Описание: The effects of air and vacuum pockets present in a liquid piping system can negatively impact not only pump, meter, and control valve operation but can also be responsible for pipeline breaks and collapses. Choosing and installing the correct air valve is critical to all liquid piping systems.

This manual of practice provides essential information for selecting, sizing, locating, and installing air valves in water, wastewater and reclaimed water pipeline systems. This revised second edition includes information pertaining to wastewater applications including scouring velocities for larger piping systems, and information on an inflow preventer device installed to protect from malicious tampering, freeze and flood, and to prevent the entry of contaminated water into the potable water distribution system.

Operators, technicians, and engineers will use this manual to understand the design, use, application and maintenance of air valves.

The air valve types listed in both ANSI/AWWA Standard C512, Air Release Valves, Air/Vacuum, and Combination Air Valves for Water and Wastewater Service and ANSI/AWWA C514, Air Valve and Vent Inflow Preventer Assemblies for Potable Water Distribution System and Storage Facilities are covered. Chapter topics include: locating air valves along a pipeline; design of valve orifice size; water hammer effects; and installation, operation, maintenance, and safety.

Описание: The presence of iron and manganese in drinking water are generally not hazardous to health. However, there are few things are more alarming to customers than seeing red water or black water come out of their faucets. This book offers an analysis of current and emerging methods for iron and manganese removal as well as guidance for handling residuals. Using firsthand field experience and detailed case studies, the authors explain the processes to follow.In this new edition, more detail is devoted to the selection and design of the treatment process and to minimizing the use of vendor-engineered packages that have become so common throughout the industry. Unit processes are described and calculations are provided so that the reader can understand the impacts of changes to the design components. This edition also attempts to address the question of why decisions are made and standards followed.John Civardi and Mark Tompeck have donated their royalties from the sale of this book to the Hatch Mott MacDonald Endowed Scholarship at the New Jersey Institute of Technology.
