About the book Throughout my forty-year career in paper recycling, the lack of understanding the total process synergism of the fiber decontamination process often left me unsettled. Research and development in their analytical approach were excellent in developing break-through components. Advancements in Pulping, Screening, Cleaning, Flotation and process Chemistry in the last twenty years ensured the viability and desirability of recycled fiber products throughout the world, save for some serious and unpredictable glitches. The total process is more than the sum of its parts. Individual modules through their operating parameters influence each other's performance and by extension the performance of the whole process. This interaction appears to be chaotic. It often results in unpredictable end-product quality variations. This book explores not only the function, nature and operating idiosyncrasies of unit operations, but also their constant inter-action in a synergistic way. The reader will experience both the analytical and the synthetic methods necessary for the design, optimization and assessment of a recycling process. Various system configurations as well as the basic mathematics of mass balance and module efficiency calculations are included in the final chapters. The book contains multiple diagrams, charts, tables and illustrations that compliment the text. To the intended reader, professional or student, may I conclude?
