Water and Wastewater Conveyance: Pumping, Hydraulics, Piping, and Valves provides fundamental, basic information on the conveyance of water and wastewater. Written in straight-forward and easy-to-understand language for professionals and non-professionals alike, it provides the techniques to assist water and wastewater operators to better understand basic pump operations and applications, maintenance regimens, and troubleshooting procedures. Addressing a multitude of water quality issues, it provides an introduction to water hydraulics, piping systems, tubes, hoses, and ancillaries as well as valves, and the maintenance requirements of each. It also discusses common operational problems and their appropriate corrective actions. Definitions of key terms and self-examination questions are provided at the end of each chapter.

Assessment of freshwater sediments can determine whether chemical concentrations are sufficient to cause adverse effects on aquatic organisms or organisms higher in the food chain, including humans. This book presents methods for assessing sediments and includes an integration of physical, chemical, and biological information. It examines the elements of quality assurance and control programs, considerations for the conduct of field surveys, screening-level analyses, chemical analyses, toxicity tests for assessing biological impacts, assessments of benthic invertebrate community structure, surveys of fish tumors and abnormalities, and data presentation and interpretation techniques.

This book presents a multidisciplinary approach to renewable energy, covering physical and engineering approaches and addressing economic, social, environmental, and policy issues. It surveys all of the principal renewable energy sources available and uses straightforward language with little emphasis placed on math and theoretical science. Instead, the emphasis is placed on the technical aspects and practical applications of renewable energy. This new edition is updated and adds information on the latest innovations related to all types of renewable energy sources and the related environmental implications.

Environmental professionals are often called upon to find solutions to environmental degradation problems or to lead the way in planning to prevent them. Because they come mainly from the environmental and science disciplines, most environmental professionals have limited training in the fundamentals of economics. This book is designed to provide those professionals not only with the basic principles of economics for foundational purposes but also the economic pros and cons to consider when making critical decisions on environmental issues.

This volume covers computations and applied math problems used in wastewater treatment operations. It explains calculations for flow, velocity, and pumping; preliminary and primary treatments; trickling filtration; rotating biological contactors; and chemical dosage. It also addresses various aspects of biosolids in wastewater. The text presents math operations that progressively advance to higher, more practical applications, including math operations knowledge expected of operators at the highest level of licensure. Readers working through the book systematically will acquire a definitive understanding of performing applied water calculations that are essential for a successful career in the water industry.

A critical aspect of sustainability associated with water and wastewater systems is to maintain and manage infrastructure in the most efficient and economical manner while complying with environmental regulations and keeping rates at acceptable levels. Given the high cost of fuel, our growing population, and the associated increase in energy needs, it is important to address energy use and future energy availability for the treatment of the water we drink and the water we pollute. Water & Wastewater Infrastructure: Energy Efficiency and Sustainability addresses these issues, detailing the processes that can assist facilities to become more energy efficient and providing guidance to ensure their sustainability.The text begins with brief descriptions of the water and wastewater treatment industries. It then describes some of the basics of energy and discusses what planning for a sustainable energy future in water and wastewater treatment plants entails. The author explores energy-saving options and provides case studies to demonstrate how some facilities have used equipment, technology, and operating strategies to save money and reduce their impact. The energy-efficient technologies include combined heat and power (CHP), gas turbines, microturbines, reciprocating engines, steam turbines, and fuel cells. The author also addresses biomass power and biogas.The section on sustainability and renewable energy covers hydropower, solar power, and wind power as well as energy conservation measures for treating wastewater. Nine appendices provide individual case studies that present evaluations of energy conservation measures, results, payback analysis, and conclusions. This book addresses the challenges faced by water and wastewater treatment facilities by examining how they can operate in ways that provide economic and environmental benefits, save money, reduce environmental impact, and lead to sustainability.

Part of the "Fundamentals for the Water and Wastewater Main Operator" series, this title covers the basics of piping and valves in water and wastewater plants, including details on fittings, strainers, traps and control systems. It also covers how pipes are developed into systems and subsystems and coordinated into a plant-wide functioning unit.

Maintenance operators that can understand and properly use blueprints and schematics have little difficulty in correctly interpreting and using plant unit process drawings. This guide covers basic principles of blueprint reading and deals with principles and applications of schematics and symbols.

Covers fundamental, intermediate, and advanced wastewater treatment operations in individual volumes. This title offers coverage of emerging contaminants and their associated treatment processes and additional coverage of wastewater reuse/ sustainability.
