Abstract:
Macrophyte plants e.g. reed, cattails, bulrush, can be applied to sewage sludge utilisation. One of the first facilities of this type in the Gdansk region (Northern Poland) was established in Darzlubie in 1995 and primary sludge has been utilised in reed beds there. The objective of the undertaken research was evaluating the influence of sewage sludge storage on its chemical and biological properties. A total of 5.5 m thick layer of primary, anaerobically stabilised sludge (moisture 90-96%) was loaded to the reed bed during 6 years of operation. As a consequence of dewatering and biochemical transformation, the sludge layer decreased to 30 cm. Moisture, organic matter, total nitrogen and total phosphorus contents, as well as coli index, Clostridium perfringens index and the number of Ascaris lumbricoides ova were measured. Also the contents of heavy metals (Cu, Pb, Zn, Ni, Cr and Cd) were determined in sludge samples. The study showed that sludge storage in reed beds results in dewatering and partial stabilisation. In the reed lagoons in Swarzewo and Zambrow, dewatering of secondary sludges was investigated. The results of measurements of the quality of sludge and effluent from the reed lagoon in Zambrow are also presented.

Abstract:
A sludge lagoon has been adopted as a simple and cost effective method for dewatering of sludge. The processes occurring in a sludge lagoon include thickening, dewatering, storage and stabilization; all happening simultaneously. The objective of this study is to determine the dewatering and drying rates at pilot-scale which occur in a lagoon having different design configurations. Two types of sludge lagoons with different initial sludge depth (0.75 m and 0.375 m) were investigated to measure the drying behavior and drying efficiency. The first design is a sludge lagoon with a clay bottom where the dewatering mechanisms are decanting supernatant and evaporation. The second design is a sludge lagoon installed with a sand and underdrains system, where the dewatering mechanisms are filtration or draining and evaporation. Sludge drying kinetic models with high fitness were plotted to describe the sludge drying behavior. Drying of sludge in a sludge lagoon with a clay bottom can best be described by an exponential function. Whereas, drying of sludge in a sludge lagoon with sand and underdrains system followed a logarithmic function. A lagoon designed with sand and underdrains system and having shallower sludge depth was the most efficient. The reduction in volatile solids was lower than 4% during the study period. The drying process proceeded with an increase in dryness and decline in pH value.

Abstract:
Abstract Disposal of sewage sludge on agricultural or forest lands has been shown to be an economical means of sludge disposal which reduces the amount of waste going to landfills and returns nutrients to the soil. The heavy metal content of sludge generally depends on the composition of influents and on the treatment process. The present study considers the sludge chemical composition of 23 municipalities in southern Quebec and the heavy metal concentrations in their respective drinking water supplies. This study attempts to determine the main multielement relationships characterizing sludge composition, and to verify the occurrence of a possible link between chemical element concentration in sludge and in water supplies. The main phenomena influencing the chemical composition of municipal sewage sludge were modeled by using principal component analysis. The analysis shows that Cu concentration in sludges highly correlates with the organic nitrogen, and a series of metals (Cd-Co-Cr-Ni-Pb) are deposited independently of N and P. The activated sludge process removes a greater quantity of N than aerated lagoons, but heavy metals are generally more concentrated in aerated lagoons. The metal level found in water supplies slightly correlates with the metal content of sludge. Treatment plants showing metal contamination problems are found in regions with high natural geo-chemical levels of metals.

Abstract:
Vermicomposting is at suitable methods for stabilization and converting of sewage sludge into useful products. To investigate the effects of bulking material on vermicompost quality, an experiment was conducted in a factorial design with three replications. In this experiment, the final dried sludge in lagoons was mixed with bulking materials (woodchips, three leaves, and wheat straw) in four mixing proportion with swage sludge (0, 15, 30 and 45%, V/V). Chemical properties of bulking materials, sewage sludge, and produced vermicomposts were determined. Vermicomposts had relatively low pH and electrical conductivity (EC). The nutrients content of vermicompost, especially N, P, Fe, and Zn, were high. These properties showed its suitable quality for use in agriculture. Heavy metals concentrations of vermicomposts, except Zn, were lower than recommended values by EPA. Mixing of Bulking materials with sewage sludge decreased pH, N, Pb, Co, and Cd, but increased Ca, Mg, Fe, Cu, Mn, Zn, and Ni content of produced vermicomposts. In most cases, the concentrations of nutrients were higher in 30% mixing proportion. Therefore, 30% (v/v) mixing of bulking material with sewage sludge is recommended for vermicompost production.

