20 Aug. 2022: Process Chemicals for Papermaking is an authoritative, up-to-date, practical and readable text that describes some of the most important technological strategies in the use of process chemicals to achieve efficient operation of paper mills, starting with freshwater treatment and ending with wastewater treatment.

Each chapter deals with a defined topic area, gives general background and descriptions of the key technological challenges, and describes how different additives can be used in a strategic manner to better achieve efficient and trouble-free operations.

This handbook is designed for intermediate- to advanced-level engineers in paper mills. It emphasizes papermaking process additives, which are often overlooked and focuses on the synergies of recent equipment developments and state-of-the-art advancements in papermaking chemistry.

Edited by Martin A. Hubbe, Ph.D. and Scott Rosencrance, Ph.D.
