Leachate reactor landfill

Case 1 Anaerobic/Aerobic Treatment of Municipal Landfill Leachate in Sequential Two-Stage Up-Flow Anaerobic Sludge Blanket Reactor (UASB)/Aerobic Completely Stirred Tank Reactor (CSTR) Systems... [Pg.580]

The aerobic biofilter used in the study had a capacity of 10 L. The reactor was packed to 60% of the empty bed volume with Cosmo ball media. The biofilter was seeded with active innoculum taken from an active aerated lagoon of a nearby landfill leachate treatment. Fresh raw leachate was used as feed to the reactor at a rate of 5 L/d over 24h. The loading rates applied to the bioreactor were between 1.6 and 22.2 kg COD/m3d. Initial studies were conducted as a batch process lasting for a period of 24 d. Thereafter, the biofilter was fed continuously for a total period of 240 d. [Pg.584]

In Switzerland, where direct landfill of MSW is prohibited, all MSW has to be burned in incinerators and the bottom ash has to be stored in special controlled landfill sites (so called reactor deposits ). Re-use of today s BA is no longer practised because such BA is a heterogeneous random product (Lichtensteiger 1996) and elevated heavy metal concentrations in future leachates cannot be excluded (e.g., Staubli 1992). [Pg.412]

Otto Aqua-Tech HCR [High-Capacity Reactor] A high-intensity biological treatment process for purifying effluents from food processing, certain industrial processes, and landfill leachate. The waste is circulated rapidly through a vertical loop reactor, and air is injected at the top. Invented at the Technical University of Clausthal-Zellerfeld developed and commercialized by Otto Oeko-Tech. Eleven plants had been installed in Germany and Italy by 1991.

During 150-day laboratory experiment on sohd waste stabilization in simulated landfill bioreactors, pH of leachate in aerobic reactor rapidly increased from 5-6 to ca. 1 during 40 days, and then it was gradually growing to values of 8-9, until the end of the study. The pH values of leachate of the anaerobic reactor was less than 5.5 until the day 100, which reflected the accumulation of volatile acids generated in an acidogenesis phase. Next, the pH value slightly increased to ca. 6 at the end of the experiment (Sekman et al. 2011). [Pg.47]

The results of laboratory and field studies show that the aeration of waste deposited in landfills causes an accelerated reduction of the organic matter contained in the leachate compared to the anaerobic reactor. Chemical oxygen demand (COD), total organic carbon... [Pg.47]

The BOD /COD ratio—the measure of biodegrability of organic matter—reached the value 0.03 after one-year of experiment in the simulated aerobic landfill reactor, and ca. 0.8 in anaerobic one. The BOD /COD ratio determined in the anaerobic reactor at the end of the experiment (after 630 days) was ca. 0.15 (Erses et al. 2008). Borglin et al. (2004) claimed that BOD /COD ratio in leachate from aerobic and anaerobic reactors that had worked 365 days were 0.03 and 0.45, respectively. [Pg.48]
