Modelling of Sulphate Reduction in Anaerobic Wastewater Treatment SystemsHaris, Abdul Unknown Date (has links)
Municipal wastewater and industrial wastewaters like those effluents from brewery, citric acid production, tannery, pulp and paper industry, and mussel processing contain sulphate ranging from 20 mg.L-1 to 11400 mg.L-1. When these wastewaters are treated in an anaerobic system like prefermentors or anaerobic digesters the sulphate is reduced to sulphide by sulphate reducing bacteria (SRB). The presence of sulphate reduction is not desirable as it may reduce methane yield due to partial substrate utilisation by SRB, causes system toxicity and the production of malodor H2S in the gas phase. In this thesis, the effects of operational conditions on sulphate transformation and assimilation was studied in a laboratory scale anaerobic wastewater treatment system. The laboratory scale system consisted of two reactors the first one a well-mixed fermentor (referred to as an acidogenic reactor) and the second an expanded granular sludge blanket reactor (referred to as a methanogenic reactor) with pH and temperature control. Two sets of studies were performed; in the first set both reactors were connected serially to represent a two-stage high-rate anaerobic treatment system. The system was fed molasses and operated at temperature of 35oC. The acidogenic reactor was controlled at pH of 6 while the methanogenic reactor was controlled at pH of 7.2 by automatic addition of caustic. In the second set of experiments only the first reactor was used to represent a prefermentor and the first stage of the two stage. The reactor was fed with glucose at various concentrations, operated at pH of 6 and temperature of 35oC. Information gained from these studies was encapsulated in a mathematical model to describe sulphate reduction in anaerobic treatment systems. This model was also validated using data generated from the experiments. The experimental study showed that · At low sulphate concentrations of about 250 mg.L-1 and COD concentration of 10,000 mg.L-1 in feed, relatively high percentage (up to 35 %) of produced sulphide was assimilated by biomass, while the rest of the sulphur was distributed as unconverted sulphate, dissolved sulphide, H2S gas and to a lesser extent as metallic sulphide precipitates. · The major electron donor for sulphate reduction in both the acidogenic and the methanogenic reactor was hydrogen gas. Therefore, sulphate reduction not only competed with hydrogen utilising methanogens for the available hydrogen, but also changed the distributions of organic acids, which were directly or indirectly influenced by the H2 partial pressure. · Sulphide concentrations of up to 6.5 mM free hydrogen sulphide) at pH of 7.2 was not inhibitory to methanogens · Sulphate reducing bacteria were able to grow even at a low hydraulic retention time of 1.2 hours in the well-mixed acidogenic reactor. It was estimated that the maximum specific growth rate (m) and half saturation constant (ks) of SRB was 1.31 h-1 and 3.8 mg S.L-1, respectively. These values were higher than those reported in literature. · Sulphate reduction was suppressed at high concentration of carbon in the feed. Accumulation of high concentration of volatile organic acids at high feed-carbon concentrations had little effect on sulphate reduction. However, extent of sulphate reduction had a negative correlation with total concentration of biomass. A non-competitive biomass inhibition function was proposed to model the correlation. From this fit it was estimated that a biomass concentration of about 3300 mg-COD.L-1 will completely inhibit sulphate reduction. · Sulphate reduction was affected by redox potential control and pH in the acidogenic reactor. High pH and low redox potential values were essential for sulphate reduction to proceed. At redox potential control of -300 mV, sulphate reduction was inhibited more at pH of 6 than it was at pH of 7. At redox potential values of -250 mV or higher, about 90 % inhibition of sulphate reduction was observed at both pH of 6 and 7. An existing model describing carbohydrate degradation was extended to include sulphate reduction processes. Despite experimentally observing that sulphate reduction only took place from hydrogen, all possible substrates for sulphate reducion was considered. These included: lactic acid, butyric acid, propionic acid, acetic acid and hydrogen. Kinetic parameters for sulphate reduction processes were obtained from documented literature. Inhibition of sulphate reduction by biomass and sulphur assimilation by biomass were included in the model. A new approach to calculate caustic consumption at given pH values was also included. A modification to hydrogen regulation function was also made to better predict product distributions as a function of gas-phase hydrogen concentration. Model validation was performed using data from dynamic experiments. Comparison to actual data was undertaken on several key variables in the acidogenic and methanogenic reactors such as: organic acid concentrations, gas compositions, gas production rates, sulphate and sulphide concentrations and caustic consumption rates. The model satisfactorily predicted sulphate and sulphide concentrations in both reactors. However, discrepancy between predicted and experimental data on organic carbon concentrations was seen, especially during organic carbon concentration step changes.

