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. Electronics explains the fundamental structure and operation of the electronic hardware that underlies many automated processes in a treatment plant. It provides an introduction to electrical circuits, diodes, transistors, and transformers, which are explained in the context of device control.

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.

This new edition of a very successful standard reference is expanded and fully reworked. The book explains and quantifies the processes whereby streams cleanse themselves, reducing their pollutant load as a natural process. Mechanisms of purification in running waters have always been critical with regard to clearly identified pollution sources. This new edition explains the self-purifying function of streams and rivers in light of recent EPA rules on nonpoint pollutants and total maximum daily loads (TMDLs). It also covers basic concepts such as biological oxygen demand (BOD). Also new in this edition is an extended discussion of how streams originate and how they fit into the geomorphology of the earth and other water supply sources.Information is presented on aquatic life, including macroinvertebrates and their role as bioindicators of stream health. Chapter review tests and answers are included so that the readers can evaluate their mastery of the concepts presented. Stream Ecology and Self-Purification: An Introduction, 2nd Edition serves as a practical introduction to ecology combined with an explanation of how streams absorb and react to pollution. This text will prove valuable to water and wastewater plant operators, watershed managers, trainers, environmental students, water quality professionals, and will be an excellent preparation aid to wastewater/water operator licensing exams.
