Advanced Oxidation Processes (AOPs) for reduction of organic pollutants in landfill leachate: a review
Uncontrolled municipal landfill leachate during landfilling can seriously pollute groundwater, surface water and soil. Over the past decades, a variety of Advanced Oxidation Processes (AOPs), primarily utilising hydroxyl radicals to effect water purification, have been frequently investigated for treatment of landfill leachate. This paper first summarises the typical characteristics of organic ...

Influence of magnetic treatment on the improvement of landfill leachate treatment
Magnetic treatment is an alternative simple approach by which landfill leachate treatment could be improved. The purpose of landfill leachate treatment is to remove the Suspended Solids, Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD). Based on experiment by using circulation flowing system with a magnetic strength of 0.55 T, it was shown that the leachate quality could be ...

Inhibition kinetics and granular sludge in an ANAMMOX reactor treating mature landfill leachate
The present study reports the inhibition kinetics and granular sludge in an anaerobic ammonium oxidation (ANAMMOX) – up-flow anaerobic sludge blanket reactor fed with diluted mature landfill leachate. The activity of ANAMMOX bacteria was inhibited by addition of mature landfill leachate, but gradually adapted to the leachate. The system achieved efficient nitrogen removal during 65–75 d and ...

Removal of COD and colour from old-landfill leachate by Advanced Oxidation Processes
This research aims to apply Advanced Oxidation Processes (AOPs) using ozonation, combined O3/H2O2 and Fenton reaction for simultaneous COD and colour removal from old-landfill leachate. The efficiencies of the AOPs for both COD and colour removal could be ranked in this order; Fenton reaction > O3/H2O2 > O3. The Fenton reaction, operated at pH 3 could significantly remove more than 85% of colour ...

Electrochemical treatment of semi-aerobic landfill leachate using Response Surface Methodology (RSM)
This research investigated the effectiveness of electrochemical treatment in treating semi-aerobic landfill leachate. The electrolytic reactor assembly included a pair of aluminium electrodes, a power supply and NaCl as electrolyte. The interactive effects of initial COD, current density and reaction time on treated leachate quality were studied. Regression equations were developed using ...

Assessment of genotoxicity of landfill leachate by comet assay using golden pothos (Epipremnum aureum)
Landfill leachate is a complex mixture of various inorganic and organic compounds. The possibility of using comet assay in relation to pollutant analysis for characterising genotoxicity of landfill leachate was studied. Golden pothos (Epipremnum aureum) was used as the biomonitor with comet assay. Polluted water of fresh and old leachates in different gradients was employed in the experiments. ...

Effects of dissolved organic matter in landfill leachate on photodegradation of environmental endocrine disruptors
The direct and indirect photolysis of Environmental Endocrine Disruptors (EEDs) was investigated with and without Dissolved Organic Matter (DOM) extracted from landfill leachates. The results indicate that degradation of EEDs followed a pseudo-first-order. Photosensitised transformation of EEDs occurred because of the light absorption of DOM under sunlight irradiation while distinctive ...

Multiple responses analysis and modeling of Fenton process for treatment of high strength landfill leachate
Landfill leachate is one of the most recalcitrant wastes for biotreatment and can be considered a potential source of contamination to surface and groundwater ecosystems. In the present study, Fenton oxidation was employed for degradation of stabilized landfill leachate. Response surface methodology was applied to analyze, model and optimize the process parameters, i.e. pH and reaction time as ...

The effect of urban landfill leachate characteristics on the coexistence of anammox bacteria and heterotrophic denitrifiers
Heterotrophic denitrification coexists with the anammox process contributing to N removal owing to the biodegradable organic matter supply from urban landfill leachate and the decay of microorganisms. Both biomasses consumed nitrite increasing the nitrite requirements of the system. The aim of this paper is the study of the causes which induce the system to decrease nitrogen removal efficiency. ...

The removal of ammonia from sanitary landfill leachate using a series of shallow waste stabilization ponds
This study evaluated the efficiency of a shallow (0.5 m deep) waste stabilization pond series to remove high concentrations of ammonia from sanitary landfill leachate. The pond system was located at EXTRABES, Campina Grande, Paraiba, Northeast Brazil. The pond series was fed with sanitary landfill leachate transported by road tanker to the experimental site from the sanitary landfill of the City ...

Ocean bacteria: performance on CODCr and NH4+-N removal in landfill leachate treatment
An experiment was carried out to investigate the performance of mixed ocean bacteria, isolated from the ocean sediment, on landfill leachate treatment. In this treatment, ocean bacteria were the only constituent added to remove organics and NH4+-N. Given their considerable influence on wastewater purification, factors such as inoculum, initial pH, processing time and oxygen condition, ...

Co-treatment of old landfill leachate and municipal wastewater in sequencing batch reactor (SBR): effect of landfill leachate concentration
Sequencing batch reactor (SBR) was assessed for direct co-treatment of old landfill leachate and municipal wastewater for chemical oxygen demand (COD), nutrients and turbidity removal. Nitrogen removal was achieved by sequential nitrification and denitrification under post-anoxic conditions.
