Abstract:

The pulp and paper industry is facing more stringent regulations on the quality of effluent discharges to receiving waters, especially for bleached pulp mills. In most cases, these regulations concern mainly AOX concentrations, biotoxicity and COD level in the final discharges. An effective way to improve pollution balance would be to use ozone as an external treatment to meet environmental regulations. The first part of this work has consisted in the identification of the polluting steps in pulp and paper mill processes in terms of toxic effects. After identification, effluents streams that contribute the most to the global pollution of the mill were selected for ozone treatment. For bleaching effluents, the goal was to eliminate acute toxicity and chlorophenolics to increase biodegradability. Depending on the nature of the effluent, complete detoxification and an increase of biodegradability can be obtained with low ozone doses (0.5-1 kg/ADt of pulp). Ozone has also been applied on the final effluent discharges before and after biological treatment. In hardwood and softwood pulp and paper mill final discharges, the residual COD can be eliminated with a catalyzed ozone treatment. This treatment may allow a water quality sufficient for reutilisation which could lower water consumption of the pulp processes.

Abstract:

Abstract Blue mussels (Mytilus edulis) were caged at three sites situated at increasing distance from the point of discharge of a pulp and paper mill effluent from July to October 1998. Two additional cages were deployed: one inside and one at the mouth of the adjacent industrialized Pictou Harbour. After 90 d exposure, we measured growth, survival, haemocyte counts (HC), phagocytic activity (PA), lysosome retention (LR) and bacterial clearance (BC). There was a small but significant difference in growth between cages. Mussels closest to the mill effluent grew the most while those at the mouth of the harbour grew the least. Mussels from three cages showed similar difficulty in clearing bacteria; the cage inside the harbour, the cage nearest to the pulp mill effluent and the cage furthest from the pulp mill, receiving a mixture of both pulp mill and harbour effluents. The mussels from those cages also showed the highest heavy metal burdens and conversely, the cage showing the most rapid clearance, outside both effluents, also showed the lowest heavy metal burden. Mussels caged in the pulp mill effluent showed lower PA and LR and higher mortality during the bacterial clearance test than other mussels. These results suggest that immunological biomarkers might be a useful and more sensitive adjunct to endpoints presently being measured from caged bivalves in environmental effects monitoring (EEM) programs, and assessments of aquatic environmental quality.

Abstract:

The mutagenic properties of pulp and paper mill effluents were studied in three mills: bleached kraft mill with aerated lagoon treatment (Mill 1), bleached kraft mill with activated sludge treatment (Mill 2) and mechanical pulp/paper mill (Mill 3). Both treated and untreated effluents, process streams and molecular fractions were tested for mutagenicity (Ames test. Salmonella typhimurium TA100 and SCE sister chromatid exchange test, Chinese hamster ovary cells). To verify the potential environmental effects the mutagenic activity of concentrated recipient lake water (Mill 2) was also studied. The Ames mutagenicity of the bleached kraft mill effluent (BKME) originated from the first chlorination filtrate, SCE mutagenicity also occurred in the alkali extraction stage filtrate (Mill 1). No Ames mutagenicity was detected in the paper mill effluent, but it was SCE mutagenic. Activated sludge treatment of BKME removed both Ames and SCE mutagenicity, but the aerated lagoon treated BKME was still SCE mutagenic. No mutagenic activity was detected in the recipient water concentrates.

Abstract:

Field and laboratory measurements of the transport of the suspended sediment from the Athabasca River near Hinton, Alberta, Canada are described. The objective of these measurements was to examine the influence of pulp mill effluent entering the river from a nearby pulp mill on suspended sediment. The results of the field measurement showed that the effluent had significant impact on the transport of the sediment. Specifically, the effluent increased the deposition rates of the sediment and caused a substantial reduction of sediment concentrations in reaches downstream of the effluent outfall. The reduction in sediment concentrations and the concomitant sediment loads can only be attributed to the pulp mill effluent as there were no abrupt changes in the hydraulic characteristics of the river in the reach of interest. These observations were confirmed by laboratory experiments that were carried out using a rotating circular flume located at the National Water Research Institute in Burlington, Ontario, Canada. The findings of this study have implications for modelling suspended sediment transport in rivers receiving bleached pulp mill effluents.

