Thermophilic anaerobic digestion of methanol in UASB reactor
Water Science and Technology, 2001 A 5.1 L laboratory scale upflow anaerobic sludge bed (UASB) reactor was operated at 55°C over 130 days in order to investigate the feasibility of treating methanol-containing wastewater under thermophilic conditions, focussing on start-up and process stability.

UASB-reactor in the fruit juice industry
Water Science and Technology, 1997 This paper presents experiences with a full scale UASB-reactor in a fruit juice factory. The focus is on demonstrating that a UASB-reactor is as suitable for campaign industries running only 2 months a year with higher concentrated wastewater as well as for the time outside the campaign when the wastewater concentrations are very low (average COD 1000 ...

Quantitative Detection of Syntrophic Fatty Acid-degrading Bacterial Communities in Methanogenic Environments [PDF]
, 2015 In methanogenic habitats, volatile fatty acids (VFA), such as propionate and butyrate, are major intermediates in organic matter degradation. VFA are further metabolized to H2, acetate and CO2 by syntrophic fatty acid-degrading bacteria (SFAB) in ...

Water Science and Technology, 1986 The state of knowledge on the microbiological aspects of granular methanogenic sludge in upflow anaerobic sludge blanket (UASB) reactors is reviewed. Granular methanogenic sludge has been observed in a variety of upflow reactors, which is in agreement with the hypothesis that these systems select for well settling sludges. In methanogenic UASB reactors

Developing a multi-criteria decision support system based on fuzzy analytical hierarchical process (AHP) method for selection of appropriate high-strength wastewater treatment plant [PDF]
Advances in Environmental Technology, 2019 The selection of an optimum treatment process for high-strength wastewater is complicated. Familiarity with wastewater treatment methods is not enough to design a plant and requires a multidisciplinary knowledge base.

Controlling granular sludge floatation in uasb reactors
Water Science and Technology, 1997 Granule floatation may occur at higher organic loadings, resulting in a loss of active granules and a decrease in the treatment capacity of UASB reactors. Granular sludge sampled from full-scale UASB reactors was studied to investigate the mechanism of granule floatation.
