Analysis of the Landfill Leachate Treatment System Using Arima Models: A Case Study in a Megacity

open access: yesApplied Sciences, 2021
Leachate has been reported as the most significant source of landfill pollution. Predicting the characteristics of untreated and treated leachate may be useful during optimal scheduling of leachate treatment systems.

Experiment on monitoring leakage of landfill leachate by parallel potentiometric monitoring method

open access: yesScientific Reports, 2022
The accumulation of municipal solid waste (MSW) in landfills often becomes a serious pollution source of geological environment and groundwater. The geological environment is the carrier of the landfill, and also the main pollution object of the landfill.

Investigation into leachate transport in MSW landfills under pumping of vertical wells

open access: yesYantu gongcheng xuebao, 2018
Owing to the composition diversity of MSW and the compacted nature in landfills, the leachate transport in landfills is found to be dominated by the preferential flow and shows significant anisotropy (i.e., horizontal permeability higher than vertical ...

The effect of leachate input characterstics on the leachate collected after passage through a leachate collection system [PDF]

open access: yesThe 9th International Conference "Environmental Engineering 2014", 2014
A landfill leachate collection system (LCS) is intended to collect and remove leachate for treatment, thereby reducing the driving force (hydraulic head) for advective contaminant transport through the liner system. However the long-term performance of the granular drainage layer and pipes conducting the leachate to the sump(s) for collection is ...

Removal of ammoniacal nitrogen from municipal landfill leachate with floating Typha domingensis (Typhaceae)

open access: yesActa Biológica Colombiana, 2020
A promising method for the treatment of effluents is the use of floating macrophytes. Ammoniacal nitrogen is a typical compound present in urban landfill leachates and its removal is important due its toxicity to several organisms.

The Comet Assay for the Evaluation of Genotoxic Potential of Landfill Leachate

open access: yesThe Scientific World Journal, 2012
Genotoxic assessment of landfill leachate before and after biological treatment was conducted with two human cell lines (Me45 and NHDF) and Daphnia magna somatic cells. The alkali version of comet assay was used to examine genotoxicity of leachate by DNA

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

open access: yesAdvanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a