Abstract:

Abstract Pulp and paper mill effluents have been reported to cause changes in reproductive indicators of fish in laboratory and field studies. These changes include reduced egg production and gonad size, and altered hormone levels and expression of secondary sex characteristics. We examined the performance of biotreatment plants for their potential in abating effects of pulp and paper mill effluents on fish reproduction under laboratory conditions. A bleached kraft mill effluent (BKME) treated in an aerated lagoon and a thermomechanical pulp mill effluent (TMPE) treated by aerobic sludge in a sequential batch reactor were selected for study. Mature fathead minnows (Pimephales promelas) were exposed to effluents before and after biotreatment under continuous renewal conditions for 21 days. Egg production was monitored daily, while morphometric parameters (length, weight, gonad size), secondary sexual characteristics, and steroid hormone and vitellogenin levels were measured at the end of the effluent exposure. The effluent from both mills before biotreatment impaired the reproductive capacity of minnows (egg production) at concentrations of 10 and 20% vol/vol, but not at 2% vol/vol. Exposure to biotreated effluents from both mills at concentrations of 2, 10, 20, and 40% vol/vol caused no significant differences in overall reproductive capacity of minnows as compared with controls. These results indicate that biotreatment can significantly improve the quality of a BKME and an effluent from a TMP mill with respect to the reproductive capacity of fish as determined in laboratory tests.

Abstract:

Abstract Fathead minnow (Pimephales promelas) lifecycle tests have been used to assess the effects of many North American pulp mill effluents. Fish are exposed under controlled laboratory conditions to final effluent, from the egg stage through hatching, juvenile stage and mature adult stage. Outlined here are methods for the lifecycle test (which takes from 4 to 5 months to complete) with sampling of juvenile fish at 1, 2 and 3 months of age, and sampling of mature adults after breeding. The results of most fathead minnow lifecycle studies have shown that pulp mill effluents cause metabolic and reproductive disruption (enlarged livers, reduced egg production, smaller gonads, decreased sex hormones and reduced secondary sex characteristics). Thus, the fathead minnow lifecycle assay is able to mimic the most commonly observed changes seen in wild fish exposed to pulp mill effluents. Sensitive indicators of reproductive effects in fathead minnows exposed for a lifecycle to pulp mill effluents include secondary sex characteristics, time to first reproduction and number of eggs laid. Egg production is often the most sensitive response to pulp mill effluents. Because of the length and cost of full lifecycle tests, a shortened assay using adult fish was developed as a screen for endocrine-disrupting compounds. This assay, the terminal reproduction test, has been used with success on a few pulp mill effluents. The assay exposes fathead minnow breeding pairs for three weeks to effluent, and compares egg production, sex characteristics and bioindicators of reproductive performance in pre-exposure versus post-exposure fish. For assessment of pulp mill effluents, it appears that the sensitivity of the shortened terminal reproductive fathead minnow assay may be improved by assessing bioindicators of reproductive performance (such as circulating levels of sex hormones, and circulating or hepatic vitellogenin) along with changes in secondary sex characteristics and egg production.

Abstract:

The aim of this study was to examine the stability and bioavailability of different phosphorus fractions of pulp and paper mill effluents in order to assess the environmental benefits of reducing their phosphorus discharges. Two types of effluent were studied: activated sludge treated bleached kraft mill effluent and activated sludge treated paper mill effluent. Phosphorus was characterized on the basis of its solubility and chemical reactivity. The stability of particulate phosphorus was studied in long-term (6-8 weeks) degradation tests. The bioavailability of different phosphorus fractions was measured by algal growth potential tests. In bleached kraft mill effluent (BKME) the proportion of dissolved phosphorus in relation to the total phosphorus was on an average 80%, and of this, approximately 80-90% was reactive phosphorus. During a 6-8 week incubation period some 60-70% of the particulate phosphorus in BKME was dissolved as soluble phosphorus, and most of it was of the reactive type. Approximately 90% of the dissolved phosphorus and 45% of the particulate phosphorus in BKME was biologically available phosphorus (BAP). Altogether some 80% of the total phosphorus in activated sludge treated BKME was available for algae either immediately or after inherent degradation. The percentages of dissolved and particulate phosphorus of paper mill effluent (PME) total phosphorus were of the same order of magnitude as those of BKME, but less than 20% of the dissolved phosphorus was of the reactive type. Approximately 50-60% of the particulate phosphorus in PME was dissolved in degradation tests, and 90% of it was biologically available.

