DOWNLOAD EBOOKPulp 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 EBOOKImplementing Cleaner Production in the pulp and paper industry The large—and still growing—pulp and paper industry is a capital- and resource-intensive industry that contributes to many environmental problems, including global warming, human toxicity, ecotoxicity, photochemical oxidation, acidification, nutrification, and solid wastes. This important reference for professionals in the pulp and paper industry details how to improve manufacturing processes that not only cut down on the emission of pollutants but also increase productivity and decrease costs. Environmentally Friendly Production of Pulp and Paper guides professionals in the pulp and paper industry to implement the internationally recognized process of Cleaner Production (CP). It provides updated information on CP measures in: Raw material storage and preparation Pulping processes (Kraft, Sulphite, and Mechanical) Bleaching, recovery, and papermaking Emission treatment and recycled fiber processing In addition, the book includes a discussion on recent cleaner technologies and their implementation status and benefits in the pulp and paper industry. Covering every aspect of pulping and papermaking essential to the subject of reducing pollution, this is a must-have for paper and bioprocess engineers, environmental engineers, and corporations in the forest products industry.

DOWNLOAD EBOOKAlthough the title of this book is Paper Chemistry, it should be considered as a text about the chemistry of the formation of paper from aqueous suspensions of fibre and other additives, rather than as a book about the chemistry of the raw material itself. It is the subject of what papermakers call wet-end chemistry. There are many other excellent texts on the chemistry of cellulose and apart from one chapter on the accessibility of cellulose, the subject is not addressed here. Neither does the book deal with the chemistry of pulp preparation (from wood, from other plant sources or from recycled fibres), for there are also many excellent texts on this subject. The first edition of this book was a great success and soon became established as one of the Bibles of the industry. Its achievement then was to collect the considerable advances in understanding which had been made in the chemistry of papermaking in previous years, and provide, for the first time, a sound physico chemical basis of the subject. This new edition has been thoroughly updated with much new material added. The formation of paper is a continuous filtration process in which cellulosic fibres are formed into a network which is then pressed and dried. The important chemistry involved in this process is firstly the retention of col loidal material during filtration and secondly the modification of fibre and sheet properties so as to widen the scope for the use of paper and board products.

DOWNLOAD EBOOKWith the exception of a slight hiccup during the height of the recent environmental movement (during the early 1990s), when for a year or two consumers were prepared to pay a price premium for lower quality recycled paper than for the virgin product, the inexorable improvement in the quality demanded of paper products continues. This demand for quality covers not only the aesthetics ofthe product but also its performance. Moreover, it is becoming increasingly the case that papers designed for a particular use must, as it were incidentally, also perform well in alternative applications. An example is that of office and printing papers, which are expected to perform as well in copier machines as in all the various forms of impact and non-impact printers. But even greater demands are made in other product areas, where board designed for dry foods can also be expected to protect moist and fatty materials and be made of 100% recycled fibre. The need to isolate foodstuffs from some of the contaminants that can affect recycled board is a· serious challenge. Thus, papermakers are constantly striving to meet a broadening spectrum of demands on their products; often while accepting declining quality of raw materials. The product design philosophy that has arisen in response to this is increasingly to isolate the bulk of a paper from its uses: to engineer the needed performance characteristics into the paper surfaces while more or less ignoring what happens inside.

DOWNLOAD EBOOKThis book provides the most up-to-date and comprehensive information on the state-of-the-art techniques and aspects involved in environment-friendly pulping technologies. Traditional chemical and semi-chemical pulping processes are not environmentally friendly. Therefore, it has become important to look for alternative approaches to mitigate wastewater emissions in the paper industry, by making more stringent regulations to improve environmental conservation. In response to this problem, new raw materials need to be explored to replace traditional choices and also new pulping processes need to be developed based on less polluting, more easily recovered reagents. This book presents new and emerging deep eutectic solvents for lignocellulosic biomass pretreatment, and discusses the effects of deep eutectic solvents on biomass pretreatment and the production of value-added products. It also introduces biotechnological methods of pulping. Biotechnological processes help to make manufacturing processes cleaner and more efficient by reducing toxic chemical pollution and greenhouse gas emissions. Given its scope, this book is of interest to applied chemists, foresters, chemical engineers, wood scientists, along with engineers and researchers involved in the pulp and paper industry as a valuable reference.
