Ultraviolet (UV) and ozone are clearly established as viable secondary disinfection methods to chlorine for combating recreational waterborne illnesses (RWIs).
Combining UV & ozone for increased disinfection & oxidation efficacy
Overall utility savings and disinfection benefits of cold water ozone-laundered linens are the prime factors behind the installation of ozone systems at many hotel operations, including the Holiday Inn Express & Suites in Atascadero, Calif. General Manager Amar Sohi was quick to add another reason.

AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
The primary focus of water treatment, regardless of source, is to optimize treatment equipment options and methods to provide consistent, potable water quality to the end user. The main immediate concern is the elimination of dangerous biological contamination through disinfection. As the industry develops new methods and learns more about historic processes, there is a series of options to utilize with various advantages and disadvantages.
Ozone disinfection options for systems large and small
The Winona Family YMCA is located in southeast Minnesota, in a town that is home to approximately 27,000 residents. The 4,300-member athletic center is spread across 78,000 sq ft and hosts programs and classes in badminton, basketball, tennis, aquatics and more.
Built in 1951, the original indoor pool at the Winona YMCA measures 20 by 60 yd. When a new, larger pool was built, the smaller pool became the YMCA’s warm-water pool, used for toddler and senior citizen classes, as well as therapeutic activities.

Independent study shows positive effects of cold water ozone laundering on extending the life of linens
ClearWater Tech officials discussed the many benefits, supported by an independent study, of the positive effects cold water ozone laundering has on extending the life of linens, at the Clean Show in New Orleans at the Morial Convention Center June 20 to 22.
Chlorine is and has been the No. 1 disinfectant used by water treatment systems throughout the world for more than 100 years. Currently, a majority of municipal water systems use chlorine to disinfect their drinking water. Recently, though, concerns over chlorine’s limitations have emerged, and research into alternative disinfectants is ongoing.
New disinfection options may provide alternatives to traditional chlorine