Abstract:

Nitrogen concentrations of effluent before and after treatment plant in two mills have been measured during five days time in a bleached kraft pulp mill and in a newsprint mill. In effluents before treatment the concentration of inorganic nitrogen was low but in the effluent of kraft pulping process, the main part is inorganic nitrogen. In effluent after treatment the concentration of inorganic nitrogen is low. After activated sludge treatment plant the concentration of dissolved organic nitrogen is about 0.6 mg/l and nitrogen in suspended solids determines fluctuation of nitrogen content in treated effluent. There is no need for biological nitrogen removal processes if the addition of nitrogen in the treatment is correct.

Abstract:

Pulp and paper mill effluent induced phytotoxicity and genotoxicity in mung bean (Vigna radiata L.) and root tip cells of onion (Allium cepa L.) were investigated. Physicochemical characteristics such as electrical conductivity (EC), biological oxygen demand (BOD5), chemical oxygen demand (COD), and total phenols of the pulp and paper mill effluent were beyond the permissible limit specified for the discharge of effluent in inland water bodies. Compared to control plants, seedling exposed to 100% effluent concentration showed a reduction in root and shoot length and biomass by 65%, 67%, and 84%, respectively, after 5 days of treatment. A. cepa root tip cells exposed to effluent concentrations ranging from 25 to 100% v/v showed a significant decrease in mitotic index (MI) from 32 to 11% with respect to control root tip cells (69%) indicating effluent induced cytotoxicity. Further, the effluent induced DNA damage as evidenced by the presence of various chromosomal aberrations like stickiness, chromosome loss, anaphase bridge, c-mitosis, tripolar anaphase, vagrant chromosome, and telophase bridge and micronucleated and binucleated cell in A. cepa. Findings of the present study indicate that pulp and paper mill effluents may act as genotoxic and phytotoxic agents in plant model system.

This study examines the wastewater treatment system on BillerudKorsnäs integrated pulpand paper mill at Karlsborg, with focus on the effluent of suspended solids. Due to lowerregulatory limits for the emissions of suspended solids BillerudKorsnäs is looking forways to improve the efficiency of the wastewater treatment. Therefore, this study seeksto create a statistical model for the emissions of suspended solids and to find which factorsin the production, wastewater treatment and surrounding environment that affects theemissions. The purpose of the study is to extend the current understanding of the treatmentsystem to create a base for future decisions. The methods used for the modelling areElastic net regression and Random forest classifier, which were selected for the variableselection properties they provide. Unfortunately, the results show that the fitted modelscan only explain a small part of the variation of the emissions of suspended solids.The lack of fit in the models indicate that the current data is not sufficient to explain thevariation in the emissions of suspended solids. During the study deficiencies in the datacollection has been detected and improvements to overcome these deficiencies are proposedin the hope of creating more reliable data for the company and to create a betterbasis for future studies.<br>Denna studie undersöker avloppsvattenreningen på BillerudKorsnäs integrerade massaoch pappersbruket i Karlsborg, med fokus på utsläppen av suspenderade ämnen.

Abstract:

The photooxidation of a Thermo-Mechanical (TM) pulp and paper mill effluent with hydrogen peroxide $ rm(H sb2O sb2)$ was investigated at different experimental conditions by using a batch photochemical reactor operating at a dominant UV light wavelength of 253.7 nm. Photolysis of $ rm H sb2O sb2$ produces hydroxyl radicals ($ cdot$OH), which are very powerful oxidizing species. The effluent consisted of a "heat condensate" obtained from toxic vapors generated during various stages of the pulping process. Several operational parameters were varied and their effects on the process were observed and analyzed, in order to achieve its optimization. In addition, heterogeneous photocatalysts such as cupric oxide (CuO) were also investigated as a complement to the photooxidation process.<br>The main parameter used to determine the quality of the wastewater before and after photooxidation was the Chemical Oxygen Demand (COD), using a closed reflux standard procedure. COD values of the treated solution were determined at subsequent time intervals and used to draw curves illustrating the rate of oxidation of the wastewater. Other parameters, such as Dissolved Organic Carbon (DOC) and dissolved lignin concentration, were investigated towards the end of the research in order to obtain a more complete characterization of the quality of the wastewater after treatment.<br>The experimental data reveal that there is an optimal $ rm H sb2O sb2$ concentration that is best suited for the photooxidation of the effluent. Moreover, an increase in temperature accelerates the rate of elimination of COD. An increase in effluent concentration is detrimental to the speed of the process, since it causes an increase in its absorbance which can act as a barrier against UV light. The efficiency of the photooxidation process is not affected by variations in the initial pH of the wastewater. Cupric oxide (CuO), when exposed to UV light, efficiently catalyzes the production of OH radicals and is therefore very beneficial to the photooxidation process.

