for the removal of nitrogen in landfill leachate in colder climates.
