B usiness and industry are increasingly identifying water scarcity as a business constraint and risk. By the year 2030, the World Economic Forum estimates that the global demand for freshwater will exceed supply by about 40%. The ever-increasing demand for freshwater is causing us to consider the potential outcomes, where water stressors start to inhibit our ability to meet the critical needs of our customers around the world. Yet the risk is not equitable across the globe. Each watershed is different. There are acute shortages in some places and not in others. We also find that universally water is underpriced, and the prices are inverse to the risk.

Our conversation is changing. We are reframing our discussion and vocabulary around water to reflect the challenges, the risk to business, and the true cost of the resource. We are finding ourselves at an inflection point. We have obtained the knowledge and sophistication to make the case for water strategies in our facilities that make good business sense, and enable growth in an environmentally sustainable and socially equitable manner. Implementing water strategies within plants needs to make good economic sense and be accomplished in a manner that allows the business a fundamental license to grow.

Our fourth edition of The Nalco Water Handbook opens up the discussion on water scarcity, stressors, and the business case for managing water. The content throughout the book will assist you in maintaining clean heat transfer surfaces as well as addressing water management needs through the lens of reduction, reuse between applications, and recycle. As you read through the book, look for the items that can become actionable in your facility and not just protect your assets, but that can help your water management strategies as well.

A s Nalco Water approaches its 90th year in business, it seems fitting to release the fourth edition of The Nalco Water Handbook at the same time. Our first book, Water: The Universal Solvent, was published in 1977 in observance of the companys 50th anniversary. Frank N. Kemmer, editor-in-chief and John McCallion, associate editor of that book, went on to produce the first two editions of The Nalco Water Handbook and firmly placed Nalco Water well down the road of knowledge sharing. We at Nalco Water continue to believe this is as important today, as it was when the first book was published.

Water as a resource is becoming increasingly scarce throughout much of the world. In this edition of the book, we have restructured the initial introductory chapters through the lens of water scarcity, stressors, and business risk. In addition, we have added supplementary content around water conservation in various processes where applicable. We have also strengthened the discussions around various industry processes, impurity removal with membrane technology and water safety for building water systems. Finally, we have added additional chapters in the industry section to broaden the scope of the discussion.