Abstract:

Resin and fatty acids (RFA) are predominantly components of coniferous trees having the natural function of protecting against microbial damage. These compounds are released from wood during the pulping process and a fraction reaches the wastewater treatment system. RFA are acutely toxic to aquatic organisms at concentrations on the order of parts per million, and their presence has been linked to toxicity outbreaks in receiving waters following process upsets. The chronic toxicity of resin and fatty acids in complex effluent matrices is poorly understood. Furthermore, the role of hydrophobic, pulp-derived solids as a removal pathway from wastewater streams has not been comprehensively studied. The objectives of this dissertation have been to quantify the relationship between resin and fatty acid concentration and chronic toxicity and to determine the role of partitioning in the removal of these compounds from pulp mill wastewater streams. Field and laboratory studies were conducted to measure toxicity using the Microtox™ whole effluent toxicity and Ceriodaphnia dubia 7-day, survival and reproduction bioassays. One resin acid in particular, dehydroabietic acid, was found to account for a significant fraction of final effluent chronic toxicity. Dissolved and sorbed RFA concentrations were quantified by solvent extraction, methyl ester derivatization, and GC-FID analysis. Partitioning to suspended solids was found to be a major removal pathway for the RFA from the effluent treatment system. A kinetic model for flotation was applied and compared to experimental data. Flotation was found to be effective at selectively removing RFA bound to pulp-derived solids from pulp mill and bleach plant sewers at moderate to high pH.

Os grânulos são agregados microbianos densos e compactos que possibilitam uma maior retenção de biomassa no reator biológico e uma elevada capacidade de sedimentação, favorecendo a remoção biológica de matéria orgânica, nutrientes, compostos tóxicos e clarificação final do efluente devido à estrutura e propriedade de sedimentação do lodo. Estes benefícios resultaram em um aumento do interesse de implantação do processo de tratamento com lodo aeróbio granular e a busca de maiores informações à respeito da formação, estabilidade e a influência dos parâmetros operacionais sobre a granulação. Assim, este trabalho apresenta uma revisão bibliográfica com a compilação das informações recentes sobre o lodo aeróbio granular incluindo a possibilidade de utilização dos grânulos aeróbios em biorreatores a membrana, em elevadas temperaturas e as aplicações em plantas de tratamento de larga escala. Foi realizada, ainda, a avaliação da adição de 100 mg.L-1 e 200mg.L-1 de cálcio na estabilidade, resistência mecânica e diâmetro dos grânulos formados em reatores em batelada sequencial alimentados com efluente de uma fábrica de polpa celulósica kraft. Os reatores apresentaram eficiências similares de remoção de matéria orgânica e o diâmetro médio dos grânulos foi de cerca de 11 mm em todos os reatores, embora os grânulos formados no reator que recebeu 100 mg.L-1 de Ca2+ apresentou velocidade de sedimentação 36% superior aos demais e maior resistência mecânica. A melhoria da granulação pode ser obtida ainda pela seleção de microrganismos que contribuem para a formação dos agregados. A produção de substâncias poliméricas extracelulares (SPE) pelas bactérias é um dos fatores que influencia a agregação celular, uma vez que as SPE agem como agente cimentante e atuam na adesão entre as células. A produção de SPE de dezenove isolados microbianos, obtidos de grânulos aeróbios formados no tratamento de efluente de fábrica de papel reciclado foi avaliada e seis isolados dos gêneros Staphylococcus, Agrobacterium, Enterobacter e Rhodococcus melhoraram a granulação biológica. A ausência destes isolados nos testes de co-agregação reduziu a relação entre proteínas e polissacarídeos (relação PN/PS) e diminuiu a formação de agregados.<br>Aerobic granular sludge wastewater treatment has many advantages over the conventional activated sludge process. The granules are dense and compact microbial aggregates that allow a higher biomass retention in the biological reactor and a high settling velocity, favoring the biological removal of organic matter, nutrients, toxic substances and improves wastewater clarification. Due to the sludge structure and settleability, these benefits have attracted considerable interest in the implementation of the aerobic granular sludge process and givenrise to the need for better understanding of the formation, stability and influence of the operational parameters on the granulation. Thus, this work was divided into three chapters. Chapter 1 presents a review of recent developments on aerobic granular sludge including the possibility of using aerobic granules in membrane bioreactors, at high temperatures and for a full-scale implementation. The addition of divalent cations in the reactors can enhance granulation and granule stability. In Chapter 2, the effect of the addition of 100 mg.L-1 and 200 mg.L- of calcium in the stability, mechanical strength and diameter of the granules formed in sequential batch reactors (SBR) fed with pulp mill effluent was evaluated. The reactors showed similar organic matter removal efficiencies and granule size was approximately 11 mm in all SBR, although the granules formed in the reactor with addition of 100 mg.L- of Ca2+ had a settling velocity 36% higher and greater mechanical resistance than the others. Granulation can also be enhanced by the selection of microorganisms that contribute to the aggregates formation. Bacterial extracellular polymeric substances (EPS) production is one factor that contributes to cell aggregation, since EPS acts as an intercellular cement that may reinforce cohesion inside the bacterial clusters. In Chapter 3, EPS production of nineteen microbial isolates obtained from aerobic granules formed in the recycled paper wastewater treatment was evaluated and six isolates of the genera Staphylococcus, Agrobacterium, Enterobacter and Rhodococcus contributed to biological granulation. The absence of these isolates in the co-aggregation tests reduced the protein-polysaccharide ratio (PN / PS ratio) and reduced the aggregates formation.

