With the growth of sewage collection networks, sludge production in Sewage Treatment Plants (ETEs) has been growing steadily as these networks are expanded and new treatment plants are deployed. The sludge generated in the ETEs presents a composition of constituents that can pose risks to the health of the population and the environment, and it is necessary to make adequate final disposal of this residue or to reuse the nutrients that can be obtained in membrane filtration processes. Recent studies have shown that nutrient recovery from sewage sludge can be performed in Anaerobic Membrane - AnMBR systems, which include a feed reservoir, an anaerobic digester, a membrane filtration module and a permeate storage reservoir. Some factors contribute to the performance of the bioreactor process, making constant monitoring of some parameters necessary. The constant monitoring was performed through the automation of the system, using the micro controller Arduino board, connected to pressure and temperature sensors, where values are displayed through reports generated by the software. The software shows information in real time, but also provides a tool where you can query data from the bioreactor according to the desired date. At the end of the research it was possible to verify that the software facilitates the storage and processing of data, offering a better management of information of extreme importance in the aid of decision making in the management of membrane bioreactors.
Com o crescimento das redes de coleta de esgotos, a produção de lodos em Estações de Tratamento de Esgotos (ETEs) vêm crescendo continuamente à medida que estas redes são ampliadas e novas estações de tratamento são implantadas. O lodo gerado nas ETEs apresenta uma composição de constituintes que podem trazer riscos para a saúde da população e ao meio ambiente, sendo necessário realizar disposição final adequada a este resíduo ou reaproveitar os nutrientes que podem ser obtidos em processos de filtração por membranas. Estudos recentes demonstram que a recuperação de nutrientes do lodo de esgoto pode ser realizada em sistemas de Biorreatores Anaeróbios de Membrana - AnMBR, que incluem um reservatório de alimentação, um digestor anaeróbio, um módulo de filtração de membrana e um reservatório de armazenamento de permeado. Alguns fatores contribuem no desempenho do processo do biorreator, tornando necessário o acompanhamento constante de alguns parâmetros. O acompanhamento constante foi realizado através da automação do sistema, utilizando a placa micro controladora Arduino, conectada a sensores de pressão e temperatura, onde os valores são exibidos através de relatórios gerados pelo software. O software mostra informações em tempo real, como também disponibiliza uma ferramenta onde é possível consultar dados do biorreator de acordo com a data desejada. Ao término da pesquisa foi possível constatar que o software facilita a armazenagem e tratamento de dados, oferecendo um melhor gerenciamento das informações de extrema importância no auxílio à tomada de decisão na gestão de biorreatores de membrana.

Full textThe preoccupation with the quality of water resources is intensifying studies about advanced technologies for wastewater treatment. A promising technology in Brazil is the membrane bioreactors (MBR), due its capacity to operate with high application rates and may also obtains a treated effluent able to reuse. Thus, this work aimed to study a MBR with external membrane module. Firstly, it has been determined operational parameters by preliminary studies, namely: membrane compactation, hydraulic permeability and permeability to activated sludge. After that, the MBR was setting. Then, it was initially fed a synthetic wastewater and, then, with tannery wastewater collected after conventional treatment. Operating with synthetic wastewater, it was obtained a reduction of more than 95% for COD and turbidity. The operation with tannery wastewater post treatment resulted in efficiency of 46%, 88%, 16%, 67% and 48% for COD, BOD5, TKN, Total-P and chromium, respectively. Moreover, after 15 days of operation, the system has stabilized with high permeate flux: 43 L/m².h.

Full textThe use of membranes processes for wastewater treatment has increased in recent decades, with focus on optimizing these systems, requiring less physical space and meeting increasingly stringent environmental quality criteria. Conventional treatment processes using activated sludge units, have been replaced by systems with submerged membrane modules, called Membrane Bioreactor - MBR. The problems with the use of the membranes in these conditions are related to the reduction of the permeate flow (J20) and the increase in the total resistance (Rt) along the running time of the filtration, associated with different block mechanisms, due to fouling of the membranes with biosolids. This study analyzes the filtration behavior of three activated sludges coming from different sources: the petrochemical industry, hospital and landfill leachate. The diversity of the composition of these effluents allowed the analysis the declining behavior of J20 and the increasing behavior of Rt throughout the filtration tests, conducted with four hours duration time. For each sludge three concentrations of Total Suspended Solids (TSS) were tested: 8,000, 17,000 and 23,000 mg / L, as well as three transmembrane pressures (TMP): 180, 240 and 300 mbar. The sludge were characterized by determining viscosity, density, physical characteristics of biosolids (average and effective diameters, coefficients of uniformity and curvature), and the quantification of the EPS fractions concentration (Extracellular Polymeric Substances). The bench tests were performed with hollow fiber submerged membrane modules, manufactured in order to ensure uniformity. The procedures were performed in a standardized way, including the promotion of turbulence through forced aeration. The results allowed the analysis of the permeate flux decline behavior and the increasing of the total resistance, comparing these ratios to the variations in the concentrations of TSS and TMP for each sludge tested and also allowed the analysis of relations between the distinct sludges. Values of the Modified Fouling Index - MFI and blocking mechanisms that occurred during the filtrations for each sludge were also analyzed. The results indicate that both the variation of the TSS concentration and the TMP do not lead to significant differences in J20 values, but do generate distinct final Rt values. Thus, one possible conclusion is that increasing TMP, with the objective of increasing J20 in a real system is not an effective action and would result in the increase of energy costs, due to the increase of Rt. No correlation could be established between the MFI results and the parameters TSS and TMP. However, it was possible to establish correlations between the fall of J20 and the concentrations of EPS, as well as viscosity and density. Predominant blocking mechanisms were identified, allowing the conclusion that cake filtration prevails in most testing situations.

