Laboratory and pilot plant scale study on the electrochemical oxidation of landfill leachate.
Kinetic data regarding COD oxidation were measured in a laboratory scale cell and used to scale-up an electro-oxidation process for landfill leachate treatment by means of boron-doped diamond anodes. A pilot-scale reactor with a total BDD anode area of 1.05 m(2) was designed. Different electrode gaps in the laboratory and pilot plant cells resulted in dissimilar reactor hydrodynamics. Consequen...
متن کاملPesticides in Norwegian Landfill Leachates
Pesticides have been analyzed in 28 grab samples of untreated and 12 samples of treated leachate from eight Norwegian municipal solid waste (MSW) landfills, over a period of 10 years, with the purpose to screen for compounds and to evaluate the removal in different treatment systems. Also 1 grab samples of leachate sediments is included. A total of 12 compounds were detected. The most frequentl...
متن کاملAnalysis of Ammonia Toxicity in Landfill Leachates
Toxicity identification evaluation (TIE) phase I manipulations and toxicity test with D. magna were conducted on leachates from an industrial waste landfill site in Japan. Physicochemical analysis detected heavy metals at concentrations insufficient to account for the observed acute toxicity. The graduated pH and aeration manipulations identified the prominent toxicity of ammonia. Based on join...
متن کاملCombined anaerobic-aerobic treatment of landfill leachates
As a first step of treatment of landfill leachates (total COD – 1,430-3,810 mg/l, total nitrogen 90162 mg/l), a performance of laboratory UASB reactors has been investigated under mesophilic (30 C), sub-mesophilic (20 C) and psychrophilic (10 C) conditions. Under hydraulic retention times (HRT) of around 7 h, when the average organic loading rates (OLR) were around 5 g COD/l/day, the total COD ...
متن کاملTertiary treatment of landfill leachates by adsorption.
The leachates produced at the municipal solid waste (MSW) landfill of Asturias (Spain) were submitted to a biological treatment consisting of a pressurized nitrification-denitrification process followed by ultrafiltration. The effluent from this treatment plant has a high chemical oxygen demand : biochemical oxygen demand (COD : BOD( 5)) ratio (about 25 : 1). The COD values of the effluent are ...
