From Newcomers to Non-Specialist Business Professionals! 'Illustrated Immediate Impact: Water Treatment Mechanisms and Business You Can Fully Understand in One Book' to Be Released on April 27, Offering the Fastest Way to Grasp the Overall Picture of the Water Treatment Business

■ Background of Publication: From Newcomers to Non-Specialists, Why is an 'Overall Picture of Water Treatment' Needed Now?

'Water treatment technology' underpins Japan's social infrastructure, manufacturing industries, and cutting-edge semiconductor industries. However, its mechanisms are extremely complex and diverse, often regarded as the domain of 'tacit knowledge' held by experienced on-site engineers.

Currently, 'technical knowledge transfer' due to generational change is an urgent issue in the industry. For new employees and young staff assigned to the field, fragmented knowledge makes it difficult to grasp the overall picture of operations, leading to slow growth. Furthermore, with the increasing interest in water issues in recent years, opportunities for non-specialist business professionals such as sales, back-office, and management planning to engage in the water treatment business have rapidly increased. However, the gap in specialized knowledge hinders smooth communication.

In today's era of widespread generative AI, AI can instantly answer unfamiliar terms. However, without a comprehensive 'overall perspective' to view the complex system of water treatment, it is impossible to judge the correctness of AI's answers, leading to the risk of critical misinformation. This book was written to enable newcomers to water treatment and non-specialist business professionals to acquire a 'common language' in the shortest possible time, allowing them to ask 'appropriate questions' to on-site experts and AI.

■ Features of This Book: Deciphering Technology through 'Business' and 'Illustrations'

Utilizing abundant illustrations unique to Gihyo Co., Ltd.'s 'Illustrated Immediate Impact' series, this book thoroughly eliminates mathematical formulas and difficult theories that beginners and non-specialists often find frustrating.