Abstract:

The influence of nitrogen (N) and phosphorus (P) limitation on pulp and paper mill activated sludge (AS) floc properties was studied using a bioreactor fed with synthetic Kraft mill effluent. The bioreactor and synthetic effluent were designed and shown to perform like the real mill system providing the AS, establishing the in vivo relevance of the results. Limitation of either N or P produced inadequate effluent biotreatment, shown by poor BOD5 and suspended solids removal, and by decreased biomass health, performance, and floc settling. Greatly enhanced poly-beta-hydroxybutyrate (PHB) (but not carbohydrate or extracellular polymeric substances [EPS]) synthesis was the common response of the floc microbial community to N limitation over many days. In contrast, P-limitation increased total carbohydrate and EPS, but not PHB.<br>N limitation, but not P limitation, caused the net floc surface charge to be much more negative, while P-limitation, but not N-limitation, increased the floc bound water content and surface hydrophobicity. Thus, in real pulp and paper mill AS systems, careful manipulation of N or P additions may be useful to optimize the key process of charged polymer-assisted AS dewatering.

Abstract:

Sustainability of resources such as energy, water and waste have become important drivers in our current economy. For large industries that are water and energy intensive like pulp and paper (P&P) mills, this is a specifically relevant issue. The large and heterogenous volumes of effluents in P&P mills make it a difficult task to properly treat before discharge. Anaerobic digestion is an efficient wastewater technology that cleans the effluent, reduces wasted sludge and simultaneously produces methane that can be further used as energy. The research work described in this thesis aims to enhance the methane production from the anaerobic digestion of different chemical P&P mill effluents. Through effluent characterization, variability of process parameters, promoting agents and the assessment of biochemical methane potential (BMP) tests, the benefits of three potential methods to enhance methane yields of wastewaters were evaluated. In addition, the conversion of chemical pulp fibers directly to methane was explored. The attained results described the different improvements that can be made to enhance methane production. Easily degradable effluents such as hydrolyzed filtrates and evaporator condensates contain high concentrations of sugars and acetic acid respectively, which could encourage an oversaturation of acids during acidogenesis. An inoculum to substrate ratio (ISR) of 2 proved to be the optimal in order to add the required buffering capacity to neutralize the pH and produce significantly high methane yields of up to 333 mLCH4/gVS. The high productivity of these effluents can be then considered for co-digestion with harder to treat effluents such as lignin-rich streams. Lignin clearly hinders methane production indicated by the negative linear correlation found between lignin content and methane yield. The co-digestion of lignin-rich effluent with evaporator condensates from neutral sulfite semi-chemical (NSSC) pulping proved to enhance the overall methane productivity of the mill´s wastewater treatment. Furthermore, the assessment of hydrotalcites (HT) addition indicated a contribution towards an increase in methane yield, faster production rates and a greater lignin removal. The poor performance of calcined HT suggests that the advantages of HT addition came from the layered sheet structure. Finally, besides establishing the methane potential in various P&P effluents, the examination of methane productivity of different pulp fibers and its products proved to be a promising new energy alternative to explore. Brown, oxygen delignified and bleached pulp gathered biodegradabilities of up to 90% and methane yields as high as 380 mLCH4/gVS. With the current changing bio-economy this last approach paves the way in exploring alternative and novel uses for chemical pulp mill products.