Dispersion analysis of an acidogenic UASB reactor
Chemical Engineering Journal, 2008The dispersion behavior of an upflow anaerobic sludge blanket (UASB) reactor for acidogenesis was investigated, and its flow patterns were simulated. Compared with the single-zone axial-dispersion model (with squared difference from 130 to 450), a two-zone axial-dispersion model (with squared difference from 1 to 7) was found to be more appropriate for

Domestic wastewater treatment using a UASB reactor
Bioresource Technology, 1997Abstract The performance of a pilot-scale (55-l) upflow sludge blanket (UASB) reactor treating municipal sewage without any supplementary heating was examined in a 200-day trial. The flow rate to the digester was kept constant, giving a hydraulic retention time of 7.6 h.

Hydraulic Impact on Granules in UASB Reactors
Water Quality Research Journal, 1991Abstract 20 Litre UASB reactors, operated continuously, were used to study hydrodynamic influences on accumulation and settling characteristics of granules. Two experiments were performed. The effect of liquid upflow velocity in the reactor on granules was investigated in Experiment 1.

[Start-up of full-scale UASB reactors].
Huan jing ke xue= Huanjing kexue, 2002The UASB reactors treating high-temperature citric acid wastewater could be started up in the alternation of mesophilic and thermophilic ranges because the local climate changed greatly by seasons. The reactors were started up in mesophilic range, and the total efficiency of the two-stage reactors reached 77%-86%; when the temperature of reactors ...

Effect of monensin on UASB‐reactor performance
Environmental Technology, 1994Abstract 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 ...

Anaerobic Digestion Modelling and UASB Reactor Performance
1995Anaerobic digestion of lactose was carried out in a 1.5 L UASB reactor to estimate the parameters of a mathematical model. The mathematical model consists of one set of 4 algebraic and 5 differential equations that include a periodical partial purge. By using the mathematical model, lactose anaerobic digestion was simulated and statistically compared ...

Influence of extrinsic factors on granulation in UASB reactor
Applied Microbiology and Biotechnology, 2006The aim of this mini-review is to synthesize and analyze information on how the process of granulation is affected by environmental and operational conditions in the reactor. The factors reviewed are temperature, pH, alkalinity, organic loading rate, upflow velocity, nature and strength of substrate, nutrients, multivalent cations and heavy metals ...

Study on Scale-Up of UASB Reactor
1992The 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.
