Similarly without water, many of the industries cannot exist, as water is used in multifarious ways in industries. Water is the raw material, water is the ingredient, water is the medium of reaction and water is the conveying medium. Besides, water is used to generate steam and it is the major cooling agent. Without water, washing operations cannot be carried out. Needless to say that each process requires a specific water quality. While every industry is keen on the availability and abundance of water, it is a sad fact that not much importance is bestowed upon the quality of water. Adherence to the quality requirements of water would result in a better product, protection of equipment, increased efficiency and avoidance of losses. Even though the industry in general is very interested to know the quality requirements, there is a dearth of literature and even the available literature is scattered. The intention in writing this book is to provide comprehensive information on the quality requirements of water for each industrial use in a single volume. Almost all the major wet processing industries and quality requirements of water for such industrial processes are described in this book in detail.For easy understanding this book is divided into five parts, namely, 1) Introduction, 2) Impurities present in Water and their Effects on Industrial Uses, 3) Industrial Waters and their Quality Requirements, 4) Drinking and Irrigation water and 5) Impurities present in Water and their Effects on Water Treatment Systems. Every effort is made to provide all the possible information through these sections. Chapters are arranged in alphabetical order for easy access to the required chapter.My hope is that this book will fill that long felt need for the availability of a one volume scientific discussion, hoped to be a boon to all the industries, work managers, plant managers, water treatment personnel, chemists, and water treatment consultants, firms engaged in water treatment programs etc. This book will also serve as a ready reference to students of Industrial Engineering, Chemical Engineering, Industrial Chemistry, Applied chemistry, and to various other faculties of Colleges and Universities.