Abstract:
Every day in the city of St. Petersburg there is formed more than 10,000 m3 of sewage sludge. The main mass of deposits is stored at the landfill for storing waste with an area of up to 150 hectares. Toxic substances and pathogens contained in sediments can penetrate into the environment stipulating the significant pollution of the environment. In the arsenal of technologists dealing with the problem of sewage sludge disposal, there are numerous approaches and solutions, for instance: drying sludge, incineration, composting, vermicomposting, eco-concrete fixation. However, tried everything methodological approaches have not found their applications because of the impossibility of decrease in toxicity due to the presence of substances in the resulting substance of 1st and 2nd classes of danger, having a translocation mechanism of transition in plants. And, nevertheless, the problem of sewage sludge cannot be solved by used approaches because of the high toxicity caused by the presence of substances of the 1st and 2nd hazard classes in the obtained substance, for which the translocation mechanism of environmental contamination is characteristic. The aim of our work is the substantiation of the hygienic safety of the utilization of products obtained by geotube technology from deposits at the Northern Station for aeration «Vodokanal-SPb» in road construction. As the object of research there was selected the complex of sludge lagoons of the Northern Station for aeration «Vodokanal-SPb» located in the village of Novosilky. Sanitary-chemical, toxicological, parasitological, bacteriological, radiological. It is possible to observe the binding of ionic forms of ecotoxicants, transition of them to a bound state, which provides for the environmental safety. Helminthological and bacteriological studies show the epidemic safety of the product obtained by geotubing. Geotube technology seems to be the most promising in the treatment of accumulated sludge beds on sewage sludge.

Abstract:
The province of Ontario is Canada's most populous province with over 8 million residents out of a total population of 27 million. The province has 512 sewage treatment plants of which 137 or 27% are lagoons. Improved environmental effluent quality standards since the introduction of the lagoons has resulted in many of these being unable to achieve proper effluent quality. Typical effluent quality requirements across the province require a minimum of secondary treatment, that is 15 mg/l of BOD and suspended solids and 1 mg/l of total phosphorus. The movement towards a clean environment has resulted in phosphorus levels as low as 0.3 mg/l TP and in an increasing number of cases, full nitrification year round. Because many of these lagoons serve small populations in the 100 - 3 000 population equivalents category, the cost of upgrading such lagoons to tertiary quality effluent is significant. Two approaches for upgrading conventional lagoon systems were evaluated. They are called the Sutton and New Hamburg processes after the towns in Ontario where they were first installed. The Sutton process consists of extended aeration plant, followed by polishing lagoons with waste sludge sent directly to the lagoons, while the New Hamburg process consists of conventional lagoons followed by intermittent sand filtration.

Abstract:
A facultative sewage lagoon in Inuvik, N.W.T. was studied in August (ice free) and November (ice covered) 1984. Emphasis was placed on the microbiological aspects and their relation to lagoon performance. Analyses performed included, pH, total alkalinity, total solids, suspended solids, volatile solids, COD and BOD5 determinations. The microbiological tests included total plate counts (20°C) and psychrotrophic counts (1°C). Results indicated that the Inuvik sewage lagoon system achieved removal efficiencies, ranging from 90% BOD5 removal in summer to about 80% in winter. The total bacterial count was found to decrease in the liquid of the primary cells in the winter, but the bacterial count in the secondary cell was similar under both winter and summer conditions. No significant difference existed in bacterial counts in the sludge samples between primary and secondary cells. The total bacterial number decreased by one order of magnitude in the winter in sludges from all cells. A shift from mesophilic to psychrotrophic bacteria occurred in the winter. The percentage of psychrotrophs increased from less than 1% to over 80% with the change in season. The role of psychrotrophs in lagoon performance is discussed.

Abstract:
Novel products based on peracetic acid (PAA) have recently been developed for the disinfection of sewage and sewage effluents. The efficacy of such products has been assessed under both laboratory and operational conditions. Comparative laboratory studies of the effects of peracetic acid, chlorine dioxide and chlorine on indicator bacteria in secondary sewage effluent have shown peracetic acid to be a viable alternative to these halogen biocides. In a trial carried out at two small rural works, PAA was dosed into secondary effluent from either an activated sludge plant or a percolating filter bed prior to tertiary lagoon treatment. LOW levels of PAA greatly enhanced the natural decline in coliform levels across the lagoon, enabling much lower concentrations of bacteria to be discharged into the receiving streams. In another trial, secondary effluent from an activated sludge plant was treated before discharge into a stream leading to the sea. Coliform concentrations were greatly reduced along the watercourse downstream from the plant.