Biorreatores com Membranas Submersas (BRMS) são, atualmente, reconhecidos como opção viável para o tratamento de esgotos sanitários e o reúso de águas. Apesar disso, a tecnologia é geralmente vista como de alto investimento quando comparado a sistemas convencionais de tratamento de esgoto, sobretudo pelo maior gasto energético com aeração do sistema. Porém, BRMS quando operados sob condições específicas para nitrificação e desnitrificação simultâneas (NDS), é possível obter um efluente de elevada qualidade com menor custo, devido a menor necessidade de aeração. Nesse sentido, a operação do sistema de BRMS com o processo de NDS pode aumentar a utilização desta tecnologia no tratamento de esgoto sanitário. Neste contexto, este trabalho teve por objetivo principal avaliar a remoção de nitrogênio via NDS em diferentes concentrações de oxigênio dissolvido (OD) em uma unidade piloto de um Biorreator de Membranas Submersas tratando esgoto sanitário. Para isso, o experimento foi dividido em três Fases de acordo com a concentração de oxigênio dissolvido no licor misto: Fase I (2,3 mgO2/L), Fase II (0,8 mgO2/L e Fase III (0,3 mgO2/L). Foram alcançadas elevadas eficiências de remoção de material orgânico, independente das variações na concentração de OD, DBO5 com valores médios de 98%, 97% e 98% e DQO de 95%, 96% e 95% para as Fases I, II e III, respectivamente. A remoção média de nitrogênio total obtida foi 33% na Fase I, 60% na Fase II e 50% na Fase III. Onde a remoção via NDS foi responsável por 60%, 78% e 74% do total removido para as Fases I, II e III, respectivamente. A remoção de nitrogênio amoniacal não foi limitada devido as baixas concentrações de OD e houve acúmulo de NO2-. O sistema operou sob baixos valores de pressão transmembrana durante todo o período, porém foi encontrada diferença significativa nos valores da Fase III em relação às Fases I e II. Houve uma redução significativa na permeabilidade da membrana quando a concentração de OD no licor misto foi reduzida para 0,3 mg/L, porém sem efeito significativo quando a concentração de OD foi de 0,8 mg/L. Foram observados maiores valores de SPE ligado na Fase III em relação às demais, principalmente na fração de carboidratos que pode estar diretamente ligada a taxa de fouling. Foi possível alcançar remoção de NT em OD de 0,8 mg/L (Fase II) sem causar um impacto negativo no desempenho das membranas, sendo esta fase a mais adequada para a ocorrência do processo de NDS em BRMS.
Submerged Membrane Bioreactors (SMBR) are actually, recognized as viable option for wastewater treatment and reuse. Nevertheless, this technology is generally viewed as a high investment compared to conventional sewage treatment systems, especially for greater energy requirement for aeration system. However, SMBR when operated under specific conditions for simultaneous nitrification and denitrification (SND) it is possible to obtain a high quality effluent with lower compared to the conventional configuration because of less need for aeration. Therefore, the operation of the system SMBR with the NDS process can increase the utilization of this technology in the wastewater treatment. In this context, this study aimed to evaluate the removal of nitrogen via SND under different dissolved oxygen concentrations (DO) in a pilot of a SMBR treating wastewater. For this, the experiment was divided into three phases according to the concentration of dissolved oxygen in the mixed liquor: Phase I (2,3 mgO2/L), Phase II (0,8 mgO2/L and Phase III (0,3 mgO2/L). Were achieved high organic matter removal efficiencies regardless of fluctuations in DO concentration in terms of BOD5 average values of 98%, 97% and 98% and COD average values of 95%, 96% and 95% for Phases I, II and III respectively. The average total nitrogen removal was 33% in Phase I, 60% in Phase II and Phase III 50%. Where the removal means SND is responsible for 60%, 78% and 74% of the total removed for Phases I, II and III respectively. The removal of ammoniacal nitrogen is not limited by the low DO concentrations and there was accumulation of NO2- in Phase III. The system operated under low transmembrane pressure values throughout the period, but significant difference was found in the values of Phase III in relation to phases I and II. There was a significant reduction in membrane permeability when the DO concentration in the mixed liquor was reduced to 0.3 mg/L, but without significant effect when the DO concentration was 0.8 mg/L. It was observed highest bound EPS values in Phase III in relation to the others, mainly in the fraction of carbohydrates that can be directly linked to fouling rate. Satisfactory NT removal was achieved when concentration DO was 0.8 mg/L (Phase II) without causing a negative impact on the performance of membranes, being this phase the most suitable for the occurrence of the SND process in SMBR.

