Book Synopsis Anaerobic digestion in the kraft pulp and paper industry by : Eva-Maria Ekstrand
Download or read book Anaerobic digestion in the kraft pulp and paper industry written by Eva-Maria Ekstrand and published by Linköping University Electronic Press. This book was released on 2019-05-07 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution. Kraft pulping makes up 80% of the world production of virgin wood pulp, thus, the wastewaters from this sector represent a large unused potential for methane production. There are three main types of substrates available for AD at pulp and paper mills, the wastewaters, the primary sludge/fibre sludge, and the waste activated sludge. AD treatment of these streams has been associated with several challenges, such as the presence of inhibiting compounds or low degradability during AD. The aim of this thesis was to experimentally address these challenges and potentials, focusing on wastes from kraft mills. Methane potential batch tests showed that many wastewater streams still posed challenges to AD, but the alkaline elemental chlorine-free bleaching stream and the condensate effluents had good methane potentials. Further, the methane potential of kraft mill fibre sludge was high, and co-digestion of kraft mill fibre sludge and waste activated sludge was feasible in stirred tank reactors with sludge recirculation. By increasing the organic loading in a pilot-scale activated sludge facility and thereby lowering the sludge age, the degradability of the waste activated sludge was improved. The higher wastewater treatment capacity achieved by this method provides an opportunity for the mills to increase their pulp and paper production. Further, by dewatering the digestate after AD and returning the liquid to the activated sludge treatment, costs for nutrient supplementation can be reduced. In conclusion, the thesis shows that AD of wastes from the kraft pulp and paper industry was feasible and carried many benefits regarding the generation of methane as a renewable energy carrier, improved wastewater treatment and reduced costs. Different strategies on how AD may be implemented in the kraft pulp and paper industry were formulated and discussed. Produktionen av pappers- och massa genererar stora mängder avloppsvatten, vilket ställer höga krav på en effektiv vattenrening. Därtill har skärpta regler för utsläpp till vatten och luft tillsammans med en ökad efterfrågan på användning av förnyelsebar energi ytterligare ökat trycket på vattenreningen inom pappers-och massaindustrin, där anaerob nedbrytning med metanproduktion som följd skulle kunna utgöra en lösning. Produktionen av sulfatmassa (en kemiskt kokad pappersmassa) utgör 80% av den globala nyproduktionen av massa, vilket innebär att avloppsvatten från denna sektor representerar en stor outnyttjad potential för metanproduktion. Det finns huvudsakligen tre typer av substrat tillgängliga för rötning vid pappers- och massabruk, avloppsvatten, primärslam/fiberslam, och aktivt slam/överskottsslam. Flera utmaningar är kopplade till anaerob nedbrytning av dess strömmar, såsom förekomst av inhiberande ämnen eller låg nedbrytbarhet. Målet med avhandlingen var att bemöta dessa utmaningar, med ett särskilt fokus på behandling av avloppsströmmar från sulfatbruk. Metanpotentialtester visade att många av avloppsvattnen fortfarande var svåra att behandla med anaerob nedbrytning, men att alkaliska blekeriströmmar och kondensatströmmar vid sulfatbruk visade lovande metanpotentialer. Massafiber från sulfatoch sulfitbruk uppvisade höga metanpotentialer, och en stabil kontinuerlig samrötning av fiberslam och aktivt slam från sulfatbruk uppnåddes vid hög organisk belastning och låg hydraulisk uppehållstid i omrörda tankreaktorer med slamåterföring. Resultaten visade vidare att den låga nedbrytbarheten hos aktivt slam kunde bemötas genom att sänka slamåldern i den luftade anläggningen, med högre metanpotential i slammet som följd. Via denna metodik erhålles en högre vattenreningskapacitet, vilket innebär att bruken kan öka sin produktion av papper och massa. Dessutom kan rötresten avvattnas och den kvarvarande vätskan återföras till den luftade anläggningen för att minska behovet av näringstillsatser. Sammanfattningsvis visar avhandlingen att anaerob nedbrytning av avloppsströmmar från sulfatbruk var fullt möjlig och innebar många fördelar, i form av metanproduktion, förbättrad kapacitet för vattenrening och reducerade kostnader jämfört med dagens teknik. Olika möjligheter för implementering av anaerob teknik vid sulfatbruk har också formulerats och diskuterats.

Book excerpt: Pulp and Paper Industry: Emerging Waste Water Treatment Technologies is the first book which comprehensively reviews this topic. Over the past decade, pulp and paper companies have continued to focus on minimizing fresh water use and effluent discharges as part of their move towards sustainable operating practices. Three stages—basic conservation, water reuse and water recycling—provide a systematic approach to water resource management. Implementing these stages requires increased financial investment and better utilization of water resources. The ultimate goal for pulp and paper companies is to have effluent-free factories with no negative environmental impact. The traditional water treatment technologies that are used in paper mills are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. This book discusses various measures being adopted by the pulp and paper industry to reduce water consumption and treatment techniques to treat wastewater to recover it for reuse. The book also examines the emerging technologies for treatment of effluents and presents examples of full-scale installations. Provides thorough and in-depth coverage of advanced treatment technologies which will benefit the industry personnel, pulp manufacturers, researchers and advanced students Presents new treatment strategies to improve water reuse and fulfill the legislation in force regarding wastewater discharge Presents viable solutions for pulp and paper manufacturers in terms of wastewater treatment Presents examples of full-scale installations to help motivate mill personnel to incorporate new technologies

Download or read book Biofuel Production Technologies: Critical Analysis for Sustainability written by Neha Srivastava and published by Springer Nature. This book was released on 2020-03-23 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production and utilization of sustainable energy toward maintaining a clean environment is a major challenge. At the same time, the continued depletion of fossil fuels and the global dependency on non-renewable fuels is a chief concern. Moreover, the long-term economic and environmental issues associated with the high utilization of fossil fuel, such as global warming, are also important, particularly in the context of the predicted increase in the global population to around 5 billion by 2050. In recent years, researchers have been investigating alternative, renewable fuels to replace fossil fuels. Of the various options, biofuels are especially attractive due to their low production costs and the fact that they are pollution free. Also known as transportation fuels, their energy is derived from biological resources or through the biological processes. Biofuels such as biohydrogen, biomethane, biogas, ethanol and butanol offer a number of advantages and can be economically produced from cellulosic biomass. As such, they can play a vital role in sustainably meeting future energy demands. Biofuels have the potential to become a global primary energy source, offering significant reductions in greenhouse gas emissions as well as opportunities to increase economic and social development in rural communities and reduce the problems associated with waste disposal. However, low yields and lack of process technology are some of the aspects that need to be addressed. This book offers an overview of existing biofuels and the technologies to solve the problems associated with their practical implementation. Evaluating the biofuel options and discussing the opportunities and risks in relation to resources, technologies, practices, markets and policy, it provides insights into the development of economically viable bioenergy industries.
