The book "Water treatment and water-chemical regimes of thermal power plants and nuclear power plants" by B. A. Chizhya is an indispensable source of knowledge for all who are interested in energy, ecology and water treatment technologies. In today's world, where issues of ecology and efficient use of resources are becoming more relevant, this publication offers a deep and comprehensive analysis of water processes at thermal and nuclear power plants. In his book, Chizh addresses the most important aspects of water treatment, which are the basis for ensuring the reliable and safe operation of thermal power plants and NPPs. He examines in detail the chemical processes occurring in water systems and their impact on the efficiency of power plants. The reader will learn how to properly select and treat water to minimize corrosion and deposits that can significantly affect the operation of equipment. The book will be especially useful to engineers, energy professionals, students of technical universities and anyone who seeks to deepen their knowledge in the field of water technologies. Thanks to the available language and clear structure, even those who are just starting their way in this area will be able to easily assimilate the material presented. In. A. Chizh uses many examples and practical recommendations, which makes the book not only a theoretical manual, but also a practical guide. The topics raised in the book cover a wide range of issues from the basics of water treatment to the complex water-chemical regimes used in modern power plants. Chizh emphasizes the importance of water quality control and its impact on environmental safety. It also reviews modern methods of water systems analysis and monitoring, making the book relevant for professionals working with the latest technologies. The author’s style is distinguished by clarity and logical presentation . Chizh skillfully combines scientific data with practical examples, which allows the reader not only to understand the theory, but also to see how it is applied in practice. His previous works, such as “Energy Ecology” and “Wastewater Treatment Technologies”, were also highly appreciated among specialists and students, which confirms his status as an expert in this field. “Water treatment and water-chemical regimes of thermal power plants and nuclear power plants” is not just a textbook, but a real reference book for everyone who wants to understand the complex processes taking place at energy facilities. It will become an indispensable assistant for professionals seeking to improve the efficiency of their installations and reduce the negative impact on the environment. If you are looking for information about water treatment, water-chemical regimes, as well as modern technologies in the energy sector, this book is right for you. It will attract the attention of not only students and engineers, but also all those interested in sustainable development and environmental safety. Chizh creates a bridge between theory and practice, making his work particularly valuable in the rapidly changing world of energy technology. Do not miss the opportunity to expand your knowledge and deepen your understanding of the most important processes that are behind the work of thermal power plants and nuclear power plants .