Abstract:

The effects of in-basin storage of sludge on the iron, manganese, and TOC removal of water treatment plant (WTP) clarifiers and on the dewatering characteristics of sludge were examined. The use of chlorine dioxide as a preoxidant to retard observed detrimental effects was also investigated.

Sludge samples that were stored over a period of 120 days were found to release up to ten times the original supernatant concentration of iron and manganese from the sludge into the overlying supernatant liquor when sludge redox potential values decreased below +100 mV. Organic carbon also increased in the supernatant but to a lesser extent. Sludge dewatering characteristics as measured by specific resistance and capillary suction time were found to improve when sludge redox potential readings remained over 100 mV but varied greatly when readings were below this level.

Field monitoring and sampling of the clarifiers at Lee Hall WTP and Harwood's Mill WTP from April to July showed that the removal efficiencies of the clarifiers was not related to in-basin sludge storage. This conflicted with a later portion of the study and was thought to be due to the lack of standardized sampling techniques.

The final phase of the investigation dealt with the use of chlorine dioxide to retard the negative effects of in-basin storage of sludge. Sludge accumulation in clarifiers resulted in decreased iron and manganese removal efficiencies when chlorine dioxide was not used. Addition of chlorine dioxide improved the iron and manganese removal efficiencies of the clarifiers. Sludge dewatering characteristics were found to improve with the use of chlorine dioxide as a preoxidant.

Abstract:
Stocking herbivorous aquatic organisms in wastewater treatment ponds specifically to control phytoplankton biomass and reduce suspended solids can provide small, rural communities with inexpensive, secondary wastewater treatment. The capability of several native fish species and the freshwater mussel, Elliptio complanata, to reduce suspended solids and phytoplankton was compared in laboratory and field enclosure experiments. Fathead minnows (Pimephales promelas), gizzard shad (Dorosoma cepedianum), and the common carp (Cyprinus carpio) had either no effect, or significantly increased suspended solids levels. None of the fish species consistently reduced concentrations of typical wastewater algal taxa. The ineffectiveness of fish was attributed to numerous algal characteristics such as cell size, shape, relative abundance, resistance to digestion, and palatability. In contrast, E. complanata consistently and substantially reduced both suspended solids and algae concentrations in wastewater. Small-sized algae and suspended particles were either directly assimilated, or removed from suspension as pseudofeces, further promoting clarification. The proportion of suspended solids and algae concentrations removed per individual mussel declined with increasing densities of mussels. Declines in suspended solids and algae attributable to mussel filtration were best described by semilogarithmic regression equations. Mean filtration rate of E. complanata ranged from 53 ml/h/mussel for colonial blue-green algae, to 134 ml/h/mussel for smaller green algae. The results of this study suggest that freshwater mussels can effectively control suspended solids and algae in eutrophic environments.