Full textThe integration of the membrane separation technology in conventional processes of activated sludge represents an important innovation in the technology evolution of biological wastewater treatment. This work evaluated the performance of a submerged membrane bioreactor, provided with a membrane backwashing system, used for the continuous treatment of a synthetic wastewater. The hollow fiber membranes were manufactured by polyetherimide material. Different aeration and backwashing cycles conditions were tested. The membrane bioreactor system seems not to answer satisfactorily to the strategies to limiting fouling. The continued and accented decrease of the permeate flux over time were observed for all the conditions tested, with final permeate fluxes approached of 10 L.m-2.h-1. The longer experiments, 80 hours of duration, presented a decrease of 50% of the initial permeate flux in the best tested experimental conditions, not being observed a steady-state permeate flux. It was verified that the synthetic effluent (whey based) has some influence in the fouling formation, since even in the absence of activated sludge it was observed a permeate flux reduction similar to that observed on the others experiments. However, intense fouling still was observed after changing the synthetic effluent for another more simple (glucose and peptone based). The experimental data were adjusted to the Hermia model. Fouling mechanism follows the complete and intermediate blocking models at the beginning of the permeation stage and the cake formation model for the later stage. A parallel study of the EPS adsorption in polyetherimide membranes was also carried out. Polyetherimide membrane presented great EPS adsorption with high permeability reduction. An EPS adsorption model was proposed and it showed efficient for experimental data analysis, even when other authors data were analyzed.

Full textThe Membrane Bioreactor (MBR) process was developed in the late 1960. The system consists in a combination of biological process and membrane separation mechanism, and the advantages with respect of conventional treatment are the higher treatment efficiency and a smaller area of installation for the same treatment capacity. The main limitation of this process is the membrane fouling, in a way that air flow rate represents an important operating condition to prevent the fouling formation in Submerged Membrane Bioreactors (SMBR). In this sense, the aim of this work is to evaluate the effects of hydrodynamic conditions on process performance, such as air flow rate, packing density of the membrane module and aeration geometry. The system used consists in a pilot-scale SMBR, which operates at constant pressure and continuous mode during a period of 4 days. The modules were built with hollow fiber polymeric microfiltration membrane and the material is poly(ether)imide (PEI). For the three different air flow rates studied (2, 5 and 8 L.min-1), results showed there is a limit value for this parameter, in which above this value a better performance will not be obtained, even can be worse. The air flow rate of 5 L.min-1 presented the best performance, followed by 8 and 2 L.min-1. The module packing density study for two diameters (0.75 and 1 inch), the best result was observed in the larger diameter module, because lower packing density causes more space between fibres, increasing the aeration homogeneity inside de fibre bundle. Both aeration geometry tested showed similar permeate flows, indicating the different geometry used did not affect the performance process. The aerators constructed with the hollow fibers did not promote aeration homogeneity inside the bundle, and new aeration geometry must be projected. For all hydrodynamics conditions, the system treatment was efficient in removing organical matter, since the removal for TOC and COD was 96% and 93%, respectively. Permeate properties such as electrical conductivity, pH and turbidity measurements presented minor variations than effluent properties measurements, showing the system capacity to withstand with feed stream variations.

