Analysis 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 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 کاملNitrifyers in constructed wetlands treating landfill leachates
Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. Constructed wetlands usually provide both shallow and deep areas with aerobic and anaerobic zones, which is suitable for nitrification followed by denitrification of the ammonium-rich leachates. Full-scale tre...
متن کاملAnalysis of Bhanpur Landfill Leachates : Investigation and Recommendation
Landfill leachates are not geographically specific; rarely acknowledge the impact of site specific parameters such as age, water balance, type of waste, landfill operation, etc.; and cover such large ranges that they are often of little use. Analysis of data from lined landfills in Bhopal was needed to provide useful information for the design and management of landfill leachates. Analyses were...
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 ...
