Guidelines put onus on water agencies, building managers to combat pathogens like Legionella
The Centers for Disease Control and Prevention (CDC) released new guidelines in the fight to prevent Legionnaires' disease. The publication of the toolkit is a step forward in offering practical guidelines to help building owners control Legionella bacteria once it has entered their buildings from the public water supply.
The 304 SS three-stage wall-mounted system provides particulate reduction, microbial retention and high-dose 186 mJ/sq cm ultraviolet. Its RLC monitor provides fail-safe monitoring with alarms. It is suitable for point of use applications. The system has been performance tested, evaluated and verified by the U.S. Environmental Protection Agency with live Cryptosporidium oocysts, adenovirus and the MS2 bacteriophage.
LightWise technology, featured on Viqua PRO10, PRO20 and PRO30 UV water disinfection systems, allows the controller to reduce lamp power during periods of no water flow, leading to estimated energy savings of 30%. By adjusting the power of the UV lamp, water temperature is maintained below 104˚F and the rate of sleeve fouling is consequently reduced by as much as 60%, more than doubling the amount of time between sleeve cleaning cycles.
Ozone is increasing in popularity in U.S. residential water treatment as an alternative to chlorine and potassium permanganate disinfection. The Food and Drug Administration (FDA) approved ozone for bottled water production in the 1980s, and it is now approved for food processing. The time has come for ozone to become a standard in residential water treatment as well.
Tips on explaining the benefits of ozone generators to homeowners
SmartStream, a solution for ultraviolet water disinfection applications in residential and commercial applications, provides automatic lamp dimming, which promotes energy savings, and automatic lamp identification, which ensures proper lamp energy management to maximize lamp output. The system has a small footprint, which eases installation.
Brown Brothers Winery in Milawa, Victoria, Australia, has been crafting wines since 1889, with more than 60 wines available for tasting. The third and fourth generations of the family are keeping the tradition alive and have forged a company reputation, locally and abroad, as a wine specialist and winemaking innovator.
Innovation can be found in all facets of wine production at Brown Brothers, including its water treatment. In 2009, the company replaced its existing ultraviolet (UV) disinfection system after experiencing bacteria counts of up to 100 colony-forming units.

Each spring, the quality of the process water at a pulp mill in eastern Canada would suffer when snowmelt generated large volumes of runoff into a nearby lake and its tributaries, pushing additional debris, dirt and iron into the facility’s aging clarification system.

Watts SmartStream UV is a new solution for ultraviolet (UV) water disinfection in residential and commercial applications. UV disinfection is highly effective in inactivating cysts, bacteria, viruses and parasites. Those organisms, if ingested, could lead to serious illness and even death.
Driven by the accumulation of fouling at the sleeve-water interface, maintenance time and costs remain significant challenges in the application of ultraviolet (UV) disinfection. New lamp-dimming technology can extend the sleeve cleaning maintenance cycle and contribute to labor and power savings for water treatment operations.