Lexical simplification : optimising the pipelineShardlow, Matthew January 2015 (has links)
Introduction: This thesis was submitted by Matthew Shardlow to the University of Manchester for the degree of Doctor of Philosophy (PhD) in the year 2015. Lexical simplification is the practice of automatically increasing the readability and understandability of a text by identifying problematic vocabulary and substituting easy to understand synonyms. This work describes the research undertaken during the course of a 4-year PhD. We have focused on the pipeline of operations which string together to produce lexical simplifications. We have identified key areas for research and allowed our results to influence the direction of our research. We have suggested new methods and ideas where appropriate. Objectives: We seek to further the field of lexical simplification as an assistive technology. Although the concept of fully-automated error-free lexical simplification is some way off, we seek to bring this dream closer to reality. Technology is ubiquitous in our information-based society. Ever-increasingly we consume news, correspondence and literature through an electronic device. E-reading gives us the opportunity to intervene when a text is too difficult. Simplification can act as an augmentative communication tool for those who find a text is above their reading level. Texts which would otherwise go unread would become accessible via simplification. Contributions: This PhD has focused on the lexical simplification pipeline. We have identified common sources of errors as well as the detrimental effects of these errors. We have looked at techniques to mitigate the errors at each stage of the pipeline. We have created the CW Corpus, a resource for evaluating the task of identifying complex words. We have also compared machine learning strategies for identifying complex words. We propose a new preprocessing step which yields a significant increase in identification performance. We have also tackled the related fields of word sense disambiguation and substitution generation. We evaluate the current state of the field and make recommendations for best practice in lexical simplification. Finally, we focus our attention on evaluating the effect of lexical simplification on the reading ability of people with aphasia. We find that in our small-scale preliminary study, lexical simplification has a nega- tive effect, causing reading time to increase. We evaluate this result and use it to motivate further work into lexical simplification for people with aphasia.

Estimativa do recurso contingente dos folhelhos oleígenos da Formação Tremembé, Bacia de Taubaté, na região de Tremembé-Pindamonhangaba, SP / Estimation of unconventional resource (oil shale) in Tremembé Formation, Taubaté basin, between Tremembé and Pindamonhangaba, SPLeonardo Simões Pimentel 29 June 2012 (has links)
Esta dissertação tem como objetivo apresentar uma estimativa preliminar do volume de recurso contingente não-convencionais de folhelhos oleígenos (oil shale) na Formação Tremembé através de métodos probabilísticos aplicados à informações compiladas de bibliografias existentes sobre a bacia. Como base para esta estimativa utilizou-se informações obtidas através de sísmica 2D, poços existentes na área e perfis geoquímicos. Através da interpretação dos mesmos foram gerados os valores de inputs para os parâmetros utilizados no cálculo, como: espessura econômica, densidade do minério e valor de Ensaio Fisher (Litros de óleo por tonelada de rocha). Para a análise foi construída uma planilha Excel no qual já descrito cada parâmetro do cálculo. Foi utilizado o software @Risk, da Palisade Inc., que é capaz de atribuir distribuições estatísticas a parâmetros utilizados no cálculo obtendo, a partir do método Monte Carlo, distribuições dos possíveis resultados. A metodologia apresentada se demonstra mais adequada ao caso em estudo que o método determinístico, devido a restrição e ausência da precisão dos dados o que aumentaria as incertezas e as chances de erro no cálculo do volume, podendo impossibilitar uma avaliação, no caso do segundo. A metodologia probabilística ao mesmo tempo em que permite uma avaliação preliminar na ausência de dados precisos, ela gera cenários probabilísticos de resultados, possibilitando a antecipação da tomada de decisões em um projeto, permitindo sua continuação ou abandono. / This paper aims to present a preliminary estimate of the volume of unconventional resource (oil shale) in Tremembé Formation, with probabilistic methods applied to previous studies in the basin. The estimate was based on 2D seismic, well and geochemical profiles. The interpretation of these values were generated for the input parameters used in the calculation, such as economic thickness, density and value of the Fisher Assay (liters of oil per tonne of rock). The analysis was done in Excel with a description of each parameter used. The plug-in software @ Risk (Palisade Inc.) was used, enabling statistical distributions and the use of Monte Carlo simulation in the estimate. The methodology proved to be more appropriate to the case study than to the deterministic method, due to restriction and lack of accurate data which would increase the uncertainties and the chances of error in calculating the volume, allowing a preliminary assessment generating distributions probabilistic results, enabling the anticipation of the decision-making process.
