Effect of monensin on UASB‐reactor performance

Environmental Technology, 1994
Abstract Monensin is an antibiotic with strong effects on acidogens and indirectly also methanogens; it could thus influence the activity and physical structure of UASB sludge. Therefore laboratory ‐scale UASB reactors were fed with synthetic wastewater and the effect of the addition of 0.1 mg 1‐1 of the ionophore on the performance and sludge bed ...

High strength sewage treatment in a UASB reactor and an integrated UASB-digester system

Bioresource Technology, 2008
The treatment of high strength sewage was investigated in a one-stage upflow anaerobic sludge blanket (UASB) reactor and a UASB-digester system. The one-stage UASB reactor was operated in Palestine at a hydraulic retention time (HRT) of 10h and at ambient air temperature for a period of more than a year in order to asses the system response to the ...

Study on Scale-Up of UASB Reactor

1992
The UASB (Upflow Anaerobic Sludge Blanket) reactor has been becoming popular since the early 1980s. The HRT of a well designed and correctly operated UASB reactor is only 1/10 1/20 that of those traditional anaerobic digestors, moreover, it is a net energy producing process.

Anaerobic treatment of leachates in UASB reactors

Journal of Chemical Technology & Biotechnology, 1992
AbstractLeachates from the solid urban wastes landfill of Asturias were characterized and treated in upflow anaerobic sludge blanket laboratory reactors. The highest percentage of COD removal was 88% for a hydraulic retention time of 2–4 days. Gas production was close to the theoretical values, with CH4 content up to 88%.

Kinetics of Biotransformation of 2,4-Dichlorophenol using UASB-Reactor

Environmental Monitoring and Assessment, 2004
Chlorophenol compounds are environmental pollutants that are both anthropogenic and xenobiotics. Some of these chemicals are carcinogens and are both toxic to a number biochemical processes. Biotransformation of 2,4-dichlorophenol (2,4-DCP) was studied in the presence of glucose on an upflow anaerobic sludge blanket reactor (UASB) using mixed culture ...

Enhancement of reactor performance and pelletization by reactor modification in UASB system

Journal of Environmental Science and Health, Part A, 2000
Abstract Reactor performance and pelletization characteristics by reactor modification in a UASB system were investigated. The modified lab UASB reactor with a settler comprising 50% of the total reactor volume showed better performance in removing soluble organics, as well as producing lower TSS effluents at higher loading rates.
