Microfiltration and ultrafiltration have gained rapid acceptance as processes that provide a reliable and very high level of particle, turbidity, and microorganism removal. This manual contains information on low-pressure membranes in widely diverse applications, operations and system designs. It will help water operators, engineers, and management ensure the success of an installation.
Chapters cover topics such as water quality, membrane science and theory, system concepts, MF and UF membrane manufacturers, applications, pilot testing, design concepts, operations, cost, residuals...

As more water systems turn to safer alternatives to chlorine gas, the generation of hypochlorite on site has become increasingly common. M65, On-Site Generation of Hypochlorite, presents the principles of on-site generation (OSG), the differences between low-strength and high-strength OSG systems, and the subsequent impact each of these systems has on design, construction, and maintenance for water and wastewater utilities. M65 provides operators and engineering staff with a basic understanding of how to design and install both low- and high-strength OSG systems, how they work, and how they...

Effectively managing valves as an asset can have a significant impact both for the water utility and the customer. This revised manual covers valve selection and installation as well as the importance of location, condition, and frequency of operation.
The updated figures show commonly used valves and their components, including: globe; butterfly; plug; ball; cone; and gate. Special-use valves are also discussed, but the intent here is only to introduce their availability and applications.
The authors incorporate the latest methodologies and technologies for...

This utility operations manual provides drawings and approved procedures for fire hydrant design, installation, and operation and maintenance practices. It traces the development of the different styles and contains detailed instructions for testing. Definitions, diagrams, and record-keeping tips are included as well as easy-to-follow flow-testing procedures to quickly obtain valuable distribution system information. The bulk of the material in this manual refers to dry-barrel and wet-barrel fire hydrants; however, information is also included on high-pressure and flush-type hydrants....