Abstract:
Processos biológicos de tratamento de esgotos são largamente utilizados mundialmente e, apesar de serem eficientes na remoção de matéria orgânica, têm capacidades limitadas na remoção de poluentes orgânios emergentes, principalmente fármacos. Este trabalho avaliou a eficiência dos processos de tratamento de esgotos por lodos ativados com oxigênio puro, lagoas aeradas e reator anaeróbio de fluxo ascendente (RAFA) na remoção de seis fármacos selecionados - paracetamol, ibuprofeno, atenolol, sinvastatina, carbamazepina e clonazepam, com altos índices de utilização pela população. Para isto, foram analisadas amostras de esgoto bruto e de esgoto tratado oriundas de três estações de tratamento de esgotos em operação no Estado de São Paulo, sendo realizadas quatro campanhas de coleta, durante dois anos, em períodos hidrológicos de seca e chuva. A técnica analítica utilizada foi a cromatografia líquida de alta eficiência acoplada à espectrometria de massas (LC-MS/MS), através de método estabelecido e validado para a execução desta pesquisa. Ibuprofeno, sinvastatina e clonazepam não foram identificados em nenhuma das amostras analisadas. Atenolol, paracetamol e carbamazepina foram detectados em todas as estações estudadas, observando-se remoção e liberação deles durante todos os processos de tratamento. A estação que adota o processo por lagoas aeradas mostrou maior eficiência na remoção de paracetamol e atenolol, sendo que um elevado tempo de detenção hidráulica empregado nela parece ter influenciado positivamente na eficácia de remoção destas subtâncias. A estação que utiliza lodos ativados com oxigênio puro apresentou remoções inferiores e maiores taxas de liberação dos fármacos paracetamol e carbamazepina. Já a estação que adota RAFA apresentou discreta superioridade na remoção de carbamazepina, e eficiências intermediárias para paracetamol e atenolol. A carbamazepina mostrou resistência à degradaçào pelos processos avaliados, porém a desinfecção do efluente final, por cloração, aparentemente elevou a remoção deste composto.
Sewage biological treatment processes are the most used worldwide and, in general, they show organic matter removal high efficiency, however their pharmaceuticals removal capacity were quite limited. The aim of this study is verify the efficiency of sewage biological treatment processes per pure oxygen activated sludge, aerated basin and upflow anaerobic sludge blanket (UASB), in removal of six selected drugs acetaminophen, ibuprofen, atenolol, simvastatin, carbamazepine and clonazepam, most frequently used by population. For this purpose, it was analyzed raw sewage and treated sewage samples from three sewage treatment plants localized at Sao Paulo, Brazil, in four collection stages, during two years, at dry and wet periods. The analytical technique of choice was high performance liquid chromatography tandem mass spectrometry (LC-MS/MS), by developed and validated method for this study. Ibuprofen, simvastatin and clonazepam were not detected at any samples collected. Atenolol, acetaminophen and carbamazepine were identified at all plants investigated, with removal and production during all treatment processes here considered. Aerated basin plant was most efficient in acetaminophen and atenolol removal, and a high hydraulic detention time seem be better to remove these compounds. Pure oxygen activated sludge plant showed lower removal rates and higher production of acetaminophen and carbamazepine. Already the UASB plant revealed a little superiority in carbamazepine removal, and intermediary efficacy to acetaminophen and atenolol removal. Carbamazepine showed persistence in treatment processes evaluated, however final effluent disinfection, with chlorination, apparently raised this compound removal.