<br>La sostenibilidad en la gestión de recursos como la energía, el agua y los residuos se ha convertido en un aspecto clave en nuestra economía actual. Para grandes industrias que consumen mucha agua y energía, como la industria de pulpa y papel (P&P) este es un tema especialmente relevante. Los grandes y heterogéneos volúmenes de efluentes que producen las fábricas de P&P hacen que su adecuado tratamiento sea una tarea difícil. La digestión anaerobia es una tecnología eficiente para el tratamiento de aguas residuales; que limpia el efluente, reduce el lodo producido y simultáneamente produce metano que puede usarse como fuente de energía. El objetivo del trabajo de investigación descrito en esta tesis es aumentar la producción de metano a partir de la digestión anaerobia de diferentes efluentes producidos en fábricas de pulpa. A través de la caracterización del efluente, determinación de parámetros del proceso, agentes promotores y la evaluación de pruebas de producción de metano bioquímico se evaluaron los beneficios de tres métodos potenciales para mejorar los rendimientos de metano de los efluentes. Asimismo, se exploró la conversión directa de fibras de pulpa química a metano. Los efluentes fácilmente degradables, como los filtrados hidrolizados y los condensados del evaporador, contienen altas concentraciones de azúcares y ácido acético, respectivamente, lo que podría provocar una sobresaturación de ácidos durante la acidogénesis. Se ha demostrado que una relación de inóculo a sustrato de 2 resulta óptima para aumentar la capacidad tampón del sistema y neutralizar el pH y producir rendimientos de metano significativamente altos, de hasta 333 mLCH4/gVS. La alta productividad de estos efluentes hace que se puedan considerar para la co-digestión con efluentes más difíciles de tratar, como las aguas ricas en lignina. Claramente la lignina obstaculiza la producción de metano, tal y como indica la correlación lineal negativa encontrada entre el contenido de lignina y el rendimiento de metano. La co-digestión del efluente rico en lignina con el condensado de evaporadores de pulpa semi-química de sulfito ha demostrado mejorar la productividad de metano en el tratamiento de aguas residuales de la planta. Además, la adición de hidrotalcitas (HT) como catatlizadores contribuye hacia un aumento en la producción de metano, tasas de producción más rápidas y una mayor eliminación de lignina. Con HT calcinadas se han obtenido rendimientos bajos, lo que sugiere que las ventajas de la adición de HT provienen de su estructura laminar. Finalmente, además de establecer el potencial de metano que existen en los efluentes de P&P, la evaluación de la productividad de metano de diferentes fibras de pulpa y sus productos ha demostrado ser una nueva alternativa energética para explorar. El uso de pulpa blanqueada, sin blanquear y deslignificada con oxígeno muestran biodegradabilidades de hasta 90% y rendimientos de metano de hasta 380 mLCH4/gVS. Con la cambiante bioeconomía actual, este último enfoque estimula la exploración de usos alternativos y novedosos para productos de plantas de pulpa química.

Abstract:

Researchers have linked resin and fatty acids (RFAs) to acute toxicity, especially in thermomechanical and chemithermomechanical pulp and paper mill effluents. Thus, the measurement of total RFAs may be a rapid, inexpensive alternative to standard methods of toxicity monitoring, such as 96-hour rainbow trout testing. Current procedures for the analysis of RFAs typically involve solvent extraction and concentration, derivatization, and analysis by GC, HPLC, or TLC. These procedures are far too expensive, complicated, and time-consuming for implementation at mill sites.<br>This thesis reports the development of a rapid, colourimetric assay based on the dye methylene blue (MB) for the quantification of resin and fatty acids in pulp and paper mill effluents. This MB assay uses the complexation of the cationic organic dye molecule to the carboxylic acid groups of RFAs to form a measurable chromophore. The electrically neutral, blue-coloured complexes are then extracted into a poorly polar organic solvent, dichloromethane. The measured absorbance at 655 nm is directly related to the total RFA concentration in the effluent sample.<br>The methylene blue assay is inexpensive and simple to use. It has a method detection limit of 0.589 mg/L total RFA. There are good correlations between the results obtained using the methylene blue assay and a well-established GC assay, and between RFA concentrations measured by the MB assay and acute toxicity measured by Microtox. The assay is sufficiently simple and rapid to be practical for routine in-mill monitoring.

