Ultraviolet Disinfection Handbook is an ideal engineering and operations reference for UV light water treatment.
The handbook describes the powerful capabilities of ultraviolet light as a water disinfectant. It describes the process by which UV inactivates and makes harmless microbes by altering their DNA, and how UV is measured and dosed to inactivate any type of microbe in your source water, including Cryptosporidium.
You will understand how UV can fit into your specific treatment scheme, whether yours is a large, medium-size, or small system using filtered or unfiltered water, an uncovered reservoir, groundwater, or surface water.
The book describes the effects of turbidity, algae, and other water quality issues on UV performance, as well as pretreatment that may be needed prior to UV, such as filtration or chlorine reduction.
Ultraviolet Disinfection Handbook provides the information you need to plan, purchase, install, and operate a UV installation. The book explains UV systems and equipment, including major classes of UV water treatment systems, types of UV lamps, UV sensors, sleeves, power needs, and control equipment. For utility managers, the book provides a list of specific questions to ask an engineering consultant, should you choose that route rather than using in-house staff.
Additionally, chapters provide complete guidance and information on key design issues, including UV transmittance; equipment fouling and aging; equipment location, layout, and site constraints; flow and hydraulics; and electric power.
The book explains USEPA requirements for validation of UV reactor performance prior to startup, plus operational requirements. You also will find helpful information on UV cost estimating.
When your UV system is ready to go online, you will find guidance for facility startup, recommended operations and maintenance tasks, recommended monitoring schedule, reporting requirements, and even troubleshooting. Safety gets a chapter of its own, as UV systems have unique safety issues in which operators must be trained.