The treatment of sewage sludge is a challenge for environmental sanitation due to its difficulty to stabilize and large number of undesirable elements. On the other hand, it is found in its composition a high concentration of nutrients that can be reused in the nature in a beneficial way, but that end up being wasted in the conventional treatments. In the present work the treatment of sewage sludge in an anaerobic dynamic membrane bioreactor (AnDMBR) was carried out, in which it was possible to verify that the use of the dynamic membrane provided an excellent performance for the sludge filtration, producing turbidity permeate below 1 NTU after the formation of the separation layer. In addition, 53.2% of the phosphorus concentration and 35.6% of the nitrogen concentration were found in its composition, demonstrating that the use of this technology is a very interesting alternative for the recovery of these nutrients. As long as produced a less pollutant and nutrient-recovering permeate, there was also a marked stabilization of the concentrate, which showed a reduction of the organic fraction from 0.76 to 0.54 and the F/M ratio of 0.07 kgCOD/KgVSS to 0.02 KgCOD/KgVSS, furthermore a considerable methane production was observed.
O tratamento do lodo de esgoto consiste em um desafio na área de saneamento ambiental por se tratar de um resíduo de difícil estabilização e com grande quantidade de elementos indesejáveis. Por outro lado, é encontrada na sua composição uma elevada concentração de nutrientes que podem ser reutilizados na natureza de maneira benéfica, mas que acabam sendo desperdiçados nos tratamentos convencionais. No presente trabalho foi realizado o tratamento do lodo de esgoto em um biorreator anaeróbio de membrana dinâmica (BRAnMD), no qual foi possível verificar que a utilização da membrana dinâmica proporcionou um ótimo desempenho para a filtração do lodo, produzindo um permeado com turbidez abaixo de 1 NTU após o período de formação da camada de separação. Além disso, na sua composição foi encontrada 53,2% da concentração do fósforo afluente e 35,6% da concentração de nitrogênio, demonstrando, dessa forma, que a utilização dessa tecnologia consiste em uma alternativa bastante interessante para a recuperação desses nutrientes. À medida que produzia um permeado menos poluente e recuperava de nutrientes, verificou-se também uma estabilização acentuada do concentrado, que apresentou uma redução da fração orgânica de 0,76 para 0,54 e da relação A/M de 0,07 KgDQO/KgSSV para 0,02 KgDQO/KgSSV além de possibilitar uma considerável produção de metano.

O biorreator à membrana (BRM) permite a retenção da biomassa e microrganismos patógenos, promovendo maior eficiência no tratamento de efluente e segurança bacteriana no permeado. O efluente tratado apresenta boas condições de reúso. O trabalho desenvolvido nesta Tese utilizou o BRM submersa para o tratamento de um efluente sintético, avaliando-se seu desempenho hidrodinâmico e físico-químicos no controle da colmatação. Os estudos experimentais foram realizados no Laboratório de Génie des Procédés d#Élaboration des Bioproduits (GDPB), na Universidade Montpellier II, França. Os experimentos consistiram em acompanhar, durante 15 meses ininterruptos, o desempenho dos procedimentos sobre o plano de qualidade de tratamento de um efluente sintético e a evolução da colmatação da membrana. Os adjuvantes: cloreto férrico (FeCl3) e carvão ativo (CA) foram adicionados no tanque de alimentação, substrato, com o objetivo de aumentar o tamanho médio das partículas da suspensão biológica por floculação e adsorsão, para então verificar a minimização da colmatação das membranas.

Full textMembrane bioreactors (MBR) market has been showing high growth rates over recent years. However, membrane fouling drastically reduces MBR overall performance. Aeration promotes fouling mitigation, but at a high operational cost (up to 70% of the MBR energy demand) and it is optimally employed only in 10% of the cases. This created the need of studies focused on MBR hydrodynamic. Computational fluid dynamics (CFD) is a useful tool for hydrodynamic analysis. One of the first steps in finding a proper solution for numerical simulation is proposing a correct modelling. Among the phenomena to be modelled for MBR simulations, turbulence effects are probably one of the most important; nevertheless, no paper comparing the predictions based on the turbulence model choice for MBR simulations was found. In sight of that, this work aimed to verify the relevance of the choice of turbulence model for MBR simulations through CFD. Predictions of local velocities near membranes surfaces and of local shear stress on those surfaces, for two aeration rates (5 and 15 m³/h), employing k-ϵ with wall functions for high (aR) and low (bR) Reynolds number and k-ω SST with automatic wall functions, on the analysis of a MRB system, were compared between each other and with experimental and simulated data available in the literature. The velocity and shear stress temporal profiles showed oscillations with highly variable periods in some points, which required a long process real time to verify the local variables convergence. It was identified the need to give more importance to the definition of the time interval for experimental data collection in order to acquire reliable temporal means; also, one must properly analyze the temporal profiles for more definitive comparisons between predictions and experimental measurements. The differences, between experimental data and predictions, obtained through this work simulations were, in general, of similar order or smaller than the ones reported in the literature. Besides, more attention must be given to the turbulence modelling choices, since the predictions obtained here were highly sensitive to those choices, showing differences up to 21,6% among them.
