Water Reuse Roadmap
Increasingly, our demands for water for both human activity and the environment, are pushed to the limits of naturally available water resources. Engineered water reuse systems can harness natural cycles to augment water demands, but the challenges, opportunities, and benefits of water reuse are broad and diverse. This book is an overview of all the opportunities and issues faced by water reuse projects. Developed to help water managers facilitate successful water reuse programs, from concept development through implementation and maintenance, the guidance in this book enables water managers to determine the social, technical and financial feasibility of water reuse options in their specific situation, initiate a water reuse program when appropriate, or expand an existing reuse program based on new approaches and opportunities for innovation. It begins with initial concept development; then describes stakeholder engagement, regulatory, risk assessment, and planning processes; and finishes with advice on financing, implementing, operating, and maintaining water reuse infrastructure.

Activated Sludge and Nutrient Removal (3rd Edition)
This extensively revised third edition of this book, MOP OM-9 reflects industry best practices and the latest advances. It is the primary reference for the operation of the activated sludge process. Expanded content includes an updated process control section with step-by-step examples for calculations, a new laboratory chapter with detailed directions for common process control tests, and an introduction to using modeling for process control. Operators are guided through selecting an appropriate sludge age, calculating wasting rates, optimizing return activated sludge flow, managing clarifier blankets, and setting DO and ORP set points. Advanced concepts in nutrient removal and biological process modeling are also addressed. Practice questions have been added to the end of each chapter to help the reader enhance their understanding of the material and retain information vital to solving performance problems and improving operations.

Financing and Charges for Wastewater Systems (4th Edition)
This 4th Edition of this book provides an overview of current industry practices that should be considered for financing and establishing rates and charges for wastewater collection and treatment systems. In addition, this Manual of Practice reflects and is responsive to changes in the industry over the last decade that have occasioned a heightened awareness about wastewater utility financial management and the equitable distribution of cost responsibilities across customer groups or classes. These changes, including tightening environmental regulation and replacement of aging infrastructure, have resulted in a pronounced increase in the cost of wastewater services. At the same time, the portion of costs paid through federal and state assistance programs have declined, challenging the affordability of this vital service. In this context, guidance on wastewater rate-setting practices, and particularly the distribution of costs across user groups, is of critical importance.

Desalination engineering. Operation and maintenance
\"A comprehensive, one-volume engineering reference from the Water Environment Federation and WateReuse Association on desalination plant operation and maintenance..Desalination Engineering: Operation and Maintenance provides a comprehensive one-volume reference on desalination for municipal water supply professionals. This authoritative guide covers key aspects of desalination plant operation, maintenance, and troubleshooting. The focus is on reverse osmosis membrane desalination, which at present is the most widely used technology for production of fresh drinking water from highly saline water sources. This Water Environment Federation and WateReuse Association guide covers state-of-the art operation, maintenance, and monitoring practices associated with each of the key desalination plant facilities--intakes, pretreatment technologies, reverse osmosis equipment, energy recovery, membrane systems, post-treatment processes, and solids handling.... Covers theoretical principles of desalination and their practical application.. Presents a step-by-step approach for operation, maintenance, and troubleshooting of desalination plant treatment components.. Discusses pre-treatment and reverse osmosis.. Each chapter contains case-study examples illustrating various technologies and their practical implementation.. Provides federal and state regulatory agencies with background on the monitoring requirements to determine and prevent potential environmental impacts associated with the discharges from desalination plants and to reduce the impact of their operations on the environment.. Uses International System of Units (SI) with US units in parenthesis where appropriate..\"-- Provided by publisher.
