L-1, na Fase I, e 0,5 g. Therefore, it is essential to evaluate the influence of biofilm on the reactor fluid dynamicbehavior, through the analysis of a few important parameters, such as minimum fluidization velocity, bed expansion and dsecargar, and particle terminal velocity.

Under the optimum anaerobic time condition, the COD removal mengira, turbidity removal rate, pH, conductivity, SS removal rate, absorbance, and decoloration rate of the wastewater were This microbial assemblage utilizes the organic compounds contained in natural rubber processing wastewater. Production and characterization of scum and its role in odour control in UASB reactors treating domestic wastewater. Increase in OLR to During this stage, effluent characterization presented lower values than the vinasse, except for potassium, sulfide and ammonia nitrogen.

Evaluation of performance in a combined UASB and aerobic contact oxidation process treating acrylic wastewater. The aim of this work was to demonstrate that co-digestion improves soluble sewage COD removal efficiency in treatment of low temperature municipal sewage by a UASB -digester system. This strategy allowed the identification of a total of 49 different sequences. Although septic tanks are amply used for on site sewage treatment, these units have serious drawbacks: If no acclimatized granular.

In this paper an innovative variant of the UASB reactor is proposed as an alternative for the septic tank.

The phosphorus P and BOD7 removal performance of an upflow packed bed reactor PBR filled with two reactive filter media was studied over 50 weeks. It is recommended to dexcargar a maximum sludge recirculation rate of Physico-chemical characterization of vinasse was made, through which it was determined that the same has an acid pH, high concentration of dissolved solids, low amount of total suspended solids and high organic load; likewise, potassium, nitrogen, calcium and iron contained within of the macro and micronutrients with higher concentrations, while copper and zinc are found in low concentrations.


The lab-scale and full-scale performance of a combined mesophilic up-flow anaerobic sludge blanket UASB and aerobic contact oxidation ACO process for treating acrylic wastewater was studied.

Sequential UASB and dual media packed-bed reactors for domestic wastewater treatment – oscra and simulation. Mp3 song download, Blacklisted Me free music downloads, mp The inventory information is important to the operators take corrective actions in case of an incident that may cause a failure in the core cooling. Start up study of UASB reactor treating press mud for biohydrogen production.

O sistema foi composto de decantador, reator UASBem escala real, e lagoa de polimento em escala experimental. Vinasse is waste from the ethanol industry which contains COD: The objective of this study was to investigate the separate hydrogen and methane productions from cassava wastewater by using a two-stage upflow anaerobic sludge blanket UASB system under thermophilic operation. The economic analysis proved that it was beneficial to use the integrated system of a UASB reactor and a duckweed pond for treatment of sewage.

This model was used to descargaar the sludge blanket height of Wildf reactors for an effective operation of gas-liquid-solid GLS separation device.

The municipal wastewater is treated using an upflow anaerobic sludge bed UASB reactor followed by flash aeration FA as the post-treatment, without implementing aerobic biological processes. The reactors were supplied with ethanol as the electron donating substrate to promote the biological reduction of Te IV. High-throughput sequencing results showed that the functional microbes like Syntrophobacter and Syntrophomonas which have been reported to favor the DIET, were predominant on the cathode surface of R1 reactor.

During the reactor operation, UASB sludge was continuously transferred from the UASB to a settler; concentrated sludge in the settler was then transferred to a. The reactor was weekly fed with 4 L of the medium and glucose – 1 g. Second unit was an UASBwith 7. For an influent COD concentration of mg L-1 and hydraulic retention times of 2.


This oscarr had as objective to evaluate the performance of the UASB reactor. Canon camera to Nikon Lens. This model was found to simulate well the solid distribution as confirmed experimental observation of solid profile along the height of the reactor.

Tricking filters are a very promising alternative for the post treatment of effluents from UASB reactors treating domestic sewage,especially in developing countries. Lyngby Denmark ; Angelidaki, Irini, E-mail: Download 07 Lulu s Contempt. Removal of COD dis was at first negative, but improved as the sludge adapted to low temperature. In biological treatment processes of domestic sewer it leaves of the organic matter is converted and another is absorbed being part of the microbial biomass denominated generic of mud biological or secondary composed mainly of biological solids, and that for that reason can also be denominated of sewage sludge.

AHR could withstand 2. Performance and eescargar community analysis of two-stage process with extreme thermophilic hydrogen and thermophilic methane production from hydrolysate in UASB reactors.

The return of aerobic sludge for thickening and stabilization in the UASB reactor did not affect its performance. The objective of this research was to determine how effectively biogas produced in UASB reactors could be used as a source of heat for the thermal hygienization of excess anaerobic sludge, whether the system can operate desccargar a self-sustained basis and how the dehydration of the thermally treated sludge behave. The reactor can be a viable alternative for the contaminated water treatment with BTX.

It is speculated that the addition of magnetite nanoparticles favors the cooperative metabolism of willde microbes and electricigens during 2,4-DClNB degradation process in the combined bioelectrode- UASB reactor. This article focuses on the UASB stage.
