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
