Co-degradation of resorcinol and catechol in an UASB reactor
Bioresource Technology, 2008Co-degradation of resorcinol and catechol was studied in a catechol acclimated up flow anaerobic sludge blanket (UASB) reactor. Synthetic binary aqueous solution having a total concentration of 1000 mg/L with the resorcinol/catechol (R/C) ratio of 1/19, 1/9, 3/17, 1/4, 1/3, 3/7, 2/3 and then 1/3 was fed at various time intervals to the UASB reactor ...

An examination of the structure of UASB granules
Water Research, 1995Sonication, staining and the analysis of extracellular polymers (ECP) were used to examine the structure of granules from pilot-scale and laboratory-scale anaerobic upflow sludge blanket reactors. The pilot-scale unit was part of the SERC Anaerobic Facility which was treating the liquors from the manufacture of instant coffee.

Granulation mechanism of a UASB reactor supplemented with iron
Anaerobe, 2008The aim of this paper was to propose a granulation mechanism in order to interpret all the experimental observations that arose during experiments on two UASB reactors, where one was supplemented with ferrous iron at a dose of 0.01 g Fe(2+) per g COD feed.

Hydrodynamic characteristics of UASB bioreactors.
Journal of environmental science & engineering, 2013The hydrodynamic characteristics of UASB bioreactors operated under different organic loading and hydraulic loading rates were studied, using three laboratory scale models treating concocted sucrose wastewater. Residence time distribution (RTD) analysis using dispersion model and tanks-in-series model was directed towards the characterization of the ...

Determination of granule size distribution in a UASB reactor
Journal of Environmental Management, 2008Granular sludge is the key factor for an efficient operation of an upflow anaerobic sludge blanket (UASB) reactor. In order to monitor the granularity of anaerobic sludge, the determination of the granule size distribution is of vital importance. For this reason, several techniques have been proposed; however, they are either tedious, imprecise or ...

Anaerobic digestion of baker's yeast wastewater using a UASB reactor and a hybrid UASB reactor
2010The 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.

Preservation characteristics of UASB sludges
2022Anaerobic treatment has become popular as an effective means for the treatment of high strength wastewaters, however, quantitative research on the preservation characteristics of anaerobic sludges is necessary when an anaerobic reactor is considered for use in industries operating intermittently.

Anaerobic degradation of butyrate in a UASB reactor
Bioresource Technology, 1995Abstract Wastewater with concentrated butyrate was treated in a 2·8 l UASB (Upflow Anaerobic Sludge Blanket) reactor at 37°C and pH 7·1–7·7. The process consistently removed 97–99% of COD for loading rates up to 31 g COD/l/day. Of all the COD removed, 94·5% was converted to methane; the average sludge yield was 0·037 g VSS/g COD.
