Treatment of Brewery Effluent by UASB Process
Journal of Environmental Engineering, 1990A five-month pilot study was conducted to examine the effectiveness of the upflow anaerobic sludge blanket (UASB) process for the treatment of effluent from a brewery in rural China. Results indicate that the process operated at 26°C could reduce over 89% of chemical oxygen demand (COD) and 92% of five-day biochemical oxygen demand (BOD\d5) from the ...

Histological Analysis of Microstructure of UASB Granules
Journal of Environmental Engineering, 1994A histological method was demonstrated for the microscopic analysis of granules from upflow-anaerobic-sludge-blanket (UASB) reactors. Granules were first fixed with formaldehyde and embedded in paraffin, before being sectioned by a microtone to a thickness of 3–5 pm.

An integral dynamic model for the UASB reactor
Biotechnology and Bioengineering, 1986AbstractIn this article a dynamic model of a continuous working UASB reactor is described. It results from the integration of the fluid flow pattern in the reactor, the kinetic behavior of the bacteria (where inhibition and limitation were taken into account), and the mass transport phenomena between different compartments and different phases.

Study on hydrogen production with hysteresis in UASB
Chemosphere, 2004This paper uses a 10-l UASB (upflow anaerobic sludge blanket) bench-scale reactor to treat the esterification wastewater of a polyethylene terephthalate manufacturing plant. Two organic loading rates are used to evaluate the effect on H2 production of temperature gradually step-down and step-up in the range of 11-25 degrees C. Experimental results show

Technical review on the UASB process
International Journal of Environmental Studies, 1991This paper presents a comprehensive review of the UASB wastewater treatment process. Factors affecting granulation of the anaerobic sludge, start‐up of the process and operation of UASB reactor are analyzed. Criteria about design and construction of the UASB reactor are described, and studies on mathematical modeling of fluid flow pattern, sludge ...

Preservation characteristics of UASB Sludges
Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1997Abstract Anaerobic 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.

A two-phase anaerobic digestion process (UASB-UASB) for simulated sewage sludge
2008The objectives of this research program were to demonstrate the feasibility and effectiveness of a “two-phase” anaerobic sewage sludge stabilization (UASB-UASB) process. A bench-scale experiment, consisting of two completely mixed sealed upflow anaerobic (A-UASB and M-UASB) reactors, designed to operate inside a walk-in temperature controlled room at ...

Performance of UASB reactor in the biotreatment of 1,1,2-Trichloroethane
Journal of Environmental Science and Health, Part A, 2012This article aims to examine the performance of bench-scale Upflow Anaerobic Sludge Blanket (UASB) reactor operated under varying operating conditions, during the treatment of simulated wastewater containing 1,1,2-Trichloroethane (TCA). Initially, reactor R1 (control) and reactor R2 (test) containing TCA were operated at 5 different Hydraulic Retention