Mestrado em Sistemas Energéticos Sustentáveis
A brief review of the paper pulp production process in order to understand the origin of the sewage sludge was performed. Then a general revision of the current treatment options for this type of waste was addressed. The thermal treatment by combustion was focused and a review of the state of the art of this process was performed. The high moisture content of sludge was identified as a major concern. Thus a revision of the state of the art regarding thermal drying of sewage sludge was performed. The drying behavior of sewage sludge from the pulp and paper industry was evaluated by experiment in a drying tunnel. Strong shrinkage, cracks and a weak crust phenomenon were identified. A drying kinetic model was developed by the use of Artificial Neural Networks achieving a high Pearson correlation coefficient in the validation tests. Additionally a theoretical assessment of the co-combustion process was performed having into account a 50 MWth combustion facility. The inclusion of different portions of sewage sludge in a fuel mixture and the influence of the sludge moisture content was studied. It was found that burning sewage sludge with more than 50 wt% moisture content is not possible. Furthermore the inclusion of sewage sludge in a biomass fuel mixture causes an increase in the fuel consumption, solids production and heat losses in the flue gas. Based on general thermodynamic considerations the thermal power of a sludge dryer was calculated. The use of waste heat to supply the energy needs of the drying process was addressed by the waste heat availability estimation as sensible heat and latent heat at the stack of the facility. A set of combustion experiments were done in a pilot scale bubbling fluidized bed combustor to assess the combustion efficiency by monitoring the CO2, CO, H2O and O2 levels in conjunction with the temperature profile along the reactor height. Two different types of fuel samples were prepared. One composed by 100 wt% sewage sludge (fuel sample 1) and other composed by 50 wt% sewage sludge and 50 wt% residual forest biomass (particle size <1mm) (fuel sample 2). Low CO levels were onserved especially for the fuel sample 2 which indicates a very efficient combustion process. The CO emission level established by the Portuguese law for this type of reactor was never exceeded under typical operating conditions. The temperature profile along the reactor confirms that the combustion of the fuel samples prepared occurs mainly in the freeboard zone. It was not observed agglomeration problems and the fluidization conditions were kept constant during all the experimental tests. After the combustion experiments a considerable ashes quantity were found and its particle size distribution was estimated.
Foi realizada uma revisão sucinta do processo de produção de pasta de papel, a fim de compreender a origem da lama biológica. Uma revisão geral das opções atuais de tratamento para este tipo de resíduo foi abordada. O tratamento térmico por combustão foi focalizado e uma avaliação do estado da arte deste processo foi realizada. Foi verificado que o elevado teor de humidade da lama representa uma grande preocupação. Por tanto, realizou-se uma revisão do estado da arte em relação à secagem térmica das lamas. O comportamento da lama secundaria da indústria de pasta e papel foi estudado experimentalmente em um túnel de secagem. Foram observados os fenómenos de encolhimento e rachaduras além do fenomeno de crosta, embora este último não seja muito pronunciado. Foi desenvolvido um modelo de cinética de secagem com recurso ao uso de Redes Neurais Artificiais, sendo observado um elevado coeficiente de correlação nas experiências de validação. Foi realizada uma análise teórica ao processo de co-combustão de lama com biomassa florestal numa instalação de combustão de 50MWth. Estudou-se a inclusão de diferentes fracções de lama numa mistura de combustível contendo biomassa florestal, assim como também a influência do teor de humidade da lama. Verificou-se que a combustão de lamas biológicas com mais do que 50 wt% em teor de humidade não é possível. Além disso, a inclusão destas lamas na mistura de combustível provoca um aumento do consumo de combustível na instalação, da produção de sólidos e das perdas de calor no efluente gasoso da instalação. Com base em considerações termodinâmicas foi determinada a potência térmica de um secador de lamas. A utilização do calor residual para suprir as necessidades energéticas do processo de secagem foi abordada a través da estimativa da disponibilidade de calor residual na forma de calor sensível e calor latente no efluente gasoso da instalação de combustão. Foi realizado um conjunto de experiências de combustão de lamas e sua mistura com biomassa florestal num reactor de leito fluidizado borbulhante á escala piloto para avaliar a eficiência de combustão através da concentração de CO2, CO, O2 e H2O, em conjunto com o perfil de temperaturas ao longo do reactor. Foram utilizados dois tipos diferentes de amostras de combustível, uma composta por 100 wt% de lama biológica (combustível 1), e outra composta por 50 wt% de lama biológica e 50 wt% de biomassa florestal residual (tamanho de partícula <1mm) (combustível 2). Foram observados baixos níveis de CO no efluente gasoso, emparticular para a amostra de combustível 2, o qual indica um processo de combustão muito eficiente. Para condições de operação (temperatura e estequimetria) típicas, verificou-se que o limite de emissão de CO estabelecido pela lei Portuguesa para este tipo de fornalhas não foi excedido. O perfil de temperatura ao longo do reactor confirma que a combustão das amostras de combustível preparadas ocorre principalmente na zona do freeboard. Não foram verificados problemas de aglomeração e as condições de fluidização foram mantidas constantes durante todos os ensaios experimentais. Após os ensaios de combustão foi observada uma quantidade considerável de cinzas na fornalha, tendo sido avaliada a sua distribuição granulométrica.

Abstract:
This paper presents the economic optimization of indirect sewage sludge heat dryer for sewage sludge incineration plants. The objective function based on two-phase heat transfer, and economic relations is provided to demonstrate the optimum size for the minimum investment cost. De-watered sludge is fed into the dryer with a mass flow rate of 165 tons per day and consists of 27% dry matter. After the sludge drying process, the dryness of sludge increases up to 40%. In the indirect sludge dryer unit, thermal oil is used to heat the dryer wall and to prevent heat loss. Thermal oil is circulated in a closed cycle and gathered into an oil tank. Total cost of the sludge dryer unit changes proportional to the dryer area. The optimum dryer area is found as 32.54 m2. The corresponding minimum cost is found as $35,700.

Abstract:
A series of tests have been done in a pilot scale air blown gasifier, to assess the performance of sewage sludge pellets and sewage sludge pellet/coal mixtures. The aim has been to compare the performances with that achieved with coal alone and to assess the suitability of the sewage containing fuel as a candidate fuel for the Air Blown Gasification Cycle (ABGC). The co-gasification of sewage sludge with coal raised both the CV of the fuel gas and the fuel conversion compared with values achieved with coal alone. The mixtures were operated under very similar conditions to those needed with coal and no adverse operational problems were encountered. A lower fluidising velocity was needed with the neat pellets to enable a stable bed height to be achieved. However, the conversion of the pellets to gas was very high and the fuel gas CV was higher than that achieved during the co-gasification tests. Overall, the results suggest that sewage based materials are suitable for use in the ABGC and that their use can improve the process performance.