Full text

Abstract:

Abstract In tall oil distillation, as in virtually all systems in pulp and paper mills, there is a long term trend to increasingly aggressive corrosion conditions. Factors contributing to this trend include increasing plant size, steps taken to comply with effluent regulation, and the ongoing effort to increase production efficiency. It has long been known that a 6Mo stainless steel or nickel-base alloy will resist the very aggressive conditions in the tall oil distillation column, but no such grade has been available for economical construction. The availability and favorable experience with a 6Mo austenitic stainless steel, S31254, in pulp bleaching service suggest potential savings in maintenance costs and in increased production efficiency. This paper characterizes S31254 and discusses field experience in selection of advanced stainless steels for tall oil distillation service.

Abstract:

Abstract Maintaining pulp and paper facilities with protective coatings requires special considerations due to conditions specific to the mill site and the coating application area. A systematic year by year plan will increase service life for structural components, equipment, concrete, and buildings. It will minimize those “crisis” repair/replacement projects that put a strain on your budget and can compromise structural integrity and safety. Proper planning, which includes condition assessment, surface preparation, and paint system development, is the first step to a successful project. This paper presents several case histories on mill coating problems and offers practical solutions to them.

Full text

Abstract:

Abstract Fluoropolymers are ubiquitous in the pulp and paper industry. Fluoropolymer-lined pumps, valves, pipes, tanks, scrubbers, and towers are encountered frequently in the pulp mill. Chemically resistant fluoropolymer filter fabrics are used in bleach plant washers and flue gas scrubbers. In the recovery cycle, fluoropolymer coatings and fluoroelastomers are used as gaskets and expansion joints in accumulators and heat exchangers. Fluoropolymer-containing paper machine fabrics, roll covers, and greases provide corrosion-free, clean and smooth performance. The array of fluorinated materials for different applications is detailed. New corrosion and caustic resistant filter fabrics, surfacing veils, paints and ductwork are presented.

Full text

Abstract:

The manufacture of pulp and paper involves the use of water in almost every unit process. Integrated mills (those having both pulp and paper making facilities) have historically been located along a large, readily available supply of fresh water. Unlike many other industries which use a majority of fresh water for cooling purposes, the paper industry uses a substantially larger fraction of water in the manufacturing process itself. Unit processes which require significant water use include wood handling, pulping, pulp screening and cleaning, pulp bleaching, chemical recovery, pulp storage and papermaking, and power generation. Figure 1 provides a schematic of water use in a hypothetical bleached kraft mill.

Abstract:

Abstract Protective coatings for structural steel in pulp and paper mills are often selected on the basis of intuition and performance in unrelated applications. Rarely are both qualitative and quantitative information available on steel coatings performance in the unique environment of the mill. This paper presents current results of practical experience and laboratory research on the use of hot dip galvanizing in pulp and paper environment. The combination of descriptive performance data and the predictive value of quantitative results demonstrates the viability of galvanizing in the pulp and paper industry.

Full text

Abstract:

This study investigates the feasibility of valorizing pulp and pulp sludge (PPS) into methane through anaerobic digestion (AD) with a focus on techno-economic analysis (TEA). Three scenarios are evaluated: (A) the base case, (B) sludge AD with alkaline pretreatment using green liquor dregs (GLD), and (C) co-digestion with nitrogen-rich feedstocks. The evaluation is applied to a common PPS, consisting of 70% primary sludge (PS) from the primary clarifier and 30% secondary sludge (SS) from biological treatments from a kraft mill. Theoretical methane potential (TMP) is determined using the Buswell equation. The study highlights the significance of co-digestion with nitrogen-rich feedstocks in enhancing the economic viability of the AD process for PPS, providing valuable insights for sustainable waste management and resource recovery in the pulp and paper industries.
