This is the only book series devoted to explaining the full range of specialized areas required of water and wastewater plant operators. Each volume is designed to give operators the basic knowledge of a subject needed for certification, licensure, and improved job performance. Checkpoints, self-tests and a final examination with questions based on actual operator certification exams provide a practical review. All books are clearly illustrated with key ideas and highlighted points throughout. Water Hydraulics: This volume is the first training book to explain water hydraulics in the context of treatment plants, presenting hydraulic theory and calculations in terms of the machinery and unit operations familiar to operators. It covers hydraulics as related to keeping water moving from one unit process to the next, including maintaining proper settling times and settling velocity, and providing lift to higher elevations.
