This volume in the Fundamentals for the Water and Wastewater Main Operator series covers the basics of piping and valves in water and wastewater plants, including details on fittings, strainers, filters, traps and control systems. The book explains how pipes and valves are used to feed materials (e.g., chemicals) into influents and effluents and also siphon off unwanted liquid and gaseous byproduct. Also covered is how pipes are developed into systems and subsystems and coordinated into a plant-wide functioning unit.

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.

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 Pumping: This text provides information on pump fundamentals and applications, and introduces preventive maintenance and troubleshooting for hydraulic pumps. It explains both centrifugal and positive-displacement pumps. It also covers common problem areas and corrective actions, such as how to maintain packing and mechanical seals.

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.

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.

Machine Guarding Handbook is a must-have reading for safety engineers and managers in manufacturing and other industrial settings who need to incorporate an effective machine guarding safety program, meet OSHA requirements, and protect workers. It provides a basic overview of OSHA's requirements, making compliance easier to achieve, thus preventing the risk of worker injury or mutilation and reducing the occurrence of costly penalties and OSHA audits. This 106-page book explores and discusses the hazards of unguarded machines, common safeguarding methods, the safeguarding of machines and robots, the importance of guarding, the varying methods of machine guarding, training, inspection and maintenance, and safeguarding techniques. In addition, it provides both regulatory information and the material required to implement a viable machine guarding program. Special features include a sample lockout/tagout program, checklists, a machine-guarding case study, chapter summaries, and the complete OSHA Machine Guarding and Lockout/Tagout Standards.

FROM THE PREFACE This book brings together (in one text) all of the Occupational Safety and Health Administration's regulatory requirements for making safe and proper confined space entries. Because confined space entry is a complicated procedure-and a process that contains inherent risks-those concerned with safety in the work place are constantly concerned with how to reduce the risks associated with confined space entry, how to eliminate or decrease the hazards workers face in confined spaces, and how to prevent injuries and fatalities from occurring in confined spaces. But comprehensive materials on confined space entry are difficult to find. Surprisingly little material on the subject is commercially available. Confined Space Entry: A Guide to Compliance collects all of the associated requirements and regulations, including OSHA's Confined Space, Lockout/Tagout, Respiratory Protection Standards and Hot Work Permit requirements in this guidebook. These separate, specific safety standards and requirements have been combined and organized-as they should be, since each is married to the other-in a way that enables you (the user) to easily determine the critical relationship(s) between and among them-but more importantly, to teach you how to enter confined spaces safely-and how to provide workers with effective training for proper confined space entry. Written in user-friendly, jargon-free plain English, this guidebook provides you with clear sample programs to serve as models when you write your own programs. Workers have a growing need for more knowledge of the hazards of their work environments-and especially of confined spaces. To fulfill this imperative need, individuals and government must work together to better inform-and protect-these workers as they are exposed to a variety of complex and potentially life-threatening situations in confined spaces. The message this text delivers is simple: The better both workers and management understand the potential hazards and the implementation of measures to either eliminate or reduce the risks and hazards of confined space entry, the safer the workers and the facility-and the better the relationship between the operating facility, the workers, the community, and the regulators. As a result of no information, misinformation, no training, no supervision, little or no knowledge, confined space fatalities are real-they occur. They occur far too often.

About the Book Managing biosolids for reuse and not for disposal is the focus of this book. The emphasis is placed on environmental compliance where the goal is the processing of treated biosolids to the production of a waste product (biosolids ash) that has been discarded in the past and to demonstrate that this particular waste byproduct has some value. When biosolids ash is managed for reuse and is not disposed of in the traditional manner, all sides win, including the environment.
