Microaeration for hydrogen sulfide removal in UASB reactor

Bioresource Technology, 2014
The removal of hydrogen sulfide from biogas by microaeration was studied in Up-flow Anaerobic Sludge Blanket (UASB) reactors treating synthetic brewery wastewater. A fully anaerobic UASB reactor served as a control while air was dosed into a microaerobic UASB reactor (UMSB). After a year of operation, sulfur balance was described in both reactors.

UASB Treatment of Monosodium Glutamate Wastewater

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
Monosodium glutamate (MSG) wastewater is a very refractory case of high strength organic wastewater. To investigate the effect of operating variables on treatment of MSG wastewater, a laboratory scale study was conducted. The treatment of MSG wastewater was studied in a continuous flow anaerobic fluidized blanket (UASB) reactor. The effect of operating

Anaerobic digestion of baker's yeast wastewater using a UASB reactor and a hybrid UASB reactor

2010
The start-up and step-up operation of two 16-liter, continuously operated, upflow anaerobic reactors receiving baker's yeast wastewater is presented in this thesis. The two reactors (A and B) were almost identical in construction. Reactor A was a conventional upflow anaerobic sludge blanket (UASB) reactor, and reactor B was a hybrid reactor.

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 ...
